I’ve been keeping track of news articles about covid transmission to non human animals. I have only seen transmission to mammals. Zoo animals, deer, cats, dogs, primates. Not birds. Birds have a higher body temperature which may be part of the reason that some mammal viruses don’t do well in birds and some bird viruses don’t do well in animals.
I have not read of ANY incidences of COVID in birds.
According to everything I've read and heard, birds are not susceptible to COVID. At the local zoo, there were tigers and camels that recovered from COVID. I follow horse racing and know of several race horses that suffered from a different form of COVID than affects humans. But no reports of any kinds of birds being diagnosed with any form of COVID. Neither are parrots susceptible to the common cold.
Thank you for having responded to my post! I ended up testing positive for almost 2 full weeks, and it was comforting to know that I didn't have to isolate from my quaker or risk making him sick. (He didn't get sick, and he loved having me around full-time for 2 solid weeks!)
