17 May I wander over here 1500 after Pam had told me of
seeing a nestling looking out of a hole over at CV#2.
Sure enough, I come to the spot Pam described and
found about a 30 day old nestling looking out! Jeez,
that means these guys must have started to lay
eggs on April 3 or so (±4 days, I guess). Pretty
impressive, I must say. The hole would require at least
length of extension ladder (perhaps both), so I'm inclined
not to try this nest, given that fact and the fact that the
young might "fledge" the moment I put the ladder up.
At CV#1, things were better. Found a ♂ looking out
of last years nest hole (opened), flushed him, and heard
nothing, making me think they are at egg stage.
I will check them at a later date.
20 May Climbed up to the hole at CV#1, and to my surprise
I found 2 fairly well along nestlings: Eyes open,
feathers beginning to u-sheath, ~17 days or so?
24 May Banded the two CV#1 nestlings today,
now J727 + J728. I did not take blood,
because neither bird looked especially great. In
particular, J728, the smaller of the two, was
doing some strange panting or producing weird
noises. These two were not as old as I
thought they were now may be 18-19 days
14 June Walkover to CV#2 at 1450 and sure enough,
they have a second nest! It is in the upper (proximal)
hole of two opened nest holes in their blue oak nest
