!April! After an unsuccessful ambush here last night (the birds
roosted elsewhere, somewhere), I came here ~1015 and set
up a net in the granary. With a stuffed male perched
indelicate ly in the tree and a tape of the a power struggle,
the birds were here immediately. In fact, the tape apparently
drew 2±3 intruders as well! The residents were 4:
♂768, ♀945, ♂69[5194], and an ♂6 ♂ (!) This was
a dilemma. The ♂6 ♂ was quite in the thick of things
and eventually got himself caught in the net and
was banded as #988. He was possibly a juvenile: he had
2 small tailspots on one outer rectrix, he was molting a
bit of his crown & some body feathers, his primaries were
sort of blunt at best, his wing was shortish, and his
wings were in pretty good shape-not too worn. Thus,
of the likely scenarios, the most probable would seem
to be that we missed a fall nest here and that he
is a helper from it. Alternatives exist, but it seems
unlikely that he would just join a group with an
established ♂.
Unfortunately, ♂769 is apparently gone; thus, this group
would no longer appear to be a good candidate for
a temporary ♂ removal. The tape eventually ran
down and no one else was coming too close to the net,
so we left ~130D.
8 April 1130. ♂ in hole. 1430. Back to check hole. Nothing yet.
