Melanerpes formicivorus
Arnold I
10 March ** GROUP UPDATE **
♂566 disappears 5 Jan 1982 ± 2 weeks
Last seen on 11 Dec 1981. Missing on 27 Jan
♀567 returns to A1 14 Feb ± 2 weeks
Last seen at FA on 27 Jan 1982, definitely booted
out of there on 20 Feb 1982, and comfortably
back at A1 on 9 March.
9 April Counted stores, 1330: 1650 Total
Several A1 birds seen up at KO, plus ♀680 ms seen
in the A1 granary
28 April After seeing birds in the traditional A1 nest hole the
last two days, I opened it up today at 1730 + found
4 eggs, 3 normal and one obvious runt! Unfortunately,
I wasn't able to measure the runt. The hole had been
slightly deepened since last year, and even after a good bit
of sawing on the inside of the hole, I was able to just barely
touch the eggs, I'm sure I'll be able to reach and remove
banding age fledged young. Also, if the runt is left in the
hole after hatching, I might risk trying to salvage it
then. I would guess that this nest is at the same
stage as Black Oak: Hatching ~ 5 May, Banding
maybe 27 or 28 May. Also, 8 May would be a
good day to climb up to the hole to check for hatching.
11 May Checked nest, 3 babies 1 unhatched runt (see nest record)
29 May Banded 3 nestlings, Juvs. 760-762: See capture records
7 June Counted stores, 1630: 1460 Total.
I may have missed a branch on 9 April and undercounted by ~300
