1983 20 February (continued) Sura Trail w/ the AC Job Shortcut trail saw a Cebus and Ateles swaying around overhead and near each other. They were knocking leaves and branches down, and precisely below them I found three medium size reptile eggs. Went into town after lunch on the 18th and walked back hoping to see hawks but didn't. On the 19th, ~0800, spotted an Opheltes alenus coiled loosely ~1.8m above ground on a tall plant at W. end of the old Annex - it squirmed, discharged, inflated, gaped, and struck slowly when handled. Floated from Rafael's House to Station stairs in the Rio Puerto Viejo ~1530-1600h. Saw no herps, but a vulture rose from an area of woods where there was a foul smell. At ~2300 John Cooke brought me a beautiful big Pleiocerus euryzonus found crawling across the sidewalk steps near the old AC Job. It thrashed, wrapped tail around my hand and discharged. Then this AM when I had it out for pictures it did more of all that plus struck several times.
