Acorn Woodpecker
Low Hay
(27 March) Instead of seeing 8721, 8723, ad 9650, I see two
completely different birds! They seem to be
8571 Blue-Black/Blue (pretty sure) and a ♀
Lbn-Dorn/M
whose bands I read as Lbn-Dorn/White (or something
like that: sure of the light-dark split, pretty sure of
white, certain of metal). They seem at home and
well established. What's going on? Interesting
that 8571 would come to Low Hay when his old
haunts of Hay Blom + Gazebo appear to be available
1350. Now 9650 shows up Blue-Black/M, leading
to the suspicion that the other ♀ is her immigration,
partner 9649 (or 648?). I will have to check.
No activity on the grany lins, but Front only 75 acorns
remaining.
5 April Here 1200, 8571 M /Blue-Black, plus a
♀ which I am almost certain is unbanded. Bom
sit in the grany ~10 min, then fly off toward
Hay Blom. (Philip has seen these birds, Loc at rear 8571)
filching acorns from Hay Blom.
13 June ** GROUP UPDATE
① 8571 founds Low Hay 27 March 1984
② 9604 9711 move to Low Hay 9 April 1984
These 3 birds controlled Low Hay + Hay Blom
until 11 May, forced to leave by 9524, 2 ♂NB)
③ 8571, 9604 9711 move to Hay Blom 11 May 1984
④ 9524 ♂NB, ♂NB (1992, 1993) move to Low Hay 11 May 1984
♂NB may be same as 83 ♂NB
