Melanerpes formicivorus
Westgate Hastings Reservation
(8 January) Thus, whether or not 8532 is new, it would appear as
though at least 1 new 8 joined this group while its
prior 8 (858) remains intact (though crippled).
→ Moved here as adult 28 December. [Note that I'm
skipping the intermediate period when this bird
was unbanded—a minor discrepancy, but still one which
should be kept in mind.]
20 January 1450. Garricks, chases, and generally high activity here
among at least several birds. Watching. ① 8ub.
At least 1 8 Garricking almost continuously. Activity all
concentrated in Gate Sycamore over to the flat across
the creek; nothing in Wiate tree. ② 8 B12-Y21/M #519 here,
also garricking. Looks like her position may be on the line.
Two birds in particular (the 88?) are really after each other.
1528. Maybe not. 2 ub 8 together at one end of the tree. 8519
here also. Still many garricks by somebody. Some drumming.
A 8 is doing some of the chasing. I did see a banded 8 (probably
8532) very briefly.
1514. 8519 is one of the bird garricking and may be doing most of
the chasing:
1520. ③ 8 noleg #56 is over eating an acorn in the Wiate
Sycamore by himself; as before, not taking part in things.
1525. All much quieter now.
1535. This time it looked like 8ub was doing the chasing (!). Now
8ub (garricking) and 8ub sitting together in Gate sycamore.
1539. 8ub is the chaser. I can't confirm that 8519 is the chaser, though.
Still no stores here. Leaving for now. Try again tomorrow for sure.
