Melanerpes formicivorus
Corral Viejo Canyon
Hastings Reservation
5 Jan
I come over here, 1100, and try to watch OK Corral
in the hopes of finding some banded birds. 1200, No
such luck. Simultaneously in the granary area I see
5 unbanded ♀♀ and 1 unbanded ♂! Two or more
of the ♀♀ look like first year birds (dark eye, short
bill). This may be all the birds in the group.
7 April
In light of CU#2's incredibly early nest last year,
I think it a good idea to walk over here at 1020 and
say hello to the holes. Nobody in last years first
nest, but in the "holey" Blue Oak above the
ganary, I flush a woodpocket out of a "new" hole
in a stub on the uphill side of the tree. Wasn't
sure which hole, because there were several in the
stub, but it bears further watching.
26 April
A tour of Corral Viejo groups, 1730-1830, produces the
following info.
① Flushed birds out of the 1982 nest holes at both
CU#1 + CUGra-de
② Flushed a ♀NB out of the roost hole where we ambushed
at OK Corral
③ Nothing at Blom 3 and (surprisingly) CU#2.
Will have to check here again to see if we have nests here
28 April
Opened the hole at CV Grande (after making a deeper cut)
and found 5 Eggs (including 1 partially-buried runt) ~4 days incubation
meaning 28 May would be a good landing date. Did not flush
anybody out of the hole at CU#1, but I did at OK Corral,
meaning that they must certainly have a nest.
