(1 May) The bad news is that I checked the hole at
1415 and found only 7 eggs! Egg #5 has
disappeared, for reasons unknown. Damaged? House
wren? Snake? Who knows. Egg ⑤ was apparently
one of ③883's, so the current skew is 5-2. What's
more, egg ③, also of ③883 has a slight chick in it,
meaning it may not hatch. Could be a strong
skew in young fledged here.
8 May Checked nest, 1830; Hatching, see nest record.
10 May Checked nest, 1030: 3 nestlings, plus egg ⑦ that
failed to hatch. Found hatching fragments of eggs ① or
④, leading me to suspect final skew is 3-0 in
favor of ②269. One of the 3 nestlings marked with
blue sharpie on 8 May was missing.
1 June 1630, Banded ⑥ a disappointing 1 nestling
5 June Granary census, 1415-1615, o-back. Routine. Birds
doing a bit of sap-sucking from the Live Oak behind the
1° granary. ②269, ③883, ④86, ⑤78, ⑤79, ⑤80,
⑥72 all seen well. Only ②294 + ⑧804 missing.
6 June Granary census, 0810-1010; Same birds as yesterday
plus ⑧804 seen too meaning only ②294 is missing. Best
thing was that a ~3 foot gopher snake was in the middle
stubs of the primary granary, being mobbed fairly vigorously
by several birds, especially ④86, until the snake
took refuge in a hole. The breeding ①Q ad ①helpers
also mobbed with some enthusiasm. Though ⑤78 + ⑧804
were around, they didn't do much other than approach a few
times.
