1977 Walter D. Koenig Melanerpes formicivorus MacRoberts Hastings Reservation (17 February) 8) During December, ♂323 (plus his 1st-yr. friend) were still in evidence, though their stores were essentially zero. ♀511 was not seen and may have deserted already, but will be assumed to still be present as long as ♂323 held out. 9) ♂323 and ♀511 abandoned their territory, presumably due to lack of stores, on about 17 January 1977, ± 1 week. 10) Since then, birds here have been wanderers (e.g. ♂314) or potential residents (such as the ♂ub there today). The territory, however, is presently uninhabited. 7 March No birds, no stores. 18 March ♂323 positively identified at up Robertson Creek; see general Melanerpes notes. ♂2nd bird there also. The same individual was almost certainly seen there on 2 February. 2 April 1620. Nobody seems to be up here, as expected. 15 April 940. Several birds here: 1 ub♂ and a ♀ub more or less together in the [Empty] granary; 1-2 other ♀♀ub in the vicinity. At least one landed in the granary and was displaced by the ♀ consorting with the ♂. Both these birds drummed in the tree, the ♀ several times. The ♂ hawked numerous times. 1000. Everyone seems to have split entirely. In any case, several [illegible] birds are obviously interested in the area, and no doubt a couple with move in soon.
