Barn Owl monitoring

This morning I started my Barn Owl nestbox monitoring season, and checked boxes near Bet Nir and Gal'on in S Judean Plains together with Re'a. The project there is well established, normally with good owl densities and high box occupancy rates.
However, something happened this year and the situation was very grim, with very few boxes with owls and kestrels today. Most of the boxes had Jackdaws breeding in them, and with the Jackdaws come their parasites - Great Spotted Cuckoo. I was glad to find in one of the boxes these two sweeties - they were very big already and will surely fledge within a few days.

This is Re'a enjoying every minute of nestbox cleaning:
