For anyone with any concerns about Telyn's ability to look after herself, she's just fine. Here she is with a whopping mullet just before 5pm. That should keep her going for now.

...Idris struggled with his slippery fish on perch bar for a while, didn't got enough grip to decapitate the fish further and took off into the marsh.

Do you ever feel ‘half asleep’?
Birds do - literally.
They can’t afford to shut down the whole brain to sleep due to predation pressures, so they shut one side of the brain down at a time. The eye connected to the sleeping half of the brain closes; the eye of the wakeful hemisphere remains open and vigilant.
This is called Unihemispheric slow-wave sleep (USWS).
Here’s Telyn last night just before being ‘half asleep’.

Great news: Merin is back at his Cumbria nest site for his second year of breeding there.
You may remember he raised two chicks (pictured) at this nest last year.
Merin initially had a breeding attempt in Denmark, but was unsuccessful; he is Monty and Glesni's son from 2015.

Hello from France and precisely from Orléans next to Sylva and Reda's nest. This pair has returned and already has two eggs.
So much for the presentation.
I come back to you concerning the osprey named Merin. If I understood correctly he was in Denmark for the first time and then he came back to England.
Thank you for all your information which I try to follow regularly. Indeed I work and it is not easy to regularly follow my favorite nests all over the world.
As I don't know if you use the translator (which I do) I am writing to you in English.

Claire, welcome to the forum
All the best for Sylva and Reda for this season, may they rise strong and healthy chicks also this year
About Merin - I read it as you do, he was in Denmark for a very first breeding attempt (which failed), came back to England and bred there successfully already once and is now up to a second breeding attempt in England.
English is our forum language, so well done in your first post

Wild animals can't afford to be wasteful; do ospreys eat all of their prey?

Do ospreys retrieve dropped fish?
Millions of years' worth of evolutionary adaptions have afforded ospreys several advantages over other raptors when it comes to holding their prey.
Small spiky skin pads called '𝙨𝙥𝙞𝙘𝙪𝙡𝙚𝙨' on the underside of the toes help to grab fish, as do backwards-facing scales on the talons which act as fish-grabbing barbs.
Ospreys can even reverse their outer toe (𝙯𝙮𝙜𝙤𝙙𝙖𝙘𝙩𝙮𝙡 𝙩𝙤𝙚 𝙖𝙧𝙧𝙖𝙣𝙜𝙚𝙢𝙚𝙣𝙩), enabling them to have two toes each side of the fish like a biological fairground grab-claw.
Despite these adaptions, the odd fish does go overboard now and again - as did this mullet caught by Idris yesterday. No sooner had he passed it over to Telyn, she dropped it.
Sometimes ospreys will retrieve their dinner, sometimes not. Neither Telyn nor Idris decided to pick up this mullet yesterday.
In the first comment under this post, see a video of Monty dropping his fish - and then retrieving it!

A brace for Telyn and Idris!!
A little later in the day than expected, egg number two has arrived at 18.01, fresh out of the paint shop. Look out for the hat-trick on Friday.

Egg No 2 (left) has much more 'maculation' than the first egg as you can see in this photo.
Each egg is different and we try and use these differences to identify which egg is which in a clutch. It matters not to the ospreys, of course, but for biological recording and analysis we have always been able to identify what order an egg/chick was laid.
Thing is - and this is a proper question - there is so much pigment (protoporphyrin) in the second egg, will Telyn be able to make enough for a third?
We've seen plenty of eggsamples in the past of almost pure white eggs - Gwynant (2014) being the obvious one.
Has the ink-well run dry? We'll know on Friday afternoon.

Telyn completes the Hat-trick!
3rd egg arrived at 17.07. Will this be the full clutch? We'll have to wait and see.

Telyn incubated her three eggs all night except for a quick toilet break just before 5am.
Osprey chicks take between five and six weeks to hatch, so eggspect the first sign of life from around 23rd May onwards.
We can see the ospreys at night thanks to an infrared lamp on the camera pole. This is light at the long end of the spectrum that is not visible by humans nor any other mammal. Birds can't 'see' infrared light either; no warm-blooded animal can.
Fear not, we don't have a nocturnal ink thief - those three eggs in the nest have pigmentation on them, it's just that the IR light can't see it

We have some very sad news to tell you.
Our beloved Posh Pete (Peter Murdoch) passed away last night.
Pete has been a familiar face to thousands of visitors since he started volunteering at DOP in 2010, it's come as a great shock.
Many of you will have met Pete if you've visited DOP, most of you will know him from the annual Posh Pete Test videos when naming our chicks each year.
This evening DOP is a little poorer, a part of it missing.
