Golden-winged Warbler Vermivora chrysoptera
Flight call description A rising "szeet" with a sibilant buzz. Also may give a purer-toned "szee".
Fig.1. Texas May 4, 2001 (WRE).
Perched bird.
Examples Diurnal
Similar species Yellow-rumped Warbler is lower and usually less buzzy. See Blue-winged and Black-and-white Warblers, Ovenbird, and short rising seeps.
Behavior Primarily a nocturnal migrant but engages in redetermined migration. Gives flight call regularly while perched and in flight during the day and presumably during nocturnal migration.
"Lawrence's Warbler" Flight calls of a male of this Golden-winged x Blue-winged Warbler hybrid were recorded in New Jersey (see "Lawrence's Warbler" diurnal flight calls).
Spectrographic description Measured calls (N=2) were 57.5 (51-64) mS in duration and in the 6.7-7.9 (6.7-7.8) kHz frequency range (not measuring steep rise at beginning of call or sharp descent at end). The frequency track was single-banded and rising. Eight calls recorded from one individual while it was foraging showed variable modulation characteristics. Some consistently had a modulation spacing of 3.7 mS with around a 250 kHz depth; others had around a 7 mS modulation spacing and a depth of around 920 kHz. A few calls began with the smaller modulation type then switched to the larger (e.g., Fig.2). An individual recorded in New Jersey had a consistently smaller modulation spacing of 3.8 mS and depth of around 250 mS. A Lawrence's Warbler recorded in New Jersey gave calls with a large modulation spacing of 8.7 mS with a 1.2 kHz depth.
