The Greater Pewee is a distinctive flycatcher that occurs in southeastern Arizona, where the species reaches the northern edge of its range. It is most often associated with pine-oak and montane coniferous forests in the “Sky Islands” of Cochise, Santa Cruz, and Pima counties, particularly in mountain ranges such as the Chiricahuas, Huachucas, Santa Ritas, and Catalinas. In Arizona, Contopus pertinax breeds primarily between 5,000 and 8,000 feet in elevation, favoring tall pines and sycamores where it sings from prominent perches.

This species is larger than other North American Contopus flycatchers, averaging about 8 inches in length, and is notable for its long, crested appearance and plain gray-brown plumage, lacking the obvious wing bars of Western Wood-Pewee (Contopus sordidulus). Its loud, whistled song—often rendered as “José María”—is one of the most recognizable bird calls in Arizona’s mountain canyons.

The Greater Pewee (Contopus pertinax) is primarily an insectivore, sallying out from high perches to catch flying insects, though it may also consume berries and other small fruits seasonally. In Arizona, it is a summer resident, arriving in late April or May and departing by September, with rare overwintering individuals documented. Its breeding range in the state is limited, but where found, the species can be locally common.
