On March 28th this year, I co-authored and signed a petition for the U.S. Fish and Wildlife Service to list Wilson’s Phalaropes as endangered under the Endangered Species Act. The petition was coordinated and submitted by the Center for Biological Diversity (read their press release here).
This work is a culmination of two decades of waterbird surveys biologists at the San Francisco Bay Bird Observatory have conducted in San Francisco Bay, including five years of focused summer phalarope surveys carried out with the help of our dedicated team of volunteer community scientists. In the 1980s, during days of peak migration San Francisco Bay had around 40,000 Wilson’s Phalaropes foraging on salt ponds here in order to gain enough fat reserves to continue their migration to wintering grounds to South America.
