Melanerpes formicivorus
School Hill
Hastings Reservation
(21 April)
935. Scratch that. A ♂ is in the tree above the exclosure
and is ♂ Yel/Red #402. He is hawking and gives occasional
Garricks.
950. #402 flew down to lower area. No obvious
chasing has occurred and his Garricks were not acted
upon. Hmm. Is he returning here? If so, why does he
Garrick and act like an intruder? What's his status
with the other 2 birds (886, remember, is presumably his
father or uncle).
1000. Now leaving. This ♂ is pretty interesting. Might
be worth watching roosting to see if 2 (?) birds are
roosting here.
1003. Several questions solved: All 3 of these birds - ♂, ♀, and
♂ Yel/DP #402, are peacefully coexisting in a Valley Oak
down below the exclosure eating catkins. It would appear
as though #402 is rejoining this group as well. Both
interesting! No aggression resulted from this, though each
was several feet away from the others.
24 April 1750. Noone in any holes.
29 April Add: ♀260. Moved as adult 3 April (see notes)
3 May 1130. Checked '77 (etc.) nest hole - bottom ok but no eggs
(Larry reported a bird in here last week).
7 May 1905. Late this evening I came up and shouted at the '77 hole
to no avail. But I did scare a bird from the storage area,
who flew up to the top of the exclosure and then, after
several minutes, returned and roosted in the hole (alone, as best
I could tell).
