CHARLESTON, S.C. (June 15, 2021) - It s not every day that someone discovers a new-to-science bird migration spectacle. It s even more unexpected that such an encounter - in this case, tens of thousands of shorebirds gathering during their annual journey north - would be just a stone s throw from a metropolitan area. But two years ago, that s exactly what happened in coastal South Carolina.
In May 2019, South Carolina Department of Natural Resources (SCDNR) biologist Felicia Sanders and a team of researchers confirmed that approximately 20,000 whimbrel were roosting at night on a small island during their spring migration.

The estimate does not include the much smaller eagle population in the Southwest, especially Arizona. The Arizona population of bald eagles remains on the endangered species list as a subpopulation, due to the limited number of breeding pairs.
However, the Arizona population has also grown steadily in the past 40 years and now includes 90 breeding pairs. That compares to just 11 pairs in 1978. ....
