Geog. Dist. — Mexico. There is said to be a specimen in " the 

 collection of the Philadelphia Academy of Natural Sciences, labelled 

 Rio Grande, Texas, J. W. Audubon," but there is doubt as to whether 

 the specimen was really taken within the limits of the United States. 

 {Cf. Baird, Birds N. Am. 1858, p. 66, foot-note; Ridgw. Man. N. 

 Am. B. 1887, 269.) Its occurrence in Texas is not improbable but 

 the evidence is unsatisfactory.
