Melanerpes formicivorus
Arnold 3
Hastings Reservation
(19 April) sitting for several minutes they all headed abruptly
for the sap area at UA2. No kidding - the cohesion
in this flock of birds is really odd - it's exactly like
a small flock of finches.
1540. Sitting in tree just below storage area: ①,②,
③♂120
④♂ub#360
⑤♀255 plus a 6th bird still (a♂).
All just sitting, all within 10 ft of each other in the tree.
⑥♂DB/light#123 here also. Now he and several
others are in the storage tree eating acorns.
1550. ④♂wn/DB-w#126 seen in tree above storage tree
with several of the others.
1600. Birds have all disappeared again. Time to go. No
sign of interest in holes (but where's the 2nd♀?). I'll
check them before moving on.
1600. While getting out, the birds all flew to the upper part
of UA2. I walked over there, and ended up flushing
♂RRR#205 plus another bird from the UA2 nest area!
(The others had returned to A3). The general idea:
[illegible]
Arnold field
The 2 birds (♂RRR+other [♀128?]) flushed across the
canyon, like ♀128 always has in the past.
