New kid on the block

We thought that the nest with 21 eggs would be abandoned as happened last year when two tufted ducks kept laying eggs on top of each others' and none of them hatched. To our amazement I spotted some ducklings inside the nest box 10 days ago and later in the day their mum persuaded them to take to the water.  Only five ducklings hatched and one dived the moment it 'hit' the river.  We think one may have been injured as it didn't join the other four with their mum so, with a little help from a neighbour, we reunited them all within five minutes but the mum rejected the rescued duckling. Shortly afterwards she and four ducklings returned and we never saw the fifth one again.

Five 'tuftie' ducklings shortly after hatching

The mother soon brought her four ducklings back to the nest box for a rest and for several days they used the old nest, still with 16 unhatched eggs, for resting and sleeping.  

 The four stayed close to their mum at first

Mum, with some of her brood, stretches her wing 

After several days the ducklings became more independent and headed off in all directions, with a tendency to follow any duck or goose that swam by!  It therefore didn't come as a surprise when first one, then a second baby disappeared.

By day five only one baby remained and it raced after any passing waterfowl regardless of size or breed.  Sometimes its mum would be with it for a while and then she'd fly off a short distance and the little one would do its best to 'scoot' across the water to keep up with her. It appeared to get quite distressed and would call pathetically for its mum but she would abandon it for long periods and suddenly turn up again and stay with it for a little while. The pair would sometimes attempt to go into the neighbouring nest box, which was occupied, but ignored their old nest even though it was now clean and with fresh straw.  Scooter, the nickname soon given to the little tuftie, is still with us and adapting well to life with and without his mum.  They are together on a regular basis so Scooter hasn't been completely abandoned.

A sickly looking baby coot 

We don't know what the coots have been up to this year but assume that their first batch of eggs was either sterile or stolen by the magpies and crows.  The coots occupied their nest box for several months and I'd given up on them ever hatching any young. The surprise of hearing the winging tones of a young coot alerted me to a new arrival but it really didn't look healthy. One of the parents tried its best to encourage it back towards its nest but it drifted downstream and really struggled to swim back. As I was watching my concern turned to alarm when a herring gull suddenly spotted an easy meal and began to circle and swoop on the defenceless baby coot.  The adult did its best to defend the youngster and I tried to frighten the gull but it was determined to dine on a baby coot and, with a final swoop, plucked the baby from the water and flew off with it.  I felt really sad for both parents but the next day another sickly youngster appeared then was gone within five minutes.  I didn't see what happened to it.

The determined adult coots started laying yet more eggs and I spotted two before a magpie also noticed the eggs and began stealing them.  Finally, with no eggs to show for their efforts the coots gave up and abandoned the nest.  

 Eight days later . . . 

For several days I checked just in case the coots had come back but there was no sign of them. I gave it a few more days and then removed the lid of the nest box to clean it out only to discover a neatly formed nest with six eggs!  I kept an eye on the ramp up to the nest box and spotted a female tufted duck entering and leaving the box.  It hadn't taken her long to avail herself of the unoccupied nest. We think she may be sitting full time now because Scooter and mum aren't able to go inside the box. We don't want to spook the duck so we shall just have to be patient and see what happens.  

Cheeky teenage mandarin ducks

I was sitting at my computer the other day with the patio doors wide open as it was warm and sunny. I became aware, in the background, of the sound of mandarin ducks, but was concentrating and paid no attention.  A little later I got up to answer the phone and found the three young mandarin ducks wandering around the living room!

The guilty trio swim away with their mum

Fortunately they hadn't left any calling cards so I very carefully headed them in the direction of the patio door.  I didn't want them to panic as they would be more likely to make a mess on the carpet if they felt trapped.  Once outside, they remained on the deck and waited for me to put some wheat down for them.  Meanwhile mum was keeping a beady eye on them while feeding from the container on the deck table.

The female mandarin duck that had four a while back now only has one but it is surviving well and is even tamer than the three above. It taps on the glass doors if it can see me and there's no food on the deck!

Many of the ducks are beginning to moult now and the red crested pochard is no exception. However, he doesn't look nearly as pathetic in moult as do the male mandarin ducks.  They look dreadful when they loose most of their striking plumage.

I haven't been checking the upstairs nest box for a while but thought to do so yesterday only to discover that Flare Tail has laid three eggs and is keeping them well hidden.  I'm doing my best to protect the nest from marauding magpies and the crow as it would be really sad to see the eggs stolen. Once a predator has found eggs in a nest it comes back for them all and we have a large family of young magpies whose parents are doing their best to keep them fed.

