Melanerpes formicivorus
Westgate Hastings Reservation
23 Feb Start watch from Live Oak near gate on SW side
of Road, 16/0 hrs. Unbanded ♀ (#574),
Plus ♂ #58 M/Light green. It also saw a
♂ beg from #58. Could only see that bands
were very dark, probably (?) ♂ 467 D Green/LG-DG?
♂#58 + ♂ #258 BP-W/M sapsucking in
blue oak behind sycamore west of gate sycamore
end 1750
25 Feb Start watch 0730. Four birds seen, unbanded ♂,
unbanded ♀, ♂ #58 L Green/L Green, Metal/L Green,
and ♂258 BPink-white/Orange, B Pink-White/Metal.
Activity was concentrated in sap oak behind sycamore
granary west of the gate sycamore. I also saw
what I interpret to be submissive behavior,
begging-like "Mickey-Mouse" calls in the presence of
another bird. The results were thus
dom ♂ 58 ♀ 574 submissive ♂238 ♂521
♂58 - didn't see it 5 3 8
♀574 no see - didn't see it 1 1
♂238 sibs? unbande outside?
see no see - didn't see it 0
⊙521 no see - 0
Sort of interesting results. I'll have to check group
history, and see what MacRoberts says about Mickey
Mouse call. Interesting that ♂521 gave cull when ♀574
landed in sap tree. Never heard ♂58 call, although he
was frequently intree with ♂238, and to a lesser extent ♂521
