1977 Walter D. Koenig 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.