Cygnet watches mum preen

The cygnet is growing up but still has its lovely 'baby' feathers.  It copies its parents when they stop to preen which is lovely to see. There's something therapeutic about watching swans and ducks preen.

More ducklings

Lonely, the black hybrid female duck, hatched 10 ducklings two days ago but was soon down to seven.  She's doing quite well, under the circumstances, as she is frequently attacked by drakes and driven away from her youngsters.  The herring gull has also been patrolling the river at low level to snack on any duckling foolish enough not to stick close to its mum. Pike are also taking their share of young waterfowl including ducklings, moorhens, coots and very young cygnets.

Lonely and some of her brood hurrying away from an aggressive drake

I was surprised to see Lonely feeding from the table where the mandarin ducks like to be fed.  Over the years only three mallards have attempted to feed from there and she's a match for the mandarin ducks, seeing them all off.  I'm delighted to say that even the aggressive pigeon awaits his turn when she's around.

 Our cygnet seems to think it's a contortionist

Proud parents admiring their offspring

Following a discreet romantic interlude the swans face their youngster who appears to be singularly unimpressed.  The family calls round at least six times a day at the moment, mostly so that the cygnet can tuck into some wheat.

Flare Tail has been looking for a new nest over the last few days and this morning was checking out her old nest box and then the one on the other side of the garden deck.  I need to put more straw in that one if she's going to start laying more eggs.  

Ugly duckling indeed!

Cygnets are so endearing and 'our' cygnet grows more lovely every day.  The pen brings it round five or six times daily and I always take the time to stop what I'm doing and admire it. The cob is sometimes with them and there's trouble if another swan happens to be in the vicinity.  Both parents race after any rival and the cygnet is left to paddle after them as fast as it can, calling out in distress at being left behind.  Fortunately, once intruders have been driven off, the pen returns to allow its exhausted cygnet to climb back under her wings.

 Mum takes the strain

The swans nearly always approach us from downstream so I have plenty of time to get out their favourite food for them.  Sometimes the cygnet gets so excited at the thought of a 'wheat treat' that it slides off mum's back before reaching the feeding station - but not always!

 Time to slide off mum's back for some wheat

Usually it stays on board till the last minute and then wriggles from under its mum's wings before sliding into the water.

Getting back on takes a little more effort

After a substantial snack it's so nice to clamber back under mum's wings but it's never that easy, especially when mum is seeing off a rival swan. Then the cygnet has to paddle hard to keep up with her.

Preening is essential 

After a good meal it's important to preen before settling down for a snooze under mum's protective wings.

Mandarin duck brings her babies

One of the mandarin ducks brought her ducklings to see us on Wednesday.  There were nine of them to start with but she was down to seven yesterday evening.  She has decided to use the empty nest box on the river for the night and once she has ushered them into the box and followed them in, her mate stands guard for a while at the entrance to the box. She has done this for the last two nights, which is great, but there is now a complication.  I discovered yesterday that a duck has laid two eggs in the nest!  A pair of tufted ducks has been hanging around so I think the egg is probably theirs.

Mandarin duck with her newly hatched ducklings

Unfortunately one egg was broken when I checked the box yesterday afternoon.  I'm not sure whether it was broken accidentally by the mandarin ducklings and their mum or whether a magpie or crow has discovered the eggs.  There is also a third possibility in that the coots are fiercely protective of their own nest close by and have been 'inspecting' the box rather aggressively.  I decided to remove the broken egg as it would have made the box smell terrible after a couple of days. I also added more straw to hide the remaining egg.  When I peeped inside the box late this morning I was pleased to see that there are now two unbroken eggs and the additional straw has provided good cover and also an extra layer of protection.

One of the seventeen male mandarin ducks that visit daily

I should imagine it won't be long before another family of ducklings arrives on the scene but we shall have run out of accommodation if the coot doesn't hurry up and hatch its brood.

I haven't seen Flare Tail's ducklings for some days but she may still have at least one as she is in the habit of flying in twice a day to wolf down some wheat before flying off again.  I think that if she had lost all her ducklings she would remain in the area for much longer.  I do hope I'm right and not being unduly optimistic. 

Cygnet and goslings

I think that Flare Tail may have lost her ducklings.  They appeared on their own a couple of days ago and I thought they might be safe as they seemed to be quite happy to lurk in the shallows between our boat and that of our neighbour's.  Flare Tail and her partner, however, spent quite a long time resting in the sunshine on my therapy room's roof the other morning so I'm wondering whether she has either abandoned them or has taken them somewhere safer and heads back to see them after taking a break.

