Martin- I'm leaving you these tapes; they're reported at 15"/sec., so on your tape records you'll only be able to hear them at 1/2 speed (which is useful to study the structure of a call) until you can get the machine adapted to 15"/sec (which I think you need for high frequencies). They can also, of course, be used to audiospectrographs. (1) Tanagridae: a red and black Euphonia recorded in second growth near Guayaquil, Ecuador, 31 January, 1962. (2) Tanagridae: a similarly patterned yellow and dark blue Euphonia "chattering", recorded at the same time and place. (So far as I know, this one does not have the harsh call of the other, but a clear "song" of 4 or more notes, whistled. (pattern sketched at bottom of pg.) (3) Thraupis palmarum - Panama, Rio Piedras, last field before ford 20, Feb. 1962, call of one bird flying overhead. (4) Thraupis episcopus. Panama, mouth of Rio Piedras, 22 Feb., 1962 - presunrise "singing" at 0620. (5) Saltator maximus. Panama, Rio Piedras; 24 Feb., 1962 - fight and chases in bushes, 3 or possibly 4 birds. (6) Ramphocelus icteronotus: Panama, Rio Piedras (near mouth); 23 Feb., 1962. Calls of a male perched in a Poroporo shrub (Cochlospermum) at 0625. (7) Saltator maximus - one of the birds from selection (5) calling at 0700, some time before the recording of selection (5). (8) ? Canal Zone, B.C.I. Dawn song from edge of Clearing, top of a tall tree on W side near new Lab: we couldn't see the bird in 5 min of performance, then it flew farther into forest, sang from another tree briefly and disappeared. In flight a saltator-sized bird. 8 March 1962. (9) ? Panama, Rio Piedras, 2nd growth before gate to first pasture; 4 March, 1962 - unknown predawn song at 0601, possibly a Blue-black Grosbeak. (10)Pitylus grossus (Slate-colored Grosbeak): C.Z., B.C.I.; 10 March, 1962. Calling about 0800 from top of crown of a forest tree near the Clearing. (11)Saltator atriceps: Panama, Rio Piedras beyond the ford; 14 March, 1962. Calling in a large fig about 0620. (12)Tacypnonus rufous: Panama, Rio Piedras, brushy hillside near start; 18 March. Predawn calling of male perched conspicuously on top of a bush; calling with crown ruffled (when seen subsequently). (13)Chlorospingus ophthalmicus, Panama, Cerro Punta; 30 March, 1962. 0700.
