Avocet -American


The American Avocet is a long-legged shorebird. It is characterized by a long, thin bill that curves upward. In the female avocet, the bill curves up a little bit more. This shorebird has a distinctive black and white striped pattern on its back and sides. During the breeding season, the head and neck are a pinkish-tan and during the winter they are a grayish-white color. The avocet also has bluish-gray legs and feet; thus its colloquial name, "blue shanks." American Avocets commonly are found on mudflats, in saline lakes, in fresh water and saltwater marshes and on coastal bays. They may be found in migration from March to May, and again from July to October. Their nesting grounds are in the Great Basin region of the western United States. Locally, they breed in the Panhandle and in West Texas on the shores of inland playas and along the Gulf coast. They winter as far south as Mexico and Guatemala. As a protected species under the Federal Migratory Bird Treaty Act, the only real threat to them is the loss of breeding and wintering grounds due to habitat degradation and destruction.

» Habitat: mudflats, in saline lakes, in fresh water and saltwater marshes and on coastal bays.
