Still two eggs

The ospreys are still basking in sunshine and we still have a clutch of 2 eggs. It has been quite difficult to see what is actually going on in the nest cup due to the mounds of grass and sticks that the female has heaped up at the edge of the nest. Today AW took his turn on the nest for almost 2 hours over lunchtime before his mate took over again, when he stood up we could clearly see at least 2 eggs, the very dark almost brown first egg and the more speckled second egg.

With the increased daylight and sunlight hours we now have enough solar power to beam live CCTV images to the visitor centre from 10am till we close at 5pm.

Still no third egg

At the end of the CCTV recording yesterday I could still see only two eggs on the nest. This morning the female has been sitting tight on the nest most of the morning and has built up the grass and twigs at the front of the nest so that it is difficult to see the eggs when she stands up to turn them. Hopefully I will get a chance to see what is going on later on and update today or tomorrow morning. Still basking in spring sunshine which is always a good thing for the birds.

Can’t see the third egg yet

Like yesterday AW has been doing a lot of nest duty today sitting on the eggs. He spent nearly 2 hours this morning before his mate came in and took over. Due to the build up of nest material on the edge of the nest it is very difficult to see if a 3rd egg has been laid this morning. Hopefully I will be able to see what is going on this afternoon on the live feed, if not I will have to go through the DVD later to se if I can get a glimpse of the eggs when they stand up and turn them or change over. At 1.10pm AW arived back on the nest empty handed and stood on the edge of the nest for 10 minutes before flying off again. Maybe she is in need of a fish, she was calling to him when he left. I hope to post another update later this afternoon with an egg update.

No sign of egg number two yet

It looks hot on the osprey nest today as the birds bask in the spring sunshine. AW has flown in to take his turn on the nest 3 times today, once with a fish for his mate. We have also seen a mating attempt on the nest this morning, a precarious operation as the female sits on the egg! By 4pm this afternoon there was still no sign of a second egg, hopefully later this evening or tomorrow morning.

Good news from AWs home at Wigtown Bay, HD & EP have a clutch of 3 eggs.

More good news from NTS Threave, 5 ospreys were seen at the nest site yesterday and the regular pair sat tight on the nest till the 3 interlopers flew off.

Dumfries & Galloway is fast becoming a great place to watch opsreys with three very different viewing sites. here at Caerlaverock we have live CCTV from the nest and a chance to see the birds fishing in the Solway. At NTS Threave near castle Douglas you can actually see the nest from a special viewing platform near the castle and at Wigtown bay there is one of the best CCTV systems beaming live images to the Town Hall viewing room. There are also other birds about so you never quite know when you may see one of these spectacular birds in this area.

First egg laid this morning

As the CCTV system came on at the centre this morning the female was sitting tight on the nest. Was she on the first egg? Emma watched patiently and at 10.20am she saw the female stand up and sure enough there was the first egg of the season in the cup of the nest. AW came in with a fish for his mate just after 12 noon and she flew off to eat it and he took over the incubation duties. She cam back half an hour later and gave him back the half eaten fish and took her place on the nest as he flew off to finish it.

Emma had calculated that today would be the day as it is exactly 9 days since the first successful mating attempts were seen on the nest. It is great to have such an osprey expert on the staff here at Caerlaverock.

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.
