| Summary: | a similar pattern, with the most differentiation at the acoustic structure, with unique acoustic structures another subspecies. Morphometric acoustic analysis revealed call and the rattle call) as shared by all taxa at all sites. Differences in acoustic structure of both call types were eight sites in Texas. While many call types were existed for only two or three decades, morphometric analysis greatest between species. Subspecies showed less distinct I recorded vocalizations of allopatric populations of Western identified two structurally distinct call types (the flight inconsistent in structure and tended to intergrade, I morphometric acoustic separation from the other populations occasionally being shared with the nearest population of of both call types showed marked vocal differentiation from of Scrub-Jays at the subspecific level, while the other call other Texas Scrub-Jays. Analysis of one call type suggested populational differentiation. Of particular interest was a Scrub-Jays (Aphelocoma californica texana and A. c. small, isolated population of A. californica found in the specific level, followed by subspecific and, lastly, by Texas panhandle. Although breeding populations may have type suggested separation at the specific level. woodhouseii) and Mexican Jays (A. ultramarine couchii) at |
