Vendrichon 1950 Tamendua Oct. 26 5 pm. N. Villavegja, 1400 ft., Huila Colombia, S.A. Local name is "oso ormigero". Tonight at about 7:30 P.M. heard call which Paulino said was made by this animal. The call consisted of 1, 2, or 3 notes; if more than one, on descending scale: "who"..."who"..."who" Oct. 29 Out goiblighting with Paulino and Pero; walked road to Duebroda Lajas, followed Duebroda Lajas to R.R., and returned to camp via R.R. tracks. In this circuit, heard what Paulino calls the "oso ormigero" many times in at least 12 widely-separated places. As far as I could tell, the calls seemed to come from higher, drier areas, but this does not conform to Paulino's description of their habitat. Having now heard the call many times, I have decided it sounds like nothing else so much as it sounds like a bored person: "Ho- Ho- Hum"
