Melanerpes formicivorus
Road 1
Hastings Reservation
(10 February) 1125. Several birds at each of the 2 x spots now. No wing-streamered
birds seen. Birds are apparently sapsucking in a Live Oak
in the bottom of the gulch here (+ on map).
1145. I moved down slightly to scare off the birds on the knoll
that I could not see below me (⊙ on map). I could not tell
what the birds had been doing; they were in a patch of young
Blue Oaks and flushed first to a large Live Oak below (if I
were forced to guess, I'd say they were probably sapsucking, but
I could see very little resembling sap holes, and in any case,
what would douglasii be doing with its sap running this time of year?)
The birds, ☺ at least 4-5 of them, eventually flushed across
the road and then all went up the ridge of Poison Oak Hill
about 100 meters before stopping in a Live Oak there. In the group
I saw all 4 of the early juveniles (180, 181, 182, 183); 181
had been definitely come from the area where I'd just flushed
birds. I did not see any other wing-streamered birds:

1200. Now I'm lower, and above me again several birds
are greeting (about where the ☺ is). A chase occurs, then
a minute later ♀ PRW is still in the tree where the chase occurred
and then flies down rather than up to the other calling
