In 1852, the house sparrow (Passer domesticus) was introduced into the eastern USA from England. Fifty years later it had already developed geographical variation in size and colour. Today it is smallest along the central Californian coast and southeast Mexico, and is largest on the Mexican Plateau, the Rocky Mountains, and the northern Great Plains. The clines in house sparrows that have evolved in North America resemble the clines found in Europe ( Johnston and Selander 1971). The American robin (Turdus migratorius) displays similar geographical variation in size and shape to the house sparrow (Aldrich and James 1991): it is small in the southeastern USA and along the central Californian coast, and large in the Rocky Mountains and associated high plains.
