PHILADELPHIA VIREO – (Vireo philadelphicus)
The Philadelphia Vireo is a small passerine inhabiting deciduous forests and parklands. It measures approximately 13 cm (5 in.) long. Adults have grey-olive upper parts and light yellow under parts. They have a dark grey crown with a light grey stripe above the eye, and a dark one across the eye, which is black. The bill and legs are grey. They don’t have any wingbars.
The name ‘Vireo’ means ‘green’, and ‘Philadelphia’ refers to the location where the first specimen was found and officially identified. In terms of identification, this bird can be confused with the Red-eyed Vireo due to its similar call, and with the Warbling Vireo due to its similar appearance.
The Philadelphia vireo forages in the canopy for insects, but may also eat berries, especially during migration.
Although the Philadelphia vireo breeds on PEI, its presence on the island is rare. Its overall breeding range covers much of the Canadian boreal forests to the Rockies. During migration it can be found in the eastern half of the USA, and it will winter in southern Mexico and Central America.
Conservation: the population of the Philadelphia vireo appears to be stable and is not a cause for concern.
