Concerns
In the states of Alaska and Washington, and in parts of western Canada, Black-capped Chickadees are among a number of bird species affected by an unknown agent that is causing beak deformities which may cause stress for affected species by inhibiting feeding ability, mating, and grooming. Black-capped Chickadees were the first affected bird species, with reports of the deformity beginning in Alaska in the late 1990s, but more recently the deformity has been observed in close to 30 bird species in the affected areas.

Famous quotes containing the word concerns:
“Art and science coincide insofar as both aim to improve the lives of men and women. The latter normally concerns itself with profit, the former with pleasure. In the coming age, art will fashion our entertainment out of new means of productivity in ways that will simultaneously enhance our profit and maximize our pleasure.”
—Bertolt Brecht (1898–1956)
“In what concerns you much, do not think that you have companions: know that you are alone in the world.”
—Henry David Thoreau (1817–1862)
“Our ideal ... must be a language as clear as glass—the person looking out of the window knows there is glass there, but he is not concerned with it; what concerns him is what comes through from the other side.”
—Elizabeth Bowen (1899–1973)
