The much more colorful Carolina parakeet was native to Illinois and did just fine there for thousands of years, until it was exterminated.
Curious about your mention of the Carolina parakeet, I found interesting tidbits on wiki:
“Carolina parakeets were probably poisonous—American naturalist and painter John J. Audubon noted that cats apparently died from eating them, and they are known to have eaten the toxic seeds of cockleburs.”
“...It was especially noted for its predilection for cockleburs (Xanthium strumarium), a plant which contains a toxic glucoside, and it was considered to be an agricultural pest of grain crops.”
