25 Mar 04 - Weather was hot and dry, again,
with the North wind blowing [illegible] until
mid-afternoon and then suddenly stopping. The
manakin action picked up dramatically during this
reprieve.
I did watches at FBE2, GUL2, TCJ5, BR12,
CCL1, +SBE2. WAY seems to be gone from
FBE2 entirely - YVB(DM) is acting like the local
beta, with RVV still present (?). Before the
watch, I saw 4 redcaps (3 banded, 1 ) dancing
on FBE3 dp, with an vvb CB occasionally joining in.
The RC's were doing Tbx, v excitedly doing the
back-and-forth move when another RC flew
over. One practiced the swoop & bounce moves
as well, with no one particularly paying attention
to him. =>Not aggressive displays because often
not directed AT another bird. I do think
that these behaviors are best described as
practice or play. I set the video camera
here in the afternoon to see if I could
record any RC-RC dancing. The watch at
GUL2 was ill-advised due to high winds, +
I stopped after 1/2 hour. TCJ5 was similarly
quiet, though less windy. Several individuals
were seen feeding on Micronia fovit.
At BR12 I eventually saw BOW, but
