Hybridization between divergent taxa can provide insight into the breakdown of characters used in mate choice, as well as reproductive compatibility across deep evolutionary timescales. Hybridization can also occur more frequently in declining populations, as there is a smaller pool of conspecific mates from which to choose. Here, we report an unusual combination of factors that has resulted in a rare, three-species hybridization event among two genera of warblers, one of which is experiencing significant population declines. We use bioacoustic, morphometric and genetic data, to demonstrate that an early generation female hybrid between a golden-winged warbler ( Vermivora chrysoptera ) and a blue-winged warbler ( V. cyanoptera ) went on to mate and successfully reproduce with a chestnut-sided warbler ( Setophaga pensylvanica ) . We studied the product of this event—a putative chrysoptera × cyanoptera × pensylvanica hybrid—and show that this male offspring sang songs like S. pensylvanica , but had morphometric traits similar to Vermivora warblers. The hybrid's maternal parent had V. chrysoptera mitochondrial DNA and , with six plumage-associated loci, we predicted the maternal parent's phenotype to show that it was likely an early generation Vermivora hybrid . That this hybridization event occurred within a population of Vermivora warblers in significant decline suggests that females may be making the best of a bad situation, and that wood-warblers in general have remained genetically compatible long after they evolved major phenotypic differences.

Abstract The importance of the black facial pattern in sexual selection in Golden-winged Warblers (Vermivora chrysoptera) was evaluated through experimental plumage modification. We lightened the throat patch and eye mask with hair bleach, which essentially created artificial Brewster's Warbler (F1 generation of Golden-winged Warbler × Blue-winged Warbler [V. pinus]) plumage phenotypes. Experimental males lost their original territories and failed to obtain mates. We concluded that there is sexual selection against the Brewster's facial pattern. Sexual selection attributable to the face pattern may explain the apparent greater effect of hybridization on Golden-winged Warblers than on Blue-winged Warblers.

AbstractThe Golden-winged Warbler (Vermivora chrysoptera) has a simple, stereotyped song consisting of an introductory trill (Z) followed by a variable number of similar lower-pitched trills (B). Individual variation is slight, with overlap in the seven individuals studied in syllables per trill, maximum and minimum frequency (pitch), frequency range, duration and interval. However, differences in frequency and perhaps number of syllables per trill may be sufficient for individual recognition. Species recognition probably depends on the grosser aspects of the same parameters. Playback experiments were conducted with both natural and artificial songs to test the effects of number, kind and ordering of trills. Responses were measured in terms of number of playbacks within 30 feet of the speaker. A rigid ordering is necessary for maximal responsiveness with the Z preceding any B trills. The natural song is "read" from the first Z trill to the last B trill. Responsiveness differed according to the number of B trills. Both the Z and B trills are necessary for maximal responsiveness. The minimum effective song was ZB, a naturally occurring song in conflict situations. The song of this species is particularly rich in possibilities for transmitting motivational information. We suggest that such information transfer occurs through varying the number of B trills, amplitude, rate of singing and major changes in the song (frequency, syllables per trill, interval).
