March 5, 2017 – Hutton’s Vireo (Vireo huttoni)
Found along the west coast of North America, in parts of the southwestern United States, and in much of Mexico, these vireos look very similar to Ruby-crowned Kinglets. They eat insects and spiders, along with some small fruits and berries, picking their prey from foliage while hopping between twigs or hovering for a short time. Pairs build the cup-shaped nests from lichen, spiderweb, plant down, bark fibers, fine grass, small leaves, spider egg cases, and moss. Both parents incubate the eggs and feed the chicks. Because their range is split into multiple unconnected areas, there are as many as 12 subspecies with slight size and plumage differences.
