Melanerpes formicivorus
Plague
HNHR
6 December Caught j983 in an ambush in the nest hole, but
everyone else appears to be roosting in some unknown
hole somewhere.
1985
19 January 1130. Counted stores:
Plague tree: 1390
2° tree 122
Tel pole 370 (mostly in styrofoam block)
Barn 45
Total 192.7
30 March 1630. Watching at Plague. Saw 8521, 8721, who
mounted each other. 3♀-♂? or /m #973. One of the
babies: 4♀ M/LG/WN #984.
1645. Saw another mounting between the 2 88's.
31 March 930. 8♂/Dk:: #723 flycatching in the Sycamores by the
bridge.
April 800. Big doings at Plague - several intruders, but apparently
#973 is still here so no vacancy. My observations (Philip &
Missy here too):
810. (♂) #723 chases off ♂ up by Cabin. 5+ birds in Plague tree.
819. 2 or 3 intruders in main area; only ub ♂ seen so far.
②#984 here. ③#8521. ④#8721. ⑤#973. • #983 here also but
no PID on sex yet. Philip reports he's a ♂.
Philip has seen 2 ub ♂ here. I'd guess 2-3 birds
intruding at most. But, with no vacancy and the whole group
of 6 against them, I wouldn't give them much of a chance.
