Double intruder problems! Or treble!

For the first couple of hours of camera streaming on Friday nothing much happened. An osprey was on the camera pole at Nest 1, a bit later both YA and Mrs YA were on the nest and Mrs YA moved a stick about. On Nest 2, White EB is still around, making a brief appearance on the nest before 11.00. But the calm didn’t last until noon.

After a mating attempt by 37 which White EB was marginally more receptive to, he mantled almost straight after. Just showing submission perhaps? But no, both ospreys started shouting and mantling, then who flew off to send an intruder packing? White EB! She returned, Yallow 37 flew off. There was anxiety on the nest for about 20 minutes and at one point a brief glimpse of an osprey confirmed the problem was on of their own species. Gradually peace was restored and 37 celebrated by landing on White EBs back. One possible ‘intruder’ could be Mrs 37. Which would be very sad. We’ll never know, although maybe there is a clue that it wasn’t her.

Because on Nest 1 about half an hour later Mrs YA Edit: not the 2013 mate of YA, but the female from 26/3 started mantling furiously and down came another osprey onto the nest! It walked around, ending up in the corner out of sight of the nestcam. Enough was seen to be 95% certain it wasn’t the Nest 2 unringed female. It could possibly be the intruder who flashed across the nest on Wednesday just after YA returned.  A bold bird, it sat firm until Mrs YA eventually puffed herself up and made a run at it! The intruder flew away but only to a nearby tree and made a couple more landings in the next couple of hours. Where was YA?

We hadn’t seen any fish deliveries all day and the ospreys’ crops looked fairly empty. At 15.45 Mrs YA finally got a large trout and tucked in on the nest edge. And at 16.15 White EB also received a good size meal from 37. She flew off to eat elsewhere.

So at least one intruder who visited two nests, or two intruders. And another couple of visitors landed on Nest 2 – a pair of pied wagtails who were prospecting the possibility of a nest under the osprey eyrie!

Here are some images from the day.

  1. It looks like a rowdy game of musical nests at a children’s party.
