LL Wolf 1963 Amphila munichrasti August 14 3 mi E Telurantepec, Oaxaca ♂ singing from ½ way up in 10 foot liguan. Then to top of adjacnt 15 foot tree to sing. Another started singing to west. The 1st flew in that direction + 2nd flew to east. Out in top of nearly defoliate liguan when sang+chatter. Both ♂'s went thru slick+stretch displays while singing. Display not directed exactly toward other bird. After 2-3 minutes two birds exchanged places on branches. A 3rd bird - prob. ♂ or ♀/ - worked over to tree + all flew off. Unable to see if chase. 0615- 1st bird back to "territory" & singing from top of 10 foot tree. Flew to west when gave chatter call. Moved to another location. Have three pairs spaced along cut for electric lines. At about 20-25 yards + 10-15 yards. Each pair in tree or shrub & only one pair not exposed. All were chattering. Pair 3 flew across cut when another bird(s) started chattering over there. Pairs 1 & 2 kept chattering - seemingly in response to chatter of each other (pairs). Saw both members of each of these pairs chattering together. 1 held wings out a little from body + slightly shake. Bill held open + slightly elevated. Pair 1 had one bird sitting on top branch & exposed to view, other bird slightly below, hidden from my angle of observation. Pair #2 had both on branches
