Comprehensive Description

provided by Smithsonian Contributions to Zoology
Vireo huttoni Cassin

To the 8 earlier records of this vireo as a victim of the brown-headed cowbird (Friedmann, 1963:83) may be added 5 more: 3 from California (San Luis Obispo, Ventura, and Santa Barbara counties) in the Santa Barbara Museum of Natural History and the Western Foundation; 1 from near Victoria, British Columbia (Crowell and Nehls, 1973:911); and 1 from Oregon, reported by Anderson (1970:420). In the 1963 summary of available information, 2 records were considered as involving the host race V. huttoni stephensi, 1 from New Mexico, and 1 from Brewster County, Texas. The former is correctly allocated to V. h. stephensi, but the latter can only refer to V. huttoni carolinae, a subspecies not hitherto reported among the victims of the parasite. The record from Victoria, Vancouver Island, refers to the host race V. huttoni insular is, which is the first one reported for that form.

Hutton's vireo

provided by wikipedia EN

Hutton's vireo (Vireo huttoni) is a small songbird. It is approximately 5 inches (12–13 cm) in length, dull olive-gray above and below. It has a faint white eye ring and faint white wing bars. It closely resembles a ruby-crowned kinglet, but has a thicker bill, blue-gray legs, and is slightly larger in size. Its most common song is a repeated chu-wee, or a chew, but will have other variations. Its call is a mewing chatter.

It is found from southern British Columbia in Canada to central Guatemala in Central America. Recent DNA studies suggest this species may be split into at least 2 different species, with coastal Pacific birds showing enough genetic variation when compared to interior ones.

This vireo makes a hanging cup nest suspended from a fork of a tree. The female lays 3–4 eggs. The eggs are mostly white in color, with scattered brown spotting. It prefers deciduous-mixed forests, and is particularly fond of live oak. It feeds by gleaning insects as it deliberately moves through the forest canopy.

Birds are mostly resident year-round, but there may be some altitudinal and short distance migration. Hutton's vireo may join a mixed-species flock for the winter.

The bird's name commemorates the US surveyor William Rich Hutton.[2]
