The Greater Pewee (Contopus pertinax) is a passerine and is in the tyrant-flycatcher group. This species range is further north than the other Mexican species. This bird was formerly known as Coues' Flycatcher.
This species is slightly longer than the Olive-sided Flycatcher. The adult Greater Pewee is the largest breeding Contopus flycatcher to breed in the U.S. It is a dull gray-brown bird all over with some birds that have a buff wash on the breast. They have indistinct wingbars and a very distinct crest. The lower mandible is bright orange and is an easy way to distinguish from the Olive-sided Flycatcher in eastern Arizona and west central New Mexico. They are 8" (20.3 cm) long. They have a 13" (33 cm) wingspan and weigh 1 oz. (28g).
These birds love to stay high in trees scanning for insects. They sally and hawk insects from their high perches. The Greater Pewee defends its nesting grounds aggressively. They will attack hawks, jays and squirrels. Their diet consists of insects and maybe berries in cooler months. Their song is a whistled five syllables: "deelip deeree! ah" or famously known as "jose maria". Opening "deelip" is repeated several times before the rest of the song. Also gives "pip" calls like the Olive-sided Flycatcher.
Prefers montane pine forests with an oak understory. Also found in montane deciduous especially sycamore[disambiguation needed] forests and mixed montane oak-pine forest. Found easier in elevations over 6,500' in Arizona and New Mexico. Rare in western Texas.
The Greater Pewee is found year round in central and southern Mexico south through Costa Rica and Nicaragua. It breeds from central Mexico north to southeast and central Arizona and southwest New Mexico. Rarely does it reach southern California, southern Nevada or western Texas.
The female builds the nest high in a horizontal fork of a conifer. The nest is compact and attached by cobwebs. It is made of grass and weeds and is decorated with lichen. The nest is usually lined with fine grasses. She lays 3-4 creamy white eggs sparsely marked with or wreathed with browns and olive. The eggs are 0.8" (21 mm.)
