34. Dendrœca æstiva (Gmel.) Baird. Yellow Warbler.
210, ♂ ad., Cienega Station, April 16. Length, 5; extent, 7.50; wing, 2.75; tail, 2.20; tarsus, .74. “Iris dark brown; bill dark horn color above, lighter below; legs pale brown. Common in the migrations.”
35. Dendrœca coronata (Linn.) Gray. Yellow-rumped Warbler.—Chiricahua Mountains; a single specimen, taken March 26.
From its general dispersion over North America, the Yellow-rumped Warbler was of course to be expected in Arizona, at least as a visitor, but I cannot learn that it has been previously detected within the limits of that Territory. Mr. Stephens, however, sends me an adult female which must be referred to coronata, although it is in some respects peculiar, if not intermediate between that species and auduboni. The wing-bands are as distinctly separated as in coronata (with females and immature males of both species this character is not always well-defined), and the throat, generally, is equally white, but on its left side, adjoining the maxillary line, there is a small patch of the faintest possible yellow. The light superciliary stripes, which should be at least indicated in female coronata, are also entirely wanting.
114, ♀ ad., Chiricahua Mountains, March 26. Length, 5.50; extent, 8.70; wing, 2.98; tail, 2.52. “Iris brown.”
36. Dendrœca auduboni (Towns.) Baird. Audubon’s Warbler.
