Overview
Greater Pewee: Large, plump flycatcher, olive-gray upperparts, white throat, gray breast, pale yellow belly. Slender crest. Broad, flat bill is two-toned: upper mandible is dark, lower is orange. Wings and tail are dark. Short flights on rapid shallow wing beats. Sallies out to take insects in air.
Range and Habitat
Greater Pewee: Breeds from central Arizona and southwestern New Mexico southward. Spends winters mainly south of the U.S.-Mexico border. Preferred habitats include highland coniferous forests, especially pine and pine-oak.
Flycatchers (Tyrannidae)
ORDER
The PASSERIFORMES (pronounced pas-ser-i-FOR-meez), a large taxonomic order that includes antbirds, cotingas, and flycatchers, is composed of one hundred eighteen families of birds.
FAMILY TAXONOMY
The Tyrannidae (pronounced tie-RAN-uh-dee), or tyrant flycatchers, is a very large, successful family of four hundred and twenty-four species in one hundred genera only found in the Americas.
NORTH AMERICA
In North America, one hundred forty-seven species of flycatchers in fifty-eight genera have occurred. These include the brilliant Vermillion Flycatcher, the sassy kingbirds, and the bridge-loving phoebes.
KNOWN FOR
Some flycatchers are known for their bold, aggressive behavior, this family often called the Tyrant Flycatchers for this reason. The Eastern Kingbird in particular, seems to go out of its way to chase much larger birds (such as Turkey Vultures) away from its territory.
PHYSICAL
Small to medium in size, flycatchers have stocky heads with medium sized beaks, tails that vary in length, and long wings. They also have short legs suited to their arboreal lifestyles.
COLORATION
Aside from the brilliant red and black plumage of the male Vermillion Flycatcher, most flycatchers are plumaged in dull grays, greens, and browns with whitish or yellowish underparts. A few other exceptions to this color scheme are the frosty plumage of the Scissor-tailed Flycatcher highlighted by salmon pink underwings, the orangish coloration of the Say’s Phoebe, and the black and white plumages of the Eastern Kingbird and Black Phoebe.
GEOGRAPHIC HABITAT
Members of the Tyrannidae occur in most types of forested and non-forest habitats in North America except for the tundra. Some species such as the Willow Flycatcher and Black Phoebe are associated with wetland habitats, others like the Olive-sided and Hammond’s Flycatchers need coniferous forests, and other species such as the Cassin’s Kingbird and Say’s Phoebe, occur in grasslands. Related species often replace each other in different habitats or regions such as in the case of the Eastern and Western Wood-Peewees.
MIGRATION
Most flycatchers are long distance migrants to Central and South America.
HABITS
Flycatchers do not nest in colonies and mostly forage in pairs or alone although the Eastern Kingbird forms flocks during migration and on its wintering grounds in Amazonia. Most North American flycatchers share a similar foraging strategy that often varies by niche and prey item. This foraging strategy involves watching for insects from a perch, sallying out to catch one with a snap of the beak, and returning to the perch to eat it.
CONSERVATION
Most flycatcher species have stable populations in North America. The Olive-sided Flycatcher, though, has sharply declined throughout its range possibly due to habitat destruction on its wintering grounds and has been listed as near-threatened.
INTERESTING FACTS
The Alder and Willow Flycatchers are so similar in plumage that visual identification is nearly impossible. These two species were actually considered to be one species, the “Traill’s Flycatcher,” until small differences in their plumages and distinct differences in their vocalizations showed that they were separate species. This was also the case for the Cordilleran and Pacific-slope Flycatchers, and the Eastern and Western Wood-Peewees.
