Melanerpes formicivorus
Knoll Set
29 Jan I must finally acknowledge the existence of this group,
even though they have no granary, as far as I can
tell. Also, I successfully ambushed here in the old hole
in the sycamore below the Y, catching 8564 and an
unbanded 9 which became 9715. 9715 seemed extremely
weak when I let her go, feebly flying to a willow. She
did fly out of there more strongly after a while, so I hope
she'll be OK
31 Jan 1500, Alan + I saw away many of the branches that have
overgrown the old Pump artificial granary branches, and install
about 35 mixed Valley + Live Oak acorns. A little experiment
to see if we can get the knoll birds interested in the Pump
area. We also install a fallen Gate branch w/ ~50 acorns and ~
100 usable holes, to sweeten the pot. We saw 3 birds
around the Knoll and lower sycamore, so everyone should
be around.
1 Feb 1420, Quick results! I walk back here and find 3 birds in the
Pump granary! 9715, 8564 here for sure! Working ucorns!
Moving them around! 8564 even shagged a jay out of the granary
Also a third bird I saw as 9 Dpkr/m, probably 9193.
She was here only briefly. 9 NB not around at the moment.
18 Feb A quick look here, 1700, I find 8564, 9715 Lgnc-DBlue/M
and a bird that I thought was 9 but read as Yellow/Blackt
(8561?). However, it looks like the birds are now totally
ignoring the Pump granary. All the acorns were gone as of ~
10 Feb, and I haven't seen the birds there since 1 Feb
They are back to hanging around the knoll.
