Melanerpes formicivorus
Blom 2
4 June Opened the nest in the Valley Oak that Walter + I independently
discovered yesterday & today: 4 eggs!
22 July Roosting, and I see 2 birds roost in the hole
just above the next hole. An ambush may
be in order.
1 Aug I set a ambush (first solo effort). 2 birds roost, but
I saw a third bird flying around, so may be 3 in the group
2 Aug NO dice! flap doesn't close properly. Such is life.
26 Aug Try roosting here again. I flush 2 birds out of the
same hole (above next hole). But 3 go back in later.
Definitely 3 birds in this group.
29 Aug Successful ambush here! Very confusing roosting
on 28 Aug, but I saw at least 3 & perhaps 4
birds go in. This morning I bagged 4 birds!
All banded, and all from Gazebo, M516
J (M)569, J (M)571, and J (M)572. J572
stayed in the hole a full hour past everybody
else (!) only emerging when I reclimbed to bring the bag
down. Questions: 1 Have these 4 M really
moved here, or has Blom 2 been abandoned after
failed nesting this spring, and Gazebo birds are just
hanging out & roosting here, former possibility
supported by the
fact that all M including juveniles, and they looked
like they were pretty settled here. I'll have to watch
at Gazebo, 2 if they have moved here, was it to replace
a dead male, or occupation of an abandoned territory?
3 Do they have a female? while processing others where is she roosting?
