1978 Walter D. Koenig Melanerpes fomiceivorus Lower Haystack Hastings Reservation (24 June) Second, the compilation for the watch is on the back of p.7. Thirdly, a very unexpected visit occurred at 1935, when ♀ (La/Mh) #391, who I'd previously given up as lost, appeared at the hole. She landed apparently without any food and did not feed. After about 5 seconds a second bird landed nearby, #391 began to move from the hole, and at that point was actually pecked several times [illegible] in an attack by the 2nd bird, who I believe was ♀170. In any case, ♂307 then fed at the hole while [♀170] left and ♀391 moved to the top of the limb, where she sat for >15 seconds un molested until she flew off. From these events I conclude the following: 1) ♀391 (lives) 2) she is having essentially nothing to do with the nest, and 3) this may it part be due to [illegible] hostility toward her on the part of ♀170, for unknown and possibly unfathomable reasons. Thus this unique group is composed of 5 birds - all former progeny- on this territory: 1♀ from 1975, 2♂'s from 1976, and a ♂+♀ from 1977. 25 June Watched the nest from 715-1045; see compilation on back. No sign of #391 today. Purge: ♀16 (Yellowish right leg). This bird, [illegible] apparently the same ♀ as here since at least 1975, was seen 25 May 1977, 4 July 1977, and lastly in 29 August 1977. She was possibly seen on 10 October 1977. She was then missed on 25 Oct 1977 and then on 13 Feb. 1978. For [illegible] entropy's sake I'll assume the latter as thus give her a Disappeared About 11 December 1977 ± 2 months. 27 July 840. watching. 925. An ub♀ (intruder, presumably) was here briefly.
