Euler's flycatcher (Lathrotriccus euleri) is a small
In appearance, it closely resembles the Empidonax flycatchers, and was formerly placed in that genus, but differs in anatomical and molecular characters.[3] Euler's flycatcher is on average 12.7 centimetres (5.0 in) long and weighs 10–11 grams (0.35–0.39 oz). The upperparts are olive-brown with darker brown wings and two dull buff wing bars. The throat breast is grey, the breast is brown, and the abdomen is pale yellow. There is a white eyering, but no supercilium. Sexes are similar. There are other races, differing in the tone of the upperpart or underpart colour. The call is a loud hoarse chee-chi-wi-wi-wi.
This species is found in the lower and middle levels of forests. Euler's flycatchers are inconspicuous birds, tending to keep to undergrowth perches from which they sally forth to catch insects; they are also capable of hovering flight to pick off prey from plants, but use it far less often.[4]
In
The typical clutch is 2–3 white eggs, which are marked with reddish brown mostly at the larger end, weigh about 1.7 grams (0.060 oz) each and measure roughly 18 by 13.5 millimetres (0.71 in × 0.53 in). Only the female incubates, and she will every now and then leave the nest for various reasons. When on the nest, the male provisions her with food. At about 20–25 °C (68–77 °F) ambient temperature, the young hatch after 16–18 days, and
It is often fairly common, and on a global scale it is not considered threatened. However, the Grenadan Euler's flycatcher (L. e. flaviventris) has not been recorded since the early 1950s, and is likely
