"The scientists ruled out some possible causes: bacteria, West Nile virus, an avian influenza and even coronaviruses. Toxicology tests came back negative for pesticides and heavy metals. Some people speculated that cicadas, or substances used to get rid of them, were the culprit."
Quote taken from Washington Post article about the mysterious bird illness from 2021.
" The illness is not caused by any of the major known bird diseases such as West Nile, salmonella, avian influenza, House Finch eye disease, Trichomonas parasites, etc.
The species most frequently affected are fledgling (juvenile) Blue Jays, Common Grackles, European Starlings, and American Robins, along with a few other species. Symptoms include crusty eyes and neurological signs such as tremors or partial paralysis.
We don’t know if the illness is caused by a disease organism (i.e., virus, bacteria, or parasite), or if it’s the result of a toxic substance in the landscape.
If it’s a disease, we don’t know how it’s transmitted. It might be directly transmissible from bird to bird (like a cold or the flu), or might require a vector (such as with malaria, where a mosquito transmits the illness)."
