DuVal, E.H. 2004 Journal Isla Boca Brava, Chiriqui Prov., Panama 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
