Vireos (Family Vireonidae)
The vireos are a group of small to medium-sized, mostly passerine
birds restricted to the New World.
They are typically dull-plumaged and greenish in color, the smaller
species resembling wood warblers apart from their heavier bills.
They range in size from the choco vireo, dwarf vireo and lesser
greenlet, all at around 10 centimeters and 8 grams, to the pepper-
shrikes and shrike-vireos at up to 17 centimeters and 40 grams.
