Melanerpes formicivorus
Chonge Hastings Reservation
26 January 1600. Counted stores: 820; and removed a sample of
40 acorns.
18 February 930. Watching.
1030. To nobody's surprise, things are 100% quiet down here. I did
hear some calls up and over on Red Hill at one point, however,
and I saw one bird flying around across the gulch.
I do see 2 AtW sitting in one of the tall trees over on
the side of Buckeye Hill over toward the bend in Matrone Canyon.
22 February Watched roosting way over at the tree with the 2
holes over on Buckeye, where at least 3 birds came to
roost.
16 March 1100. Counted stores: 620. No birds seen in the area.
21 April 1415. Walked over noting: 1) stores do remain, yet in the granary
2) a bird was in a new hole in the sycamore, just below
where I trapped them all in December '75; 3) there were
several birds over in the area around the roost hole up on
Buckeye Hill, including 1 bird sitting just below the main
hole when I first looked, but none was in the hole
when I walked over and checked.
Returned at dusk, when apparently 1) nobody roosted over
on Buckeye Hill 2) most of the group roosted in the main storage tree
and 3) very possibly 1 bird roosted over in the sycamore, lending
some credence to the possibility of there being a nest there.
22 April 1030. Now there is a bird in both holes in the sycamore;
best I can tell a ♀ in the lower and a ♂ in the upper.
Lower hole was opened (from the back side) and had 5
fresh, good eggs.
