or cleared the infection quickly

One lady telephoned me because she was worried that the Cockatiel that was to stay with her while its owner was on holiday could pass on the virus.This seems to be extremely unlikely. The World Parrot Trust advises that “your bird cannot become infected by this strain of Coronavirus and so you cannot get the virus from your birds.”

DJ, CoViD-19 is widespread in lots of (sea)mammals...https://www.wpr.org/news/fish-study-coronavirus-covid-pathogens or https://www.wpr.org/news/fish-study-coronavirus-covid-pathogens DJ, Some fish (https://pubmed.ncbi.nlm.nih.gov/32159234/ or https://pubmed.ncbi.nlm.nih.gov/32159234/ carp from Wuhan tested positive ???)

As recently as a decade ago, the ability of HPAI H5 viruses to be carried long distances by migratory birds was still being hotly debated, with many experts claiming birds were being falsely accused (see Bird Flu Spread: The Flyway Or The Highway?). 
While some outbreaks were clearly driven by migratory birds, until recently most birds either succumbed to the virus - or cleared the infection quickly - limiting their ability to carry the virus over long distances (see PNAS: The Enigma Of Disappearing HPAI H5 In North American Migratory Waterfowl).
By 2016, the H5N8 virus had overtaken H5N1 as the dominant subtype, and while it was more adept at hitching rides on migratory birds, it showed few signs of becoming a zoonotic threat.  H5N1 waned, as H5N8 continued to spark major epizootics in North America (2015), in Europe (2016-17), and crossed the African equator in 2017. 

DJ, CoViD weakens immunity-give more room to H5 etc.
