|house finch (haemorhous mexicanu)|
"Originally only a resident of Mexico and the southwestern United States, [house finches] were introduced to eastern North America in the 1940s. The birds were sold illegally in New York City as "Hollywood Finches," a marketing artifice. To avoid prosecution under the Migratory Bird Treaty Act of 1918, vendors and owners released the birds. They have since become naturalized."
