Description of the Bird

Bird observed if full light, light shade, darker shade: a nice variety of conditions.

Largish Empid with relatively large tail and flattish head. Upper parts quite green in bright light. Belly washed lightly in clear yellow, chest modestly vested with olive wash. Throat white contrasting sharply with auriculars. Quite narrow but white, unbroken and round eyering. Bright white wingbars and edges to blackish retrials despite worn plumage. Primary extension moderately long past terials. Came in swiftly to recording of singing ALFL, but then sat there quietly in front of us for several minutes. As is often the case with Empids, the eyering appears more prominent in photos than in life

Similar Species Discussion

Eastern Willow: flatter head shape (consistent, during prolonged viewing), paler overall color, and lacking gray wash onto back of neck, crown (this bird was green throughout) points to Alder over eastern Willow. The contrast between the green crown and grayer auriculars of the Yuma County bird is typical of ALFL, not of western WIFL