We used to have a mallard duck we called Goldeneye, also with a brown hybrid partner.  She was a disastrous mother, abandoning her ducklings within a day and a half or hatching them as if she got bored and couldn't be bothered with them.  I do have just a smidgeon of hope that Flare Tail has her ducklings safely stowed upstream as she flies in to feed and then heads off again in a hurry. I'm keeping my fingers crossed and hoping that she's been clever and taken them somewhere safer than our location.

 Canada geese with goslings

The Canada geese are excellent parents and are fiercely protective of their young.  Even so, this pair now only has two goslings - I'm not sure what happened to the third one.  Of an evening they bring them to our floating platform for the night and I haven't the heart to turn them away though they are not my wildfowl of choice as I've seen them attack ducklings. 

Resident swan with cygnet

Our resident swans were unlucky this year and their nest was regularly raided by magpies and possibly a crow or heron. Hence only one cygnet but they are taking great care of it and it's a joy to watch it sitting proud on mum's back.  They visit the feeding platform three or four times a day and the cygnet seems to enjoy small amounts of wheat as a supplement to its diet  This morning I laughed out loud as the female swan stretched her neck down to retrieve some wheat that had sunk into the riverbed, tipping the cygnet unceremoniously into the water.

Another surprise awaited me this morning. One of the mandarin ducks appeared with 9 or 10 ducklings.  She's very nervous and protective of her newly hatched youngsters but I'm hoping she'll use the spare duck nesting box as a creche for them tonight.  She visited the feeding station several times today with her ducklings but is very wary of humans.

Flare Tail surprises me with three ducklings

Flare Tail surprised me by appearing with three ducklings yesterday.  I wasn't sure when she'd started sitting full time so I couldn't predict the exact day when the 'chicks' would arrive.  I probably should have guessed that ducklings were due any moment because she didn't come to be fed at all on Tuesday.  The first I knew of it was when she and her mate swam past with three ducklings in tow yesterday afternoon.

She's obviously attractive to other drakes because she has been chased on a regular basis and you can see by the scar on her head that she's received some pretty rough treatment.  Last night she was trying to lead her three babies into the empty riverside nest box for the night but was attacked and was forced to leave the ducklings to fend for themselves.  I didn't hold out much hope that they'd survive as they tend to swim off downstream when abandoned and I saw no sign of Flare Tail for the rest of the evening so I was delighted to hear three ducklings calling for their mum this morning. They seemed quite happy to feed on their own while they waited for mum to return and at least they weren't chased or pestered by other ducks.

Flare Tail's kids - two real mallards and a hybrid

She tried a number of times to be with her ducklings but was chased by rogue drakes until they got bored or she managed to elude them.  Finally she reappeared and was left in peace to join the youngsters. Later this morning she and her mate came to feed with the ducklings in tow but I've seen and heard nothing more of any of them today so I hope they're okay, especially as I've just noticed a herring gull on the hunt for a tasty morsel.  Fortunately it was driven off by a crow but then crows are almost as lethal.  I've seen a fair few ducklings plucked from the water by our resident crows.

Flare Tail, looking the worse for wear, with her mate

We are sometimes joined by a pair of red-crested male pochards and occasionally a female joins them but I think she must be on a nest as I haven't seen her for at least a week.

Male red crested pochard in bright sunshine

I don't remember whether I mentioned the fact that 'Squeaks' the lovely old Aylesbury duck must have died.  She had been visiting less frequently and her feathers were looking very bedraggled plus she seemed to have damaged her leg so I guessed that she was nearing the end. When she appeared a couple of weeks ago looking worse than ever she seemed desperate and confused and I wondered whether to call Swan Rescue but decided that it would be too traumatic for her to be grabbed and removed from the river as she was a very old duck.  She would also have missed her male entourage of three suitors.  I was really upset to see her like that but I've learned that it's sometimes wiser to let Nature take its course.  I never saw her again and hope she didn't suffer.  At least she was with her mates and one in particular, a 'stretch-limo' of a hybrid duck, really seemed to look after her and stay by her side.  I do miss her and the excitement she always expressed when she came for her wheat treats.

First ducklings

Yesterday evening Lonely appeared with 10 ducklings.  They are the first I have seen this year so it was exciting and I'm looking forward to when Flare Tail's ducklings hatch which should be in a few days.

