NOTES: Neotropical Institute Cut # 5. Bulk reel: 77 a) 31/VIII/65. 5:55 to 6:10 AM. Slightly foggy. 5:55 to 6:00 AM. During the period July-August large groups of these birds foraged at dawn (and dusk) around the R.G. building and the Portachuelo. At times they were there daily but then would skip several days. In these flocks it was possible to distinguish two, and sometimes it seemed three, sizes of birds: one small and one large and one that seemed intermediate. Two birds were caught in a net 3/VIII/65 and one was semitorquatus (I donÕt think schaeferi is a valid race) and the other nattereri), a race that is supposedly migratory from the south. Most of the sounds heard resulted when two birds came close together, sometimes in little chases, but whether they indicate conflict or "play" I couldnÕt tell. These flocks havenÕt been noticed since the first week in September. During June I was absent (but during that period one such flock was seen in Guayana and one bird of each of the same two races was collected). In the period before June the birds were also heard occasionally over the R.G. building but didnÕt observe them as was busy on other things. At other places in the R.G. park I did see flocks (see Cuts 4/7, esp. 4). Again they were not consistent in appearing at the same placed on successive days. On those occasions too, I was too busy with other things to pay close enough attention to determine if there were both large and small birds present but by vague memory believe they were of ~ one size. 2/XI/65 PAS Note: A note made in field 5:20 AM, 10/V/66, at Rio Grande, km 12, (El Palmar, Bolivar) says that I had just heard L. semitorquatus giving a song similar to that we hear at Rancho Grande. (See Cut #10 for recordings.) Quality: 2. Level: +3. No parabola. b) 1/IX/65. 5:55 to 6:00 AM. Slightly foggy. [No notes made by recordist.] Quality: 1-2. Level: +5. 36" parabola.
