Day 18 of extinct birds - the Carolina parakeet or Carolina conure
The Carolina parakeet was one of only three species of parrot native to the US. They were very social birds, found in large flocks, and multiple females will lay eggs in a single nest. Interestingly, they were known to eat a lot of cocklebur seeds which are toxic (at least to mammals). Another interesting thing is that the last captive parakeet died in the same cage that the last passenger pigeon died, 4 years after.
