Melanerpes formicivorus
1800
(30 May) Most of the activity was taking place in and around the old
"nest" tree, which they have finally reclaimed, apparently,
from 1500 (the 1500 birds were here, however, but only
in the trees on the knoll side of the 1800 nest tree).
I wasn't able to watch very long, but I nonetheless
identified 4 birds for sure (there may have been more,
but I noticed no others): ① ♀ub; presumably the
breeding ♀ here; this bird was doing most of the chasing.
The bird she was chasing was ② DB/DB/#193 - the
♀ who bred last year here with ♂260 and who I last
saw last July! Amazing! Meanwhile, both the ♂
were here - ③ ♂ LG #476 and ④ ♂ LP-DB/LP
M/LP-DB #347, the
latter of which has clearly been involved in some
shenanigans himself. They appeared to still be amicable
and I noted no chasing between themselves or of/by
them and the other birds. Altogether quite a cache of
interesting birds!
1415. Passed by here again; all quiet this time and no one
in the nest hole.
2 June 930. No one in the nest hole. I bet this nest has failed.
5 June 1900. I finally made it up to the nest, and as I'd suspected
there was nothing in it. There was also no sign of any birds
in the area while I did all this.
2 July With the additions of Ron's observations here in the last
several weeks, I make the following changes:
1) ♀ub. This bird, presumably the one who bred here (see
Nancy's notes for further details), moved here apparently
