622b. CALIFORNIA SHRIKE. _Lanius ludovicianus gambeli._

Range.--Pacific coast north to British Columbia.

Similar to the eastern form but with the breast washed with brownish and
with indistinct wavy bars. The eggs cannot be distinguished from those
of the others.

622c. ISLAND SHRIKE. _Lanius ludovicianus anthonyi._

Range.--Santa Barbara Islands, California. Like the last but smaller and
darker. Eggs not distinguishable.

VIREOS. Family VIREONDIDAE

623. BLACK-WHISKERED VIREO. _Vireosylva calidris barbatula._

Range.--A Central American species, breeding in Cuba, Bahamas and
southern Florida.

Like the Red-eyed Vireo but with a dusky streak on either side of the
chin. They build pensile nests of strips of bark and fibres, swung from
the forks of branches. The eggs cannot be distinguished from those of
the next species, being white, more or less specked about the large end
with reddish brown and umber. Size .78 x .55.

624. RED-EYED VIREO. _Vireosylva olivacea_.

Range.--United States, east of the Rockies, breeding north to Labrador,
Manitoba and British Columbia.

This is the most common of the Vireos in the greater part of its range
and is a most persistent songster, frequenting groves, open woods or
roadsides. Their eyes are brown, scarcely if any more red than those of
any other species and I have yet to see one with red eyes outside of
mounted museum specimens. They swing their nests from the forks of trees
at any elevation from the ground but usually below ten feet, and I have
found them where the bottom rested on the ground; they are made of
strips of bark, fibre, etc., and often have pieces of string or paper
woven into the sides; they are one of the most beautiful of bird homes
and are woven so strongly that old nests hang to the branches for
several seasons. Their three or four eggs, often accompanied by one of
the Cowbirds, are laid in May or June; they are white, sparingly specked
with blackish brown. Size .85 x .55.

625. YELLOW-GREEN VIREO. _Vireosylva flavoviridis._

Range.--Southern Texas and southward to South America.

Similar to the Red-eye but greener above and more yellowish on the
sides. The nesting habits are the same and the eggs indistinguis