Lonely's clutch of ten

Lonely appeared when the light was low so it was impossible to get a better image of her newly hatched brood.  She is a nervous duck too, especially with her 'babies' in tow, so she turned tail as soon as I went out with the camera to grab a photo.

This morning she arrived with only eight ducklings and by 10.00am she was down to seven. I wonder how many she'll have by this evening!

The attrition rate is always high at this time of year but although I know this I am always sad at at the loss of so many new lives.  The reality is, of course, that there would be far too many ducks on the river if most of the ducklings survived.

The mandarin ducks are multiplying!

There seem to be more and more mandarin ducks on this stretch of water.  Over the winter months they put on quite a cabaret for us at feeding time.  We had as many as 17 pairs and a spare come to visit us every day and it was fascinating to observe the 'pecking order' when it came to which ones were the dominant ducks.  Most of them like to feed from a small bowl on the table on the deck but in theory there is only room for three or four at the most.  However, at times 7 or 8 would pile on top of each other, literally standing on each others' backs to get at the wheat. The ducks lower down in the 'pecking order' couldn't even get near the bowl and had to make do with feeding from the deck and even among those ones some were more subservient than others.  

They don't get things all their own way, however, as two determined pigeons do their best to get to the wheat first.  One of them swoops in and karate kicks the ducks and then bashes them with its wings! It has a powerful beak and generally succeeds in scaring the ducks although there are three or four mandarins that attack back and successfully defend their corner.

Now, during nesting season, the mandarins arrive in the morning at various times, feed and fly back to the nests but in the evening they still turn up 'en masse' and are much more fun to watch than the evening news!

The grebe I saw with two youngsters was around yesterday but only had one with it.  It is possible that the second baby grebe was with the other parent but there is a high attrition rate among grebes at this time of year.

The tufted ducks still hang around but none has shown signs of nesting as yet.  I'm sure it won't be long before a pair tries out the spare nest box on the water.

A female tufted duck 

This particular 'tuftie' has quite a large area of white just above its beak but most of them don't.  She's been around for several years now so I recognise her as she has become used to used to us feeding her.

Flare Tail is still sitting on the nest, though she was driven off it the other day, probably by a rogue drake.  The coots are also incubating their eggs still but I think there will be baby coots quite soon now.

Spring 2015 - early arrivals

It has been a beautiful warm and sunny April and both the garden birds and the waterfowl have been busy building nests and laying eggs.  Two of the duck nesting boxes are occupied, one by Flare Tail and the other by coots, the same pair that adapted to nesting inside a duck box last year. Meanwhile the blackbirds have been raiding our bog garden for suitable material with which to line their nests.

I'm not expecting Flare Tail's ducklings to hatch until about 10th May but we may have baby coots a little sooner.

We were rather surprised to see that a pair of great crested grebes had two youngsters.  Late last week I noticed them tucked away under the wings on mum's back while the male did its best to feed them. He finally managed to present a fish to the family but it looked rather large for one of the babies.   After at least half a dozen attempts to swallow the fish one of the youngsters finally succeeded although it took some effort!

The parents present a fish to one of the babies

It was quite extraordinary to see just how patient and caring both parents were.  Shortly afterwards the male dived again for more food and suddenly a rival grebe appeared from nowhere and attacked the mother and babies.  She dived to escape, causing both youngsters to fall off her back. They surfaced close by while she led the attacker away from them.  Fortunately she escaped and swam back to them calling franticly to her partner who soon drove off the rival.

Ducklings and baby tufted ducks

Two tufted ducks fight over incubation rights

Just before we went on holiday we were able to capture this dispute between two female tufted ducks inside the nest box.  Both had laid eggs in the box and both wanted to incubate the eggs but the dominant female drove off her rival.

Rival 'tuftie' waits patiently at the nest entrance

After sitting at the nest box entrance for a while she finally gave up and left the eggs to the occupant!

Finally she is seen off

While we were on holiday we thought that we would miss hatching day but the female tufted duck was still sitting on some eggs when we got back.  Some of the ducklings had already hatched on the Saturday evening and she introduced them to the river the next day with a little help from us as some were reluctant to leave the nest. She swam off with seven youngsters and we didn't see her or the babies for several weeks.

Mother 'tuftie' trying to keep up with her ducklings

When the ducklings took to the water a second female 'tuftie' was hanging around by the nest box and we guessed that she must have been the unlucky one.

Mum turns up with two remaining ducklings

After about 10 days we were delighted to see a female tufted duck with two youngsters.  We think it was our girl because she spent time near the old nest box and wasn't phased by our presence.

