观察细节
Long predicted by some as a potential vagrant from Mexico to the United States, the Gray-collared Becard is now recorded for both Arizona and the United States from an immature male well documented in South Fork of Cave Creek Canyon, Chiricahua Mts., COS, 5 Jun 2009 (†, ph. JJo; ph. CW; Figure 8; see N. Am. Birds 63:672). Johnston et al. (2010) argued persuasively that the bird was of the subspecies uropygialis, resident in western Mexico. This individual’s plumage was heavily worn, yet the committee believed it unlikely that it was an escaped cage bird. Reports after 5 Jun were not substantiated.
