Description
Adults have a long tail, brown above and black-and-white below, and a black curved bill with yellow especially on the lower mandible. The head and upper parts are brown and the underparts are white. There is a yellow ring around the eye. It shows cinnamon on the wings in flight. Juveniles are similar, but the black on the undertail is replaced by gray.
This bird has a number of calls; the most common is a rapid ka ka ka ka ka kow kow kow.
There is an ongoing debate regarding the taxonomic status of the western race and if it is distinct from those birds in the east. This question is significant to the conservation status of this species in the west, where it has declined to a tiny fraction of its population a century ago. Populations of this species in western North America are in steep decline. The bird disappeared from British Columbia, Washington, and Oregon during the first half of the twentieth century. Eastern populations have declined as well, though not as precipitously.

Famous quotes containing the word description:
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
