Nordickson 1950 Crotaphaga sulcirostris Oct. 30 5 km. N. Villavicencio, 1400 ft., Huila, Colombia, S.A. Shot 2 (for closer inspection) out of a loose flock of about 8-10 on high plate W of camp. Nov. 2 Saw a mixed flock of C. ani and C. sulcirostris about 500 yds N. of Iquebrada Tajas bridge. The flock apparently included 5 C. ani and 4 or 5 C. sulcirostris. Identification was based only on differences in call and in size. 4 flocks of Crotaphaga were seen at other points between Iquebrada Tajas bridge and camp. There were apparently flocks of C. sulcirostris only.
