1976 Walter D. Koenig
Melanerpes formicivorus
Chonge Hastings Reservation
(12 May)
Add:
♂402. Moved to Chonge 0 March 1976, age unknown.
♀403. " " " "
Both these birds were not present 12 December 1975,
but were present 12 May. Most likely their move
was more recent than March.
19 May
1215. Nobody at all in any of the holes here that I know of.
1230. Watching from hide. No birds (AW) around at all.
1245. Still zilch here, but some calling heard across canyon.
1251. Proof! 5 birds (4♂, 1♀, inc. Rub) showed up together in
the sycamore roost tree.
1300. ♂234 there also (♂? / wh-)
1303. 2 brief mountings took place among birds sitting very
near each other in the sycamore: one ♂ on ♂, other ♂ on ♀[ub]
1315. 2 birds out of the 4 just flew down into the sycamore.
I'm going to go check -
21 May
900-1000. Started by checking the holes on Red Hill side,
then went over to Buckeye to check out the birds' favorite
areas there. The area over on Buckeye Hill is very
interesting - mostly young Quercus douglasii, 2-6" in diameter,
spaced 10-20 ft. apart. Occasional large Blue Oaks
occur in groups of 2-4 in several spots, and it is here
that the AW sit and one finds Magpies foraging. Several
AW were over here, but I found no likely holes, nor
any storage areas. By the time I sat down several
birds were back around the sycamore on the Red Hill side,
however, where I think they will nest eventually.
