Taxonomy
editThe Mouse-gray flycatcher was originally described by English ornithologist Philip Sclater in 1861 from a specimen sent to him from Pallatanga, Ecuador.[2] Sclater originally placed it in the genus Myiobius,[3] but it was later placed in Myiophobus. Its specific epithet crypterythrus comes from the Greek crypto meaning hidden, and erythrus meaning reddish, a reference to its subtle reddish wing bars that aren't obviously apparent at first glance. Sclater noted its similarity to the Bran-colored flycatcher (then under the name Myiobius naevius) but identified its difference in size and morphology. It was later considered to be a subspecies of the Bran-colored flycatcher by Carl Eduard Hellmayr under the name Myiophobus fasciatus crypterythrus.[4] Some publications used the name Western Banded Flycatcher for the subspecies during the 20th century.[5] Although its distinct appearance was apparent, some believed that it didn't even warrant a subspecies, with Zimmer considering it conspecific with M. f. rufescens due to a confusing female specimen from where the ranges overlap.[5] In 2023 a proposal to the South American Classification Committee by J.I. Areta and T.S. Schulenberg to split the subspecies M. f. crypterythrus and M. f. rusfescens from the Bran-colored flycatcher was approved unanimously, leading to the split of the Mouse-gray and Rufescent flycatchers as new species.[6]
Description
editThe Mouse-gray flycatcher is a small brownish-grey bird weighing 9.9g. It has a brown back, neck, and crown with a pale belly, throat, and supercilium and greyish-brown breast streaks and cheek. It's wings and tail are a darker brown with the coverts, the sides of the secondaries and tertials, and the tips of the primaries being a rufous color that varies from being a subtle tinge to a very bold ochre. It can be told from the Bran-colored by its darker sepia brown back and paler and more obvious supercilium. The related Rufescent flycatcher is easily differentiated by its rufous unstreaked belly and breast.
Distribution
editIt has a rather restricted range compared to its relatives, being found from extreme southwestern Colombia, Ecuador west of the Andes into Peru reaching its southern terminus in La Libertad Department.