Baby dives for food

Mother and babies stayed with us for about an hour and we watched with delight as the babies dived for food and swam around close to their mum.  Sadly we haven't seen her since and as the ducklings were so young it's possible that they didn't survive. 

Mallard duckling

In spite of the fact that three mallards and a tufted duck all hatched ducklings using our nest boxes we saw no sign of any ducklings for weeks and had assumed that none had survived.  To our surprise, last week, on the same day as the tufted duck brought her two babies back to visit us, another tufted duck arrived with four medium sized ducklings, a mallard turned up with two baby ducklings, another mallard arrived with eight (we think it's Flare Tail who hatched twelve ducklings in a nest box on our garden deck) and Lonely turned up with two youngsters.

More comings and goings in the duck world

Last weekend we helped the mallard in nest box 1 launch her ducklings.  She led them upstream and that's the last we saw of them.  Once I'd cleaned out her box and placed fresh straw inside, a tufted duck, probably the one that has already laid some eggs in box 2, showed signs of interest in the box. We've seen her enter the box a few times now and on Friday an obvious nest scrape appeared. By Saturday, however, it had been flattened out and yesterday we were amazed to see Lonely, the black hybrid duck, lead 7 ducklings out of the box!  She's been using it as a creche for her babies.

 Four of Lonely's seven ducklings

We don't know where Lonely nested but she has been hanging around all day with her newly hatched ducklings.  Originally she had been looking at one of our top deck boxes but obviously found somewhere that suited her secretive ways better.

It was amusing to watch her various attempts to lead her ducklings up box 1's plank during the day yesterday.  She'd succeed in leading three into the box and the others would swim under the box and call out to her.  Sometimes she even managed to persuade all seven up the plank but some would fall off and she'd have to come out of the nest box to encourage them to join her.  As soon as she left the box to collect the recalcitrant ducklings those in the box would follow her out and the whole farce would start again.  Eventually persistence paid off and all seven followed her into the box.

Lonely with her seven

She spent much of yesterday travelling up and down our stretch of the river and giving the ducklings regular rest breaks on either our large plank or inside the nest box.  I hoped that she would use the box as a creche last night and we were delighted to see her lead all seven ducklings out of box 1 this morning.

A couple of minutes ago Dave heard a lot of splashing and quacking outside box 1 and saw Lonely attacking a female tufted duck.  It would seem that Lonely and her ducklings were resting in the nest box and a female tufted duck tried to enter.  She was soon seen off but is now hanging around again after Lonely decided to take her ducklings upstream.  In fact, Dave's just told me that the tufty has just gone into box 1.  We think she must be the tufted duck that has spent over an hour this morning sitting outside the entrance to box 2 staring at the occupant tufted duck.  We're pretty sure that both tufted ducks have laid eggs in the same box, hence the appearance of two ducks in the same box on occasions.

Meanwhile, Flaretail surprised us by appearing with several ducklings out of the top deck nest box. When she felt it was time to launch the ducklings some of them refused to leave and she became very distressed.  Eventually we placed the reluctant ducklings in a net and carried them down from upstairs to place them in the river.  Flaretail headed off with all twelve ducklings and that's the last we saw of them, too!  Only Lonely seems to have kept her ducklings in the area and, so far, kept all seven of them safe from predators.

 Cute coots!

The two young coots are growing apace and spend most of their time with us.  I couldn't resist this image of one of the youngsters tucked into the empty feed box.

Ducklings at last

We've been monitoring nest box 1 using an internal camera and were delighted, at the weekend, to see signs of the ducklings starting to hatch. It usually takes about 24 hours before all the ducklings have hatched and are ready to be led to the water by the female mallard. Not all the ducklings are keen to take their first swim and it sometimes takes a fair amount of coaxing by 'mum' to get them to join her.

First one out

When the mother thinks it's time to 'launch' her brood she leaves the nest and quacks loudly at the ducklings in an effort to get them to follow her. Some are keen but others have to be persuaded and the longer the process takes the more fraught the mother duck becomes. With only one duckling prepared to join her our mum headed back to the nest box to persuade the rest of her brood. 

Mother duck tries to persuade her other ducklings to join her

When only some of the ducklings are in the river the mother faces a dilemma.  If she leaves those in the river and returns to the box the ducklings in the river may disperse and be lost.   Meanwhile, because she can hear the babies inside the box emitting their high pitched calls to her, she won't abandon the remaining babies.  While our mallard was still in the river with a single duckling, a tufted duck nesting in box 2, came out to see what all the fuss was about and attacked the duck and her duckling.  The duckling dived and disappeared and the mother got even more distraught so we decided to lend a helping hand and lift the remaining ducklings out of their nest and place them in the river with their mum. 

