Chick is back in Selkirk at the nestsite and we are keeping an eye on the site to make sure the adults accept him back without problems. Its purely preventative, we haven't ever had problems with parents accepting a rehabbed chick so no reason to think there might be one here, but we want to make sure since neither of the parents were at the site when we dropped the chick off. Chick had had a meal in the morning (quail of course) and we put him somewhere safe at the nestsite, so his immediate needs (food, water and safety) were fulfilled.
The chick is male (as you have guessed
and small for a male but given that Ty isn't big and nor does it look like Paris is either, not really surprising. Very aggressive, didn't like Lisa and most certainly didn't like me during the banding. Was happy enough to sit freely on my hand during his release so he's an interesting little terror. We've named him Daer. Lord Daer is the title given to the heirs of the Lords of Selkirk, so as a son of Selkirk it seemed appropriate to give him this name - particularly in the year of the 200th anniversary of the Selkirk Settlement and (hopefully) the first year of peregrine settlement in Selkirk.
A friend of mine took some photos at the banding (I had my hands full) and I'll post them in the next couple of days.
