Dull Jay.

Trying to be both blue and green so perhaps.. a mockingjay..

It is a grue jay only if it will devour you in the dark.

It seems we have failed to properly educate our children.

It is ignorance like this this makes me believe that civilization is doomed.

But we only have ourselves to blame

I'm disappointed this wasn't a Nelson Goodman reference.

I wish black cap and Carolina chickadees would do this to further increase the confusion around them.

A gray jay sounds about right.

I get that the changing weather might change their habitual latitudes but there was and is always some "boundary" between the two, no? So there was always a boundary but it moves north or south depending on warming or cooling climates (these birds have been around for millions of years). How did they only mate now?

It will be interesting to learn if the hybrids are fertile or not

Bleen Jay. It's more blue than green, and and also forms a mildly amusing pun, which is good for marketing.
