1995 1996 Walter D Koenig Melanerpes formicivorus CV2 HNHR 12 April 1600. A modest power struggle going on here! About 10 birds or so and a lot of activity. ①♂Dg/m #2231 ②♀ yel/LB #2107 ③♂ Dg/M Red/led #2418 ④♀ yel/yel #2416 ⑤♀ M/MV #2420 ⑥♂ M/Red #1372. Let me revise my estimate to 15 birds! 1620. Well, I have to go. But with ♂1372 here, this presumably is over a ♀ vacancy - but with 3 ♀♀ helpers, presumably filling the vacancy won't be easy! This is actually quite a good show! Hope it lasts through next week! 13 April 1300. Finally made it back here to set nets (I trained this morning) and it's all quiet! Maybe it's over already? By the way, there are lots of acorns still here. 1996 10 April No one in any holes, but some stones remaining. 17 June 1500. Finally - a nest! New hole in the granary itself. 3 eggs, incubated. 1 measured 24.6 x 20.1. There are (possibly) a few intact acorns left here, but not very many! 25 June 1545. 2 kids; 1 weighed 24 g ≈ 6 do (EHD = 19 June) 8 July 1230. Banded and bled the 2 kids. 15 July 1330. Transplanted the 2 avian kids here; at least one of the other 2 still fine. 12 August 3 dead kids in the nest - ♂ #2710, 2711, ♀ 2712. Only ♀2709 potentially made it.
