DuVal, E. H. 2000 Journal Isla Boca Brava, Chirigui Prov., Panama June 2000 Heavy rain after 1:30pm 45 min EHD netted at TS 1 and captured the unbDM on the first net run (only manakin captured). He is now banded RPY. He was not caught badly - I only had to untangle the feathers of one really badly caught wing using Mark's technique of pulling the pomerica through the tight net to relieve tension (see opposite page). But after I finished taking blood I noticed that his right side was starting to inflate with the characteristic pepper-air sac symptoms: the skin was lifted well off the breast muscle, & the bubble was spreading. When released he was unable to fly (perhaps because his body was distended under that wing?). I placed him on a branch ~12m from the banding station. 40 min later he was perched a few feet away, barely off the ground. At 11:00 I was unable to find him. This is the 4th or 5th bird this year that has had this problem, and I'm still not sure what causes
