Hastings Reservation
1 June Ron checked the nest and found 2 eggs; unfortunately he somehow
broke the #2 egg while taking it out.
2 June 1420. Another new egg now (2 in nest, total of 3 laid.)
3 June Ron checked the hole at 930 but still only 2 eggs.
5 June Watched roosting here tonight: 884 roosted in the nest for sure.
6 June 1630. Counted stores: Vally Oak: 150 ? 357. They seem to be
Sycamore: 207
going fast here!
22 June 2000. I missed the chance to be sure, but I am fairly
confident that it was 884 spending the night in the nest
this evening (if not, it was the ?, not 868).
24 June 1630. Checked up on the 1 baby here (Ron has further information
on this nest - in short, only 1 of the 3 eggs hatched). I also
added the remaining baby from Westgate's ill-fated nest, who
is a little emaciated but otherwise quite comparable to the
one that's here (he was bigger overall, but his developing feather
traces are only about 1/6" long - only about 1/2 that of the
baby that belongs here). The rationale for all this is to
replace the 2nd egg which Ron broke, also we get to see about
nestling recognition by adults, as well as to see about
whether the adults here compensate for the 2nd baby by feeding
more. Also, of course, we get to get rid of this last baby from
Westgate. In any case, we'll see what happens.
