Rising whistled "pawee" calls. Best recorded calls are near the end of the clip.
观察细节
Continuing *mega since yesterday morning (9/16) when it was first positively identified by Kahle/Sieburth. Appears to be the 4th MRN county record and 17th CA record. Located easily by its near constant calls and hawking from various perches in the large cypress closest to the residence. Wood-Pewee by size, nondescript grayish above and pale below with whitish wingbars, a hint of dark vest and long pp (versus empidonax flycatchers). While not entirely diagnostic by themselves, a combination of features such as lighter breast (than WEWP); bright, nearly all orange lower mandible with only a dark tip; and calls (dry "plit" and whistled, slightly rising "pawee") supports the identification as EAWP over the very similar WEWP. Calls of both species during migration and winter can be strikingly similar.
