Mute swans tower above recent floods

As flooding affects the nesting season on the Ouse washes at WWT Welney, one pair of swans are towering above the lapping water.

A determined pair of mute swans are refusing to lose their nest to the flood waters at Welney.  Gathering what vegetation they can find, they are trying to weather the rising waters to continue incubating their eggs and hopefully hatch the cygnets inside.

As a result of the flooding on the Ouse washes this spring the breeding season at Welney has come to a standstill.  But one of the many pairs of mute swans which breed on the reserve is not giving up without a battle.  Since the waters came on they have increased the height of their nest from its origins on the banks of the ditch next to the footpaths.

Mute swans are native to the UK and remain close to their breeding territories all year round.  Visitors can see the mute swans up close in the winter at the swan feeds, during which time the reserve is home to an additional 10,000 swans migrating from more northerly breeding grounds.  But during the summer the whooper swans from Iceland and the Bewick’s swans from Arctic Russia are absent leaving the whole wetland site for the mute swans to use to hatch and raise their cygnets.

‘The water levels have now started to drop, relieving the pressure on this particular pair of mute swans’ says Marketing and Events Officer, Emma Brand.  ‘We hope the levels will continue to drop over the next week or two so that we are ready for the June half term activities, which include pond-dipping, moths on display and biodiversity blitz sessions’.

The water levels are now decreasing with hopes that the reserve will start to open up again to visitors and provide feeding areas for the birds once more.  Updated information on the access on the reserve and what activities are available can be found at www.wwt.org.uk/Welney .

Yet more sticks and more mating

Over the weekend we have seen both ospreys bringing in more sticks to the nest. AW as ever is a bit optimistic in thinking he can find the final resting place for his sticks on the nest. His mate rearranges his endeavours as sooon as he leaves. There have also been more mating attempts on the nest so things are looking good for an egg sometime soon, hopefully before the end of the week. Our pair are always a bit later than others, some of whom are already on clutches of 3. AW’s mother at Wigtown Bay laid her first egg of the season on the 15th and the second should be very soon. We have also seen good views of AW’s tail feathers over the weekend as he perches on the branch holding the CCTV camera at the nest. Thankfully the black plastic does seem to have blown away and no more has been seen. Just after midday today I could see an osprey perched on driftwood just off Saltcot merse and it looked to be eating a fish. It was too far away and too hazy to see if it was a ringed bird.

Expecting eggs

We are all eagerly expecting eggs to be laid by our osprey pair in the next few days. There has certainly been plenty of matings and lots of nest additions and ‘cup scraping’ which are all good signs of the birds being well bonded to the nest site and being ready to lay. Luckily it looks like the black plastic which was adorning the nest has gone as it could pose a real risk to chicks, by entangling or smothering them which has happened elsewhere.

Visitors have been asking how we will know which of the two male birds may be the father of the eggs and whether there is any risk of the male AW destroying them if the are his rivals’ (as happened at Loch Garten a few years ago). The answer is all in the timing- ospreys generally lay eggs 7-10 days after mating so if any had appeared last week we’d have know they were fathered by the first male. Since the 7th of April only AW has been mating with our female ,so if the eggs are laid from now on, they will be his. Let’s hope thats the end of any domestic dramas for the year!

Osprey eggs have now been laid at several UK sites this season, such Wigtown Bay, Glaslyn, Tweed Valley , Loch of the Lowes, and Loch Garten, so hopefully our birds will join the list very soon.
