Stelgidopteryx ruficollis Oct. Nov.2 5km. N Villavicencio, 1400ft., Kaula, Colombia, S.A. None seen all day. It has occurred To us that the flight of those seen in past days has seemed directional in several cases. To the best of my memory the directional flight I have observed has been S (up the valley). Dr. Stebbins has seen northward movement as well. Nov.3 Walked to road crossing at Quebrada 5 of camp at about 7:00 A.M. At this hour and place many swallows had been noted previously, flying over the quebrada. None seen today. Later, followed this quebrada (Quebrada Corbetana) to Magdalena River (all 7 birds thus far collected were collected along this quebrada). Hunted for swallows all the way, and for a short distance down the river. Saw none, either perched or "favorite" (past) roosts or flying. They seem to have all left the area. None have been seen for several days. Nov.5 Saw none, despite almost continuous search, during walk to and from Villavicencio R.R. tracks.
