Euler's Flycatcher

Euler's flycatcher is 12.7 to 13.5 cm (5.0 to 5.3 in) long and weighs 9 to 13.8 g (0.32 to 0.49 oz). The sexes have the same plumage. Adults of the nominate subspecies L. e. euleri have a warm olive-brown crown, nape, and cheeks. They have a whitish eye-ring and a faint pale stripe above the lores. Their upperparts are mostly olive-brown with a brown rump. Their wings are dusky with pale buff ends on the coverts that show as two wing bars. Their secondaries and tertials have pale buffy-brown edges. Their tail is dusky. Voice: In Brazil Euler's flycatcher sings a "varied series of 2-5 notes, 1st one normally stressed and slightly longer than slightly descending notes; thereafter Tjeew-tjuh or Tjeew-terduh". In Venezuela its song is described as "an abrupt, almost explosive FEEU! pe'pe 'pe'p'p, 1st note loudest, last notes run together, buzzy and downscale".
