The "Bullock's Oriole" has a long wing and relatively short tail. His sharply pointed bill is blue-gray as are the color of his legs. His flight feathers are widely fringed with white. His tail feathers black with an orange base.
The female "Bullock's Oriole" has a gray back and pale belly, and a dull lemon head, breast and tail. Her eye line is dusky. Her wings are blackish with two bold white wing bars and white fringes to her flight feathers. She and her young offspring are often confused with the "Baltimore Oriole".
Even duller than the female Bullock, the juvenile has a pink bill and less well-developed wing bars.
The "Bullock's Oriole" breeds in open woodlands and riparian areas, where cottonwoods provide shade, from British Columbia across southwestern Canada.
Calls or song.
The "Bullock's Oriole" call is a mix of whistles and rattles. The song is more musical: "kip, kit-tick, kit-tick, whew, whee".
Population and distribution.
The "Bullock's Oriole" ranges throughout the western United States. When it gets to the Great Plains, it often hybridizes with the Baltimore. This bird's numbers declined between the '60's and '80's in the far west. They winter in southernmost California and Mexico.
The female nests in a tree or shrub about 10-20 feet up. She constructs a "hanging pouch" of woven plant fibers, which she suspends from a forked branch. This is entered from the top. She lays 4-5 eggs.
