Melanerpes formicivorus
Warp 5
4 June I wander around uphere after seeing birds here from Road 1.
No nests found, but a couple of good-looking holes in
a big Black Oak SE of the granary, in the canyon just
"downstream" from Valhalla canyon.
8 June Watching from PO Hill, a see a bird feeding a fledgling
in the granary! Looks like theyve already done it.
23 July Roosting after Walter sets ambush. 4 birds roost in the lower
Black Oak hole. At one time, 5 were in, but one flew out
late. At least -6 birds in the group, however.
24 July Successful Ambush! 4 birds (2 ad σ, 1 ad ?, 1 Juv molting
into ? (?) plumage. At least 2 birds (I suspect both juv niles)
still remain.
