1976 Walter D. Koenig
Melanerpes formicivorus
New (800)
(16 March) Hastings Reservation
Live oaks on the Haystack knoll above the main storage tree,
and returned several minutes later.
1245. All 4 birds have flown up to the Live Oak slightly up
& on the knoll along the same line as is made by the
2 storage trees. They are apparently sapsucking
up there.
Count: Nest tree: 550 Total: 829
Main tree: 279
I went up to the Live Oak area and was unable to find the
sap area, though I suspect that is what they are doing
up here. I did find a possible roost hole in one of the Live
Oaks, however.
Purge:
jur. #167, last seen 30 Oct. 1975, gone by ~11 December, Disappeared about
20 November ± 2 weeks.
22 April 1640. Watching. In the Main tree are apparently 3 birds,
mostly doing no more than sitting around alert. Identified
were ☺♂LB/W#43 and ☺♀LB-W/8ik#166; The 3rd bird was a
♀ as expected.
1913. ♂166 eating acorn. The tree is entirely shaded, but no one's
made the move to the other (lighted) storage tree.
1945. I'm off. Surely the 3rd bird was #42. (Jespere)
29 April 1010. Watching. ☺♂LB/W#43 in Main tree.
1015. ☺♀#42 in nest tree; a strange, but banded ♀ over in old tree
toward Gate; #44 flew to nest tree, landing wake, but
was immediately chased violently by a 3rd bird, identity
unknown. Meanwhile, 1-2 others in main tree. Wow.
