Warbling Vireo
(Vireo gilvus) B |

RANGE: Breeds from southeastern Alaska, northern
British Columbia, and southern Mackenzie southeast to southern
Ontario and southern New Brunswick, south to northern Mexico,
Alabama, and Virginia. Winters mostly in Mexico and Central
America.
STATUS: Common and widespread.
HABITAT: Inhabits open deciduous and mixed deciduous-coniferous
forests, especially streamside vegetation, but also in groves,
scrubby hillside trees, and residential areas. In mixed forests,
generally associated with the deciduous trees, and prefers
forests with a substantial forb or shrub layer and low to
intermediate canopy cover.
SPECIAL HABITAT REQUIREMENTS: Scattered deciduous trees or
wooded streamsides. Strongest nesting habitat
associations in (1) Red alder, (2) Western riverine
woodland, and (3) Streamside wetland and shrubland.
NEST: Builds a cup nest that is usually suspended from a
horizontal branch of a deciduous tree, often poplar or aspen,
generally in branches well away from the tree trunk and higher
than those of other vireos (20 to 90 feet above the ground).
FOOD: Gleans much of its food from the mid to upper canopy of
deciduous trees. Eats mostly animal matter but includes some
small fruits.
