Hardwickson 1950 Sporophila minuta Oct. 28 5 km. N. Villavicija, 1400 ft., Huila, Colombia, S.A. Commonly seen along railroad tracks and more arid scrub. Also frequently seen near the water in the quebrada. Oct. 30 Singing males noted on high plate W of camp and near R.R. tracks in vicinity of camp. I would class this species as abundant Nov. 1 Many seen during walks to and from Villavicija along the R.R. tracks. Males were singing a great deal. I was impressed by the sight of these little birds landing on a vertical stem of tall grass (2'-3½'), coming in fast and apparently calculating the way the grass would bend. They did not shift their grip on the glass as they "rode" it down through a long arc, and were properly oriented when equilibrium had been reached between the grass stem & gravity. Nov. 8 Villavicija, 1400 ft., Huila, Colombia, S.A. saw many in region of tall (3'-5') grass and trees on island next to town.
