We share the sponsorship with Orleans Audubon Society. In the Month of January there were calls from California, Colorado, California, Illinois, New Jersey, Tennessee, Texas and Washington. Louisiana birders are calling from all over the state, too. Sponsored by the National Audubon Society and the Cornell Laboratory of Ornithology, BirdSource sponsors many Citizens and Science data gathering projects including Irruptive Bird Survey, Autumn Hawk Watch, Winter Finch Survey, Broad-winged Hawk Survey, Christmas Bird Count, Project FeederWatch, Great Backyard Bird Count, and Classroom FeederWatch. Most species spend the majority of the year in transit or wintering from the southern-most U.S. to South America.
Birds return to their northerly breeding grounds just long enough to breed and raise young.
Therefore, to better understand these birds, we need to map not only their summer distribution but their wintering and migration patterns as well. We know that Tennessee Warblers, for example, move up through the Mississippi and Ohio river valleys in the spring, while in the fall, they typically travel farther east. Blackpoll Warblers likewise take a more easterly path in the fall, with a large portion of these migrants heading out over the Atlantic Ocean north of Cape Hatteras, N.C., and continuing their migration as far south as the Peruvian Andes. Warbler Watch will map the migratory routes of all North American warbler species.
