1980 Walter D. Koenig Melanerpes formicivorus Warp 5 Hastings Reservation 8 May 1215. Checked around here, finding lots of nice looking trees, but no promising holes. However, there are stoves left here, so they no doubt have a nest somewhere. 9 May 1200. Walked through here, seeing one bird in the granary fly off around the hillside (toward Gate). But otherwise we found no new good looking holes. 17 May 1030. Checked everything I could find here with notably little success. I did recall and check a nice hole in a Black Oak on the ridge toward Velhalla, but I didn't see anything terribly promising there. 4 July Coming up here to check roosting we flushed 3 birds from the hole in the Black Oak, at least one of whom was a baby from the call it made (Ron had seen fledglings here following adults awhile back). Eventually I may get these birds. (Ron is pretty sure there are 2♂♂ and 1♀ here, all unbanded). 23 July Set up an ambush here (at the lower hole in the Black Oak). Ron watched this evening and reported a total of 6 birds (!), 4 of whom roosted in the hole. So, apparently this group consists of 2 adult ♂♂, 1 adult ♀, plus 3 babies from this year. 24 July 630. The ambush was a success, netting 2 adult ♂♂ (8628 and 8630) an adult ♀ (8629) and 1 baby, who had just started her post-juvenal molt and is going to turn into a ♀ (8631). Now all we have to do is find their other hole and get the other 2 babies! [3! see below: apparently they fledged ?4 here] 28 December 900. An ambush at the same hole as before yielded another 4 birds, only one of which (8629) was banded! The others (1♀ and 2♂) were all apparent 1st yr (wearing mainly) and are now #633-635.
