1981 Walter D. Koenig Melanerpes formicivorus Lambert Hastings Reservation (14 April) 914. δ582 mounted one of the ♀♀; he may even have come close to a successful copulation, but after 4-5s it was interrupted by an intruder, which the ♂ chased. 940. Nets up. Still no sign of δ583! 1000. Intruder: ♂ M / blk-ob Bile/or--blk #566 from Al, chased by δ582 1008. At least 2 ♀ intruders suddenly came in. 1012. Up in the far VO were 3 ♀♀ and the ♂; there is at least some possibility that 3 ub ♀♀ have (are) moved in here! 1015. Leaving for now. Still some intruders. The 3 (4?) birds are mostly just hanging out together. While checking on our way out, it turned out we had a bird in the nut: now ♀646 (another apparent 1st yr bird!). 1215. Caught δ582 in the net. Taking nets down. 1820. Back for voosting. 1900. 3 birds ended up coming, they hung around in the upper VO for ~10m, and then right at the last minute 2 of them (at least) shot down the hill to some totally unknown destination! So no hope of an ambush for now! 22 April 1730. On arrival we flushed a single ub ♀ from the area; she flew down over toward the ridge where everyone often hangs out and stayed there for several minutes with an unbanded ♂! Then we watched up at the main area, where again a pair of unbanded birds came and hung out together! 1750. Going to check around (both birds have left). 1800. Pub back in the main area by herself. 1805. Just flew way off toward (and as far as) South Ravine! Leaving.
