Notwithstanding their enormous range, House Finches, like most birds, are threatened by pesticides. Their fast-paced song bounces up and down, usually ending with a slurred note that helps distinguish them from Cassin's and Purple Finches. Regardless of the region they occupy, male House Finches take to high perches, where they sing with gusto for extended periods. Among North America's most widespread songbirds, these resolute singers are nothing if not adaptable. Since their introduction in New York from the western United States in the 1940s, House Finches have been sharing their exquisite song with an ever-growing human audience, which now includes most of the eastern United States. ABC's Migratory Birds and International programs are working with partners throughout Central and South America to improve land management and create protected bird reserves that support wintering Wood Thrushes, as well as other declining species such as the Golden-winged Warbler. In just the last 50 years, the Wood Thrush population has been reduced by half, due in part to widespread habitat loss. The reason why may lie in the fact that males sometimes sing - and harmonize -by employing pairs of notes simultaneously from both sides of their y-shaped voice boxes.ĭespite the Wood Thrush's large range in the eastern United States, its song is fading. In fact, multiple listens inspire greater appreciation. But familiarity hardly dispels the beauty of the Wood Thrush's song. This tireless singer is one of the first birds to be heard in the morning and one of the last to quit in the evening. Celebrated by poets and renowned as one of nature's greatest singers, the Wood Thrush (and its brethren, including the Swainson's Thrush) occupies a class of its own.
