Melanerpes fornicivorus
Gate
Hastings Reservation
28 April
600. Nothing in hole (Ron put a fake egg in here yesterday).
I put in another fake egg, set up the movie camera
(using time lapse, 1 frame/s), and got ready to try for pictures
of egg tossing.
620. Immediately 3 birds came to the granary, hung around
briefly, and then flew off together (not in a tight pack but
definitely interested in one another) across the road.
730. Changed film. Just before I went up the 3 birds had been
(sure-) sitting together atop the tree. First the ♀ flew off, followed about
a second later by 8626, and then 2s after that by the 2nd ♂
(8627, presumably).
900. Giving up. Removed the egg.
3 May
630. 3 Birds in the hole, but still no egg; put in a fake one to
try one last time to get a picture.
720. At least 2 intruders around, being soundly chased.
4 May
Birds in the hole at least twice today. Surely they've finally laid!
9 May
Watched roosting: the ♂ came barrel-ling in and did
not really give me much time, but I think it was
3LP/DR #627. However, I wouldn't call that for sure
until I watch again.
(The birds do have a nest here - see Ron's notes.)
25 May
1900. Checked the nest - 3 babies.
1940. A positive ID at roosting tonight: 8627 spent
the night in the nest.
26 May
1940. 8627 for sure roosted in the nest again tonight.
6 June
900. Banded and bled the 3 babies (a little early, but
the PRBO class needed to see something) as #684-686.
