Melanerpes formicivorus
Road 1
Hastings Reservation
3 September While walking along the road this afternoon I came
across 2 (!) roadkills from this group: ♂577 and
♀806 (just molting to a ♂). The former was fresh and
not very near the latter, who was a day or 2 old.
Bummer days for this group!
1 November 1145. ♂269 seen here while counting stores:
Main tree: 1429 (this tree lost 1 large limb last year
with at least 1000 holes)
Sycamore: 1053 (this tree has accumulated at least 1000
holes in the past couple of years)
Total: 2482
1983
10 January 1330. Counted stores: Main tree: 3040
Sycamore: 2275
5315.
Took a sample of 50 acorns from the Main tree.
9 April 745. Watching the nest hole (no known activity as yet).
830. Climbed up and checked: no eggs; the hole looks like it's still
being worked on.
17 April 615. Arrived. ♂ looking out of hole. Both ♂♀ there! One with distinct
mustache leaves ~620. Other (w/o mustache) stays another 5 min,
heaving out a billfall of sawdust at one point. After both are
gone, I check hole - empty, lots of sawdust in cotton, some of which
I take out. Back watching at 638. Getting close!
810. Leaving. None ever returned. (A House Wren was inside the hole
for a few minutes, however.)
20 April 610. Watching nest - ♂ flushed from hole. (Ron had egg-tossing)
yesterday.
