Contopus cooperi

Identification

18-20 cm (7.1-7.9 in)
The contrasting (off-)white centre line and dark breast sides are diagnostic.

Large-billed
Heavy-headed
Breast and flanks deep olive-brown/dark grey
Throat and central breast strongly contrasting (off-)white.
Base of tail with white feather tufts
Tail broad, notched

Similar Species

Eastern Wood-Pewee and Western Wood-Pewee similar but with longer tails and shorter bills, and they lack blurry breast streaks. Greater Pewee similar but without the vested appearance. Other pewee species such as Dark Pewee and Northern Tropical Pewee are broadly similar, as are empids. All these species lack the strongly contrasting whitish centerline with darker sides ("vest" or "waist coat")

Distribution

Breeds temperate North America; (Alaska, Canada through to the United States); winters south to Bolivia.

Taxonomy

This is a monotypic species^[1].

Formerly Contopus borealis.
Formerly in the genus Nuttallornis.

Habitat

Boreal forest, and forest edges open wooded areas, riparian sycamore and oak woods, farm fields,

On migration may be seen in rain forest at heights of around 600 m.

Behaviour

They are inclined to perch on the very tops of trees.

Breeding

The nest is formed from twigs and lined with soft materials, such as lichen, moss and grass. It is placed high up in an evergreen tree, near the end of a branch. The clutch consists of 3 brown-spotted buff eggs.

Diet

Diet includes winged insects.

Vocalisation

Song is a loud whistled "What PEEVES you?" with the middle note highest and strongly accented. Common call is a "pip-pip-pip" similar to call of Greater Pewee.

Movements

Long-distance migrant, wintering in Central and South America; longest migration route of any North American flycatcher.

-1/2" (19 cm). A large-billed and heavy-headed bird, deep olive-brown, with dark sides of breast and flanks separated by white patch down center of breast. White feather tufts protrude from lower back at base of tail; tail broad and prominently notched. Compare with Greater Pewee.

 ==Habitat==
-Boreal spruce and fir forests, usually near openings, burns, ponds, and bogs.
+Boreal forest, and forest edges open wooded areas, riparian sycamore and oak woods, farm fields,
+On migration may be seen in rain forest at heights of around 600 m.
 ==Behaviour==
-brown-spotted buff eggs in a twig nest lined with lichens, mosses, and grasses, placed near the end of a branch among the foliage well up in an evergreen tree.
+They are inclined to perch on the very tops of trees.
-Song a distinctive and emphatic quick-three-beers; call a loud pip-pip-pip.
+====Breeding====
-This flycatcher almost always perches on dead branches in an exposed position at or very near the tops of the tallest trees. Analysis of stomach contents of these birds has shown that everything it eats is winged; it takes no caterpillars, spiders, or other larvae.
+The nest is formed from twigs and lined with soft materials, such as lichen, moss and grass. It is placed high up in an evergreen tree, near the end of a branch. The clutch consists of 3 brown-spotted buff eggs.
