We've added a few new Birdorable birds this week, the first one being this Eurasian Tree Sparrow. In eastern Asia this cute little bird is widespread in towns and cities, but in Europe, where the House Sparrow is occupying the cities, it is a bird of wooded areas and open countryside. It is not an endangered bird globally, but it is declining in western Europe due to change in farming practices and use of herbicides. There is also a small population of about 15,000 birds in the United States, around St. Louis and parts of Illinois and Iowa. These birds, believe it or not, are descendants of 12 birds taken over from Germany that were released in 1870 in an attempt to enhance the North American avifauna. The birds were set free in Lafayette Park in St. Louis by a local bird dealer. Other European birds were also released, including Goldfinches and Chaffinches, but only the Eurasian Tree Sparrow successfully established a breeding population. If you're ever in St. Louis and want to find a Eurasian Tree Sparrow you can find some good instructions here.