A reluctant duckling

One of the ducklings was still reluctant to leave its nest and tried to get back inside! We had to turn it around and persuade it to join its mum.

 It's safer on mum's back

We were worried about the duckling that had been attacked but it soon rejoined its mother and decided to jump on her back for safety. I've never seen a duckling on its mother's back before although swans and grebes carry their young on their backs.

 This is fun

The duckling seemed to enjoy the experience of a free ride on mum's back but was soon shrugged off.

The female tufted duck from box 2, the one that attacked the mallard and her duckling, has been having problems of her own. While we've been monitoring her box we were amazed to see another female tufty sneak in while she was away from the nest. When she returned she did her best to force the intruder from the box being careful not to damage the eggs. This has happened several times since then and we're a little confused as to which tufted duck is the original 'tenant'. We have a suspicion that another female has also being laying eggs in the same box, hence the attempt at a 'take over'.

This tufted duck has attitude

We think this must be our nesting tufted duck, the one that attacked the mallard. She is determined to defend her nest box and is aggressive towards any other duck in the vicinity of her home! She had a real go at the mandarin duck (above) when it tried to join her on the plank. They got into a furious fight and eventually the tufted duck drove off the mandarin duck. Usually mandarin ducks are the most aggressive but our tufty is definitely feisty.

Our tufty sees off the mandarin duck

Once the mallard in box 1 hatched her ducklings and led them off upstream I cleared out the nest debris and poured boiling water into the box to kill any mites. When the box had dried out I put fresh straw inside in the hope that our mallard would bring her young ducklings back to the box to use as a night time roosting place. We haven't seen her with any ducklings but this morning another female tufted duck was checking out box 1 and it's possible that we'll have another duck taking advantage of the box 1.  

Musical nest boxes

After the mallards had abandoned their nest, having had all the eggs predated, I tidied up the box and forgot about it for a few days. When I went to check it and add some more straw, in case the mallards decided to start nesting again, a tufted duck shot out of it as I lifted the lid.  I'm not sure which of us was more taken aback!  Inside were three eggs so the female tufty must have occupied the box the moment it was abandoned by the mallards.  She had been hanging around both nest boxes for a long time and had already laid three eggs in this box several weeks before but had been 'kicked out' by the mallard.

Three 'tufty' eggs

The tufted duck has really had to defend her nest, however.  Every day the mallard pair attempt to re-occupy the box and the tufted duck has to fight her corner.  She hardly ever leaves the nest which means that the mallards aren't able to sneak back in during her absence. The image below shows the female mallard attempting to take back her old nest.

 The mallard refuses to give up her nest box

 Female tufted duck finds her nest occupied

On one occasion, during a brief absence from the nest, the tufted duck was unable to re-enter her nest box  because the mallard had reclaimed it.  The tufty squatted outside the entrance to the box looking miserable for a while and then swam off and 'sulked' with her partner on our 'chill out' plank.

The 'tufty' pair retire to the plank

Drake is driven from nest box by female 'tufty'

I don't think the mallards are really ready to start nesting again. Although they regularly try to reclaim their old nest they don't hang around for long.  The female tufted duck was able to return to her nest after a while and, later in the day, drove away the mallard drake when he was unwise enough to put his head inside the nest box!

 Female mallard refuses to abandon 'her' nest

Every day the mallards persist in checking out their old nest. They hang around for a while but are gradually getting used to the idea that the female tufted duck has no intention of relinquishing her new home.  She is extremely feisty in the defence of her eggs!

 Female 'tufty' takes a break for a snack

Male 'tufty' preparing to dive for wheat

Yesterday I saw the tufted duck behaving in a distressed manner and noticed that she had an egg in her beak and was carrying it away from the nest box.  She appeared to be eating the contents of the egg. While she was off her nest I checked inside and saw yolk covering the bottom of the box. 

When the tufted duck returned to her nest she spent over an hour clearing up the mess, moving straw around, carrying soggy straw away from the box and eating as much of the spilled yolk as possible. I had added some fresh straw while she was absent and she gradually used this to replace the mucky straw that she had thrown out.

Later that day I saw a crow about to raid the box so I guess that the crow must have broken one of the eggs as it tried to steal it.
