Sulphur-rumped Flycatcher Myiobius sulphureipygius Scientific name definitions

Sulphur-rumped Flycatcher is a small flycatcher that occurs from southern Mexico south to western Colombia and Ecuador. It generally is dull olive above, with a contrasting sulphur yellow rump, dusky wings, and black tail. The breast is tawny, and the belly is pale yellow. Males also have a yellow patch, usually concealed, on the center of the crown. Sulphur-rumped Flycatcher exhibits the very active foraging style typical of Myiobius: individuals often hop energetically from branch to branch and aerially pursue flying insects. Sulphur-rumped Flycatchers rarely are seen together, but singles frequently associate with mixed-species flocks. During breeding, the females create extravagant hanging, pear-shaped nests. According to the IUCN Red List, Sulphur-rumped Flycatcher is a species of Least Concern, because it is widely distributed and fairly common.
