1980 Walter D. Koenig Malaverpes formicivorus Westgate Hastings Reservation (22 June) trudged on out here (at about 2020) and opened the hole, finding all 4 babies (who looked in good shape) plus noone else. Since they're a little young for this kind of neglect I brought them home and kept them warm all night. 23 June 450. Returned the babies, except for Red-Wn, who unaccountably had some internal abdominal hemorrhaging last night and died. 1000. Came over here to check, finding the 2 big babies dead and the runt fading. I removed all 3, taking the runt home in an attempt to resuscitate him. I am somewhat baffled as to why they should suddenly abandon their nest altogether. In any case, I think this group should be eliminated from all reproductive success calculations, since it seems clear that the lack of 358's leg, rather than any other factor, was the most important cause of the failure here. 30 June Purge: 3 unbanded. Last seen 2 Feb. 1980, gone by 23 Feb-? Disappeared about 12 Feb. ± 2 wks. 14 July 720. 3 birds, #58 hawking from the main sycamore. 1 August 1415. Counted stores: 530. 5 October There are still lots of (old) acorns here; I didn't count them today, however. 9 October 1700. Counted stores: 197; all were old as far as I could tell- 11 October Saw 3" no leg #58 today on my way up to the Arnold. 17 November 930. Saw 358 plus a 2nd bird here while counting stores: 462. I don't know what's wrong here-they have fewer stores now than they did in August! (There are plenty of acorns out here, however). 945. The 2nd bird is a & and is very skittish. I'm now watching.
