Since May of this year, several states, including New Jersey and PA in our area, have seen a bird death event that affected young songbirds (chicks and chicks). A recent press release from the New Jersey Division of Fish and Wildlife describes the observed symptoms: "Some (but not all) of the affected birds show neurological symptoms such as head tremors, leg palsy (partial paralysis or weakness), ataxia (fall of the side), or inability to stand up and excessive vocalization. In addition, most birds are in good physical condition and are likely to be still being fed by their parents. "
The species most commonly affected are songbirds, songbirds such as robins, cardinals and blue jays, and starlings. A cause for this event has not yet been found; Authorities in affected jurisdictions are working together to find the cause.
None of the following pathogens were detected in the birds tested: salmonella and chlamydia (bacteria), avian influenza virus, West Nile virus, coronavirus, Newcastle disease virus, herpes virus, smallpox virus and Trichomonas parasites. Toxicological tests for heavy metals and pesticides / herbicides were negative.
Over time, fewer affected birds have been reported in Pennsylvania. In addition, there is no evidence that the cause of bird death affects other animals or humans.
On August 13, the PA Game Commission (PGC) issued a press release repealing the recommendation to stop feeding birds and maintain bird baths. There was no evidence that gathering birds at a feeding station increased their risk of being affected. They also recommend continuing to look out for sick or dead birds and contacting the nearest PGC office.
If you keep a feeding or watering bowl for birds, the PGC recommends cleaning it at least once a week as a prevention against more common illnesses. This Audubon link has cleaning tips and other bird feeding ideas: https://auduboninternational.org/wp-content/uploads/2019/03/WHM-Bird-Feeding.pdf .
