1980 Walter D. Koenig 5 Melanorpes fomicivorus Finch Hastings Reservation (14 July) from the area, is #293. Another bit of indirect evidence is Sandy's observation that #282 was unaccountably upset today, beak-cutting and generally carrying on in an unwholesome manner as though someone near and dear to him were missing. I should add the one bit of contradictory evidence concerning the identity of this bird, which is her molt. All 4 of the primaries on the right wing, #6-9, were brand new and newly molted. This is very early for adults (who should only be about ½ way through their 1st by now - see #123, #621 caught this morning and #519 caught yesterday) and downright amazing, I would think, for a ♀ still busy tending her second nest. Either this girl's molt was unaccountably early - essentially concurrent with her 2nd nest - or a bird more likely to molt earlier is involved. Presumably this would be a 2nd yr bird undergoing his/her 1st contour feather molt, which in this case would have to mean #501. Thus, final determination will have to wait for some further watches at this group. A second obvious question is: how did they die? This is even worse than who they are. The situation contains all the same contradictions involved in so many other apparent depredations of Acom Wdprs (e.g. #485 at Gazebo). Cogent features • include: 1) Feathers in 2 distinct piles on ground, plucked from bodies which were taken elsewhere. 2) Piles located almost directly below active roost holes (they have definitely been roosting here [vide Sandy]).
