Melanerpes formicivorus
Plague
(21 April) through roosting. Roosting was rather strange. A lot of single
birds flying around, no mountings or "pairs" or "trios" seen.
One bird roosted late in the utility pole near the Plague tree.
While waiting for roosting, I searched the Branch of the 2°
tree where Byron found the egg 10 days ago, But I saw
nothing that looked like egg remains.
22 April Start 0630. Watching nest hole in Buckeye canyon from
top of Adobe Hill,
0830 Nothing has happened. 2 birds flycatching around
the summit of Adobe, but nobody's gone near the canyon holes
Now watching 1° area from W side of Adobe.
0900, the birds (of course) fly over to the Buckeye canyon
area. I go back there, lots of birds milling around. $521
looked in the nest hole a very long time (10-15 minutes) but
never entered. Finally, at 0930, I see a bird leave
the hole, and a Fetter. Never knew when first bird entered. They
definitely seemed bothered by the hole being opened.
1000, I go to check hole, flushing a bird out. Beggs now,
the new one marked #3+ returned. Probably the work of
correct! 9494: 25.3 x 19.1 (I should rereasure length. Not sure I
checked 24 April remember it correctly). Anyway, is 9496 taking the day off,
or was she freaked out enough to lay in the 2° tree? Actually,
I think she was the bird I flushed when I went to check the
nest. Since 3473 was not around (Laws) I doubt it was 9496.
End 1030. Checked 2° tree hole 1700 hrs. Empty + wet!
23 April Nest check 1100: 2 new eggs, marked #4 + #5. Unfortunately,
I forgot to bring the calipers, so I'll have to measure the
