Melanerpes formicivorus

Lower Haystack Hastings Reservation
26 April Start 0630, nobody around. 0750, a pretty boring watch overall.
Again, ♂307, ♀515, ♂461 all here, not doing much, but hiding
is granary very well. Again, ♂307 + ♀515 seem to be
together more, but I lack good data (didn't have
them in sight often enough). At one point, a ♀NB intruder
chased (without a lot of élan) by ♀515. Going to check hole.
Whoops, with another ♀515 chase of ♀NB.
30 April Start watch 1610. ♂307 + ♀515 here. ♀515 chases (without
a great deal of enthusiasm) a ♀NB intruder from the granary.
1730, these guys still don't look very interested in nesting
any time soon. Both birds fooled around in the granary
most of the time I was here. Very difficult to watch,
though.
1 May Trying again in a bowling wind 0700. ♀515 huddled in the granary,
near the "hole" I thought I flushed a bird from yesterday!
Oh No! 711 a bird heads out there, flies off. 711.50,
♀515 enters. The ultimate pisser! Incubating already. Back
at 1630, a struggle to get into the nest, but 3 eggs
2 May Another watch here. high point was ♀524
intruding here, chased (presumably) by ♀515. ♀515 very
suspicious of opened nest. She is indeed a wiley one.
Seemed like 4 birds here for awhile, perhaps ♂511 back
from his wanderings.
Roosting was pretty neat! I think ♀515 was in the hole
when ♂307 came to the hole. The bird in was reluctant to
leave, until ♂307 pecked at it a few times! Anyway
♂307 roosted alone!
