Melanerpes formicivorus
Upper Arnold 2
Hastings Reservation
(17 June) certainly could have been inflicted post mortem, as it were.
Its eyes were just opening and it was at the stage where
the 10 were just not quite poking through the skin. Obviously
this bodes poorly for this group; but with no stores at all it's
pretty amazing they made it as far as they did. The carcass
was kept so I can look at it more carefully later on.
12 July
930. Nobody here in passing.
30 July
1800. One Bird (a banded ♀) flew over here from A3; otherwise
none seen here.
1 August
♂ 126 seen at the Arnold Spring this morning by Pam.
14 August
4 Birds seen in the vicinity in passing, but none were
identified.
20 August
1210. ♀♀ 289 an 290 (2nd yr ♀♀ from A3) seen in the nest
tree here.
18 September
♂ 123 seen by Pam at the Arnold Spring this morning.
24 September
1145. 1♂ and ♀ DB-WR(w)/DB #290 seen here. There are definitely
at least 2 newly-stored acorns here in the granary.
30 September
Still only a bare minimum of new acorns stored here (≈3 or 4)
8 October
Still essentially no acorns stores here, but 1 bird did flush from
the granary when I approached.
24 October
1015. Found 3 stored acorns; hardly enough to convince me there's
a group here. The active presence of all the ♂♂ here down at LA2
makes me even more suspicious. See LA2 notes.
14 November
Still no stored acorns or group. All the ♂♂ are down at LA2,
coming up this way only to pick acorns.
The top of the nest tree here has fallen w/in the last 3 weeks. The
nest hole is intact, however.
