Behavior

1. The Greater Pewee is an insectivorous bird, primarily preying on flying insects, which it catches in mid-air using its agile flight and large bill.
2. This bird species is known for its distinctive "perch-and-sally" hunting strategy, in which it perches on a branch, scanning the surrounding area for insects, before swiftly launching into the air to capture its prey and returning to its perch.
3. Greater Pewees are generally solitary birds, only coming together during the breeding season to form monogamous pairs.
4. During the breeding season, male Greater Pewees are known for their persistent, melodious songs, which serve to attract females and establish their territory.
5. When threatened or disturbed, Greater Pewees can become quite aggressive, engaging in various displays, such as wing-flicking and tail-spreading, to deter potential intruders.

Habitat

1. The Greater Pewee's preferred habitat consists of mature forests and woodlands, including both deciduous and evergreen tree species, where it can find an abundance of insects and suitable nesting sites.
2. In addition to forests, the Greater Pewee can also be found in riparian areas, where the presence of water attracts an abundance of insect prey.
3. During migration, the Greater Pewee can be observed in a wider range of habitats, including suburban parks and gardens, as it makes its way to its wintering grounds in Central America.
4. The Greater Pewee typically nests in the mid to upper canopy of trees, constructing a small, shallow, cup-shaped nest made from plant materials such as twigs, grasses, and moss.
5. The species' ability to adapt to various habitats has allowed it to maintain stable populations throughout its range, despite ongoing habitat fragmentation and other environmental challenges.

Facts

1. The scientific name of the Greater Pewee is Contopus pertinax, belonging to the family Tyrannidae, which includes over 400 species of flycatchers.
2. Despite its name, the Greater Pewee is not closely related to the Eastern Wood-Pewee or the Western Wood-Pewee, which belong to a different genus within the same family.
3. The Greater Pewee's song is a distinctive series of clear, whistled notes, often described as sounding like "Jose Maria" or "piz-WEER."
4. Although the Greater Pewee is primarily insectivorous, it has been known to occasionally consume small fruits and berries, particularly during migration.
5. The Greater Pewee has a relatively long breeding season, with nesting activities observed from late April to early September, depending on the location within its range.
