A new intrageneric Dendroica hybrid from Hispaniola

Abstract

On 7 November 1993, while Latta (SCL) and Wunderle (JMW) were mist-netting in a shade coffee plantation 2 km northwest of Jumunucu, La Vega Province, Dominican Republic (elevation 600 m), an unusual-appearing warbler was captured when it responded to the playback of American Redstart (Setophaga ruticilla) chip-notes. Because they were unable to identify the individual (which appeared to be a Dendroica), SCL and JMW made extensive notes on plumage characteristics and measurements, and photographed and color-banded the bird. It was seen repeatedly in the following eight days in the same coffee plantation, after which time SCL and JMW left the area. Comparisons of their descriptions with specimens at the University of Michigan Museum of Zoology (UMMZ) failed to provide an identification of the bird. It was still present at the same location when SCL and JMW returned on 22 January 1994, at which time it was collected.
