1982 R.L. Munne
Melanerpes formicivorus
Finch
18 April Back by at 1750, Nobody in the 1980 hole this time.
24 April A quick watch here, 1500-1530. Obviously status quo.
♂66, ♂282, ♂501, ♂540, ♂541, ♂542, ♂543,
♀614, ♂616 all see well. No sign of a new ♀
No interest in any holes.
4 May Pa- reports ♂542 near Blom 1, Flying
Toward Corral Viejo.
7 May Sitting in the truck here, I see a bird make a very
brief entrance into a hole at the top of the sycamore hole
stub. Doesn't look serious, but I will have to be
alert here.
27 May Whoa, as I drive up here at 1030, 2 birds were in the
1980 nest hole. One flew out, but the other stayed in and
looked out,
Back at 1155 for another look, I say "hello", and a
bird looks out then flies off. If this keeps up I will
have to check that hole.
29 May 1700, again a bird looking out of the 1980 nest
hole. I return with Alan + the extension ladder
at 1800. I climb up + find 4 eggs, 3 normal
(see nest record)
+ I run, about 4-5 days incubated, I would guess,
Which ♀ (or ♀♀) laid these? Alan watched here
last week and saw only the 3 "helper" ♀♀, no
new ♀ at all. We probably had rampant inbreeding, but
there is no way we'll ever figure out who did what.
Watching the nest will probably help, but I can't
think of how it could completely resolve things.
