Percentages

There have been a couple of ‘events’ which both have elements of doubt, hence the title.

First, there is no doubt that Nest 3 male VN, the youngest Kielder juvenile, has fledged! He took his first flight sometime between 06.15 and 08.14 today, and the latter looks 95% likely.

In a short period of recording at 06.00 he jumped and ‘helicoptered’, looking nearly ready to fledge. The next recording starts at 08.00 and he was eating. But soon after he finished he began exercising again which suggested he had not fledged at that point.

A few more jumps across the nest (during which time he was left to get on with it without obstacles like a parent) and then he went onto the far edge. A bit of a wait and suddenly he was off.

He flew around for just short of six minutes. He could be seen against the sky circling the area before he came in to land.

The flight ended with a slight stumble but all was well. So all six juveniles on the three nests are safely airborne and returned, some more safely than others!

The second percentage is a bit lower – we are 90% certain that Blue 2H, the Nest 2 2012 male who has been seen at all three nest sites this year, landed on Nest 1 on Friday at 17.06.

His ring was too blurry to read but his tail feathers and a couple of spots are consistent with 2H from the footage earlier in the season.

The intruder’s behaviour was typically ‘2H bold’ too – he landed with a fish even though Mrs YA was eating at the time.

We haven’t seen an intruding osprey with a ring for some weeks and the last sighting of 2H was on 15 May so evidence he is still interested in forming his own territory at Kielder would be good news indeed. Let’s hope Friday’s male tries his luck again.

    May I congratulate the project on the 30th bird to fledge since that first trio fledged back in 2009 from Nest 1. A huge success over the seven years of Ospreys breeding in Kielder Forrest. (Excuse me if my numbers are wrong).

    I am not sure what my own highlight is maybe Blue 35 producing 6 chicks to date and continuation of colonisation throughout Northern England.

    Hope 2H stays around for many years and becomes Nest 4, 5, 6 whatever that may be but I suppose as a 3 YO is just being a nusance.

    Many thanks for your kind comments, Keith. Your numbers are spot on!

    We hope Blue 35 is the first of many Kielder offspring to play a part in osprey population growth

    Very well done VN. May all youngsters at Kielder be well fed to face the awul torrential rain and high winds. It’s been dreadful down here all day. My heart goes out to youngsters at every nest.
