and 9524
M / Lots of sapsucking from
that same Blue Oak on the E edge of the field
3 April Stark 1320. 1530, Don~ 9602 pecked hard at 9604.
→ good! 1600 Complete census, 886, 8402, 9260, 9523, 9524
9602, 9604 all seen (in fact, all 7 birds in view at once
together at one point). These guys are no threat to nest
in the immediate future. 8402 spent a long time
camped out in the next Sap tree, with 9260 in the grassy
area. Lots of action in the sap tree (see foraging data,
plus 3 C Hawks early. End
4 April 9523 seen intruding at Low Hay (see LH notes)
23 April Nest check in the "newest" hole in the broken stub. 1000,
5 eggs, I'm sorry to report. Too late I thought
about getting these guys for a fake egg removal + perhaps
photo. A bird flew out of the hole as I approached, so
I suspect incubation underway.
24 April Up here at 1730, 9504 Red-wnt/B1K + I think 9602
in the middle enclosure tree. Walter saw 9504 garricking
constantly at Low Hay. Confirm 9602. Both seem to be
bud-catchin' eating + leaf-back gleaning in the tree. [illegible]
Oddly, they are constantly giving soft karrits. Rather strange.
Not being chased. Anyway, I would think that their
chances of staying (allowed to stay?) at Low Hay are nil.
27 April Roosting, a 8 in the hole when I arrived, stayed. I'm
pretty sure it was 8402 (round head, short bill, double
mustache right side) but I'll have to watch again there
to make sure.
