Very similar and closely related to European Pied Flycatcher. Males have mixed features of Collared and European Pied Flycatchers, but note very large white wing patch and big white forehead. Also note the absence of a white collar and pale rump patch on Atlas Flycatcher. Females are very difficult to distinguish, but note gray upperparts with paler rump and big white primary base patch. Song is a cheery up-and-down series, quite similar to that of European Pied. Calls subtly different from European Pied Flycatcher with a slightly more metallic "whit" and a slower tempo. Inhabits a variety of wooded habitats in the Atlas Mountains.
