Playas de Santiago, 1 km. NW Mangaillas, Oliva, Oct. 27, 1957. A trail through very heavy deciduous forest, with leasy understory of brush and vines. Returning to road, noted several hundred long-winged swallows or pewee flies, flying over road. The one collected (2293) was moderately fat, presumably a migrant. Noted northern Phalaropes abundantly, in pools & lagoons bordering the road. Several chases of Amazilia nutte noted. Volatinia noted displaying, heard giving "jeet- jeet" note, but the displays are of low intensity, not comparable in frequency of display flights or length of display periods to breeding behavior. Birds noted today, not seen before: Frigate-bird, Green Heron, Black & Turkey Vultures, Buteo ridgwayi, Arorets, Stilt's, Least Tern, Aratinga canicularis, Boat-tailed grackle, Mockingbird. Western Fly- catchers are abundant in woodland, both in dense, shaded forest, & in more open situations. They are active up to late a.m. (11:30) at least, long after most other species are quiet. The aggressive "chrip" note was heard several times, and one fight was noted with both birds giving repeated "chrip" notes. Further, individuals frequently reacted to my presence by giving repeated "kist" note, the typical alarm note series heard during the breeding season. The "chrip" & "kist alarm notes" are thus a part of the year-round vocal repertoire, & should not be con- sidered as restricted to the breeding season only.
