Maybe on the wild birds' side, but capitalists are turning it into a full on pandemic through factory farming practices while the US government politely asks them to act responsibly.

I'd say yes and no, not necessarily due to changing temperatures but due to huge quantities of bird livestock (in absolute cosmic horror conditions) but I guess loss of habitat and a polluted environment doesn't help much, animal industry is for sure the biggest drive of viral/bacterial diseases. Which is kinda poetically fitting tbh, considering the nightmare modern day factory farming is.

It's mostly an effect of meat consumption.
