Scientific name: Carpodacus mexicanus
Now a familiar bird nationwide, the House Finch was once limited to large areas of the western U.S. A dramatic population expansion from birds released in New York led to the increased distribution. Common at bird feeders, House Finches are susceptible to conjunctivitis, a communicable eye disease.
House Finches often nest in close association with humans in locations such as hanging flower pots. Exceptionally messy nests result from young excreting waste onto the nest rim. The oldest known House Finch lived over 11 years in the wild.
