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.

It breeds in South America east of the Andes from Colombia and Venezuela south to Bolivia and Argentina, and on the islands of Trinidad and formerly also Grenada.
It is found at lower levels in humid forest, secondary woodland and forest borders and is often associated with bamboo.
The typical clutch is 2-3 white eggs, which are marked with reddish brown mostly at the larger end, weigh about 1.7 grams each and measure roughly 18 by 13.5 mm. 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 20-25Â°C ambient temperature, the young hatch after 16-18 days, and fledge after about 15 days. They are being fed by both parents, and older nestlings have a voracious appetite. As they near fledging, one can find a parent arriving with new food every few minutes.
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
This species has a large range, with an estimated global extent of occurrence of 10,000,000 kmÂ². The global population size has not been quantified, but it is believed to be large as the species is described as ‘frequent’ in at least parts of its range (Stotz et al. 1996). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
Mainly resident but Northern populations migrate in Austral summer in to South East Peru. No data on routes or boundaries.
