Pine Siskin Dead Bird Update

Pine siskin, a small bird, perched on a branch

In early February, the Wildlife Investigations lab within California Department of Fish and Wildlife (CDFW) confirmed the suspected Salmonella outbreak among pine siskins. CDFW received more than 1,200 dead bird reports within the month of January alone. The Bay Area is a hotspot for the bacteria simply because there is a high concentration of birdfeeders. The District began to receive reports of dead pine siskins and finches in late December 2020. Since that initial report, about half of the total dead birds tested by the San Mateo District Laboratory have been pine siskins (23/42). District staff continues to encourage residents to suspend the use of bird feeders in their yard at this time.
