Distribution and Habitat
The Black Phoebe breeds in the west and southwest United States, Mexico and Central America, and parts of South America. In Oregon it is found in river valleys on the Pacific coast, and in California on the western side of Coast Ranges. It breeds throughout the Colorado River valley, and occasionally is found to the north in southern Nevada and southwestern Utah, as well as Arizona and central New Mexico. In Central America it breeds on Baja California, except for the central part of the peninsula, and on interior mainland Mexico southwest to Panama, excluding El Salvador. In South America it is found in the coastal mountains of Venezuela, through Colombia, Ecuador, and Peru, to western Bolivia and northwestern Argentina.
It lives year-round in most of its range and is more sedentary than either of the other phoebes in its genus (Eastern or Say's), although northern populations may be partially migratory. It is always found near water, and is often found at coastal cliffs, river/lake banks, or even park fountains. Habitats must also include a supply of mud for nest building, and the birds' specialized nesting requirements probably cause their somewhat irregular range.

Famous quotes containing the words distribution and/or habitat:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (18561950)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (18421910)
