Villavicencio, 1600 ft., Meta, Colombia, S.A.
Three small individuals seen (by headlamp)
(8' wide x3' deep in hills)
in pool in creek just S of town. The pool
was a large one for this creek; it was about
18' wide and roughly 36' long (estimated), apparently
more than 3 ft. deep. It [illegible] was surrounded
by cut banks (3' on one side, about 6' on the other
side). The water of the creek was "milky-
clear" and smelled of sewage (?). The creek
was fairly rapid in the shallow hills, but
the water had no perceptible current in
the pool. Drifts of and rafts of what
appeared to be rice hulls, and stream
debbris (sticks, etc.) piles were present.
All three were first seen in and near a
mass of stream debris and ooze (+ rice hull
"raft") near the higher cut bank. Later
one or two were also seen at
intervals near the lower cut banks
opposite, and under overhanging grass
from this bank (always only head visible,
usually detected only by eyeshine).
We were not carrying a gun, and attempts
to snare them proved unsuccessful.
