Eurasian Kestrel - Netherlands / Beleef de Lente

WOW!!!
I'm going to have to go and check the site again.  Thanks for the update!

birdcamfan:
Believe it or not, the doves moved back into this nest box a few weeks ago and are incubating. Hopefully there will be at least one successful nest (even if they are not kestrels) at this site this year.

birdcamfan:
Interesting post today. The translation is difficult but it seems that they found a male kestrel that they suspect disappeared from this nest a few weeks ago. It was picked up about 2 km away from the nest box by the "animal ambulance" but succumbed to its injuries. They report that there is another kestrel nest about 1 km from this nest box so perhaps a territorial dispute?? They think it is too late for the female to start another nest this year.

birdcamfan:
The dove was sitting on the Kestrel eggs last night but they have been sitting there exposed most of the time. I expect  this has an impact on their viability. I wonder if seeing these eggs in the nest will affect her hormones and her fertility? She seems motivated to incubate them at least part of the time.

The Peregrine Chick:
I don't believe the doves will remove, I have found pigeon nests with old eggs in them ...
As for the doves incubating them, I have no idea.  I guess it could happen ... cowbirds lay eggs in other birds' nests and then abandon them to nest's owner to raise - and since the cowbird chicks grow so fast, they tend to take all the food and the legitimate chicks don't stand a chance.
