Description of the Bird

Largish Empid with broad tail, flat head, medium length bill (dark maxilla, pinkish mandible without dark tip). Back and crown moderately bright green, extending down onto auriculars which were gray-green, contrasting sharply with white throat. Crisp thin and very narrow white eyering (circular, no elliptical quality). Some dusky on sides of chest. Belly pale yellowish. Wings blackish with bright buff wingbars, yellow-green to yellow-buff secondary edges and whitish tertial edges. Primary extension long. Tail blackish. Intermittently would flip tail vigourously upward. Twice gave "Peek" call typical of this species. Note that all photos (except one in flight) taken in deep shadow and primarily are used to give an idea of shape and contrast in wing.
