The Fish and Wildlife Service is the leading federal agency for managing and conserving migratory birds in the United States. The Office of Migratory Bird Management is the branch that carries out the Service's responsibilities, which it does in concert with a host of participating partners, both domestic and foreign. The goals of the MBMO are to conserve migratory bird populations and their habitats in sufficient quantities to prevent them from being considered as threatened or endangered, and to ensure the citizens of the United States continued opportunities to enjoy both consumptive and nonconsumptive uses of migratory birds and their habitats.
This U.S. Geological Survey site has North American Bird Breeding Surveys, Bird Banding information and monitoring and Migration information. This site also has a Bird ID that has pictures, range maps, ID tips and life history information for the birds you would like to know more about.
The U.S. Fish and Wildlife site has sections about migratory birds and the Federal Duck Stamp. Of special interest is the Birder page, with links such as Birding Tools, Web Cams, eBird Tracker, and Festivals and Events
Texas State Parks are some of the best places to bird, since Texas has over 600 species to be found in its borders. Most of the individual park sites have bird checklists, habitat information, festival information, and general information about bird trails and specialty birds at their park. Some local parks include Palo Duro Canyon and Caprock Canyon State Parks. Other good birding parks are Davis Mountains State Park and Hueco Tanks State Park.
The Texas Panhandle Bird Club is the local birding club for this area. This site includes tips on where to bird in the Panhandle, spring and fall migrating bird arrival dates, and Christmas Bird Count listings.
Texas Ornithological Society promotes the discovery and dissemination of knowledge of birds; encourages the observation, study and conservation of birds in Texas; encourages formation of local birding clubs; and stimulates cooperation among professional ornithologists.
Cornell Laboratory of Ornithology has a lot of information about our feathered friends. They have several watches, such as Feederwatch and NestWatch, disease ecology, homestudy courses, an Online Bird Guide, and, best of all, the Library of Natural Sounds, the largest natural sound library.
The National Audubon Society specializes in the conservation and education about wildlife. They promote local chapters (such as Lubbock, El Paso, and Norman) all over the United States and have several WatchLists of birds.
