Beyond the implications for birds, does this have implications for estimating the "walnut sized" brains of some of the herbivore dinosaurs not to mention the larger brained carnivore ancestors and cousins of the birds?

I'm not surprised about the new estimate of bird intelligence. I think anyone who has watched birds will agree they are smart.

I don’t care what anyone says...crows are among the smartest non-human animals on the planet!

Some birds will ‘fowl’ their own nests!

Ounce for ounce birds have significantly more neurons in their brains

Ounce for ounce liberal humans have significantly more morons in their brains

"In designing brains, nature has two parameters it can play with"

"Designing"? "Playing"? I thought this process, i.e., nature, was mindless, chaotic chance. If so, then these words sound fanciful, magical.

Up next, perhaps a similar study on hares? Beetles?

I’ve owned macaws and they are said to have the mind of a three-year-old human. Of course, they are largely fun-loving playful mimics but they are very bright if you understand what is important to them. They learn mostly by cause-and-effect and they enjoy drama which is why they learn curse words quicker than other words. If you can make learning a cause-and-effect game, they’ll pick it up.

They make fun pets if you have the time to give them the regular interaction they require.
