Fantastic news!

Nestcam coverage has begun of Nest 1A (where YA and Mrs YA re-located) has revealed they have FOUR healthy chicks.

Balgavies Loch in Scotland has four chicks at a similar looking stage of development but these are the only two known ‘public’ sites in the UK with such a large clutch.

Four eggs are uncommon in the UK and to rear four chicks to fledging even rarer. Let’s hope for success at both sites.

FOUR chicks!

FOUR chicks!

And whilst we were absorbing this news the third egg hatched on Nest 2. Time to be confirmed but the newcomer was mostly out of the shell and stretching up to join the siblings for lunch! It is nearest the nestcam, one sibling is in shadow.

      YA will definitely need to be hunting well the larger they grow but he knows Kielder well and often manages quick catches.

  3. Best news on a good-news day.

    Wow! How fantastic. So delighted for you all. Only a couple of weeks until I visit again. Fingers crossed they all four make it.

    Great news! I’ve been away so this is the first I have seen this. I imagine the people at the fishery (where YA would have come to grief if they had not rescued him several years ago!) would love to hear about this!

    So our local birds with their 4 chicks is not so unique. Why this sudden rush of multiple eggs being laid and successfully hatching ? Let’s hope both nests prosper.
    I wonder if there is any common gene relationship in the parents.

    • joannadailey says:

      It isn’t unique but rare. On four egg Osprey nests it is even rarer for all four to fledge but at both Balgavies and Kielder the hurdle of the first fortnight is over.

    • In the European osprey population, the rate of four-egg clutches appears to be around one instance in a hundred. So we would expect two or three examples to occur in the UK each season. It is a matter of chance that, this year, two of those examples have happened at monitored nest sites, so we know about them.

      There is no scientific evidence that parental inheritance has any effect on clutch size in ospreys. The beginning and end of egg production in female birds is controlled by circulating factors (notably Luteinizing Hormone) in a complex series of endocrine interactions. The average size of an osprey clutch is three, but random variations in the “system”, coupled with external influences, can cause this number to be lower or – very occasionally – higher.
