For those not familiar with fledging peregrines, they do have a habit of grounding as mentioned earlier in the diary with the juvenile that died in an unfortunate accident. Much depends on the nest area, if there is an adjacent flat area where they can exercise and make short flights, they are usually ok. The weather plays a big part, still windless days are a nightmare, no lift.
The nest sites that are confined are usually the ones that give problems, there simply is not enough room to build and strengthen wing muscles for 4, or even 5 juveniles.
Last year I was lucky, I had a couple low down, on separate sites, but these got back up under there own steam, hunger is a great motivator, if they are too low, the adults will not come down and feed them unfortunately.
On Thursday I was called to a site in London( Fulham&Barnes Peregrines ) , Nathalies site as a juvenile had come down, looking at it when I arrived, it still had 3 or 4 days to go to attain full fledging status, why it had gone we did not know, perhaps an adult had tried to coax it out with prey, or a strong gust of wind. (Looking at the CCTV recording later showed it went of its own accord).

|Checking for injury, she was ok|
Peregrine juveniles like most birds of prey are full of attitude, this one certainly was as it did it best to penetrate my gloves, even as juveniles the strength they display in there talons is considerable, this was a female. A cardboard box had been placed over it to contain it, this also helps to calm it down. The juvenile was taken back up under licence, and then released on a high point near the nest site. The following day the adults found it and all was well.
This bird was in a confined nest area on another site which did not allow much room for exercise, it was a small space even for the 2 juveniles that occupied it.
|Friday was not ideal weather for fledging|
This bird came from the same nest site as the 1st juvenile, it also fledged on the Thursday, it was seen to go on CCTV on Saturday and that was it, gone.
On Saturday late afternoon it was relocated, quite a way down from where it should be, and also not having fed.
On catching it, it was still lively so it was then taken back up to the roof to join its sister, we were hoping that the adults would feed it in the evening.
|Little male, adults found him this morning|

All the juveniles are now getting fed so they should be ok, juveniles 1 and 3 are from Nathalies site, there is a 3rd juvenile in that nest that has not fledged, fingers crossed…..
Glad you were around to help out and the birds are all OK.ReplyDelete
