Which bird has the largest brain?

I believe I read that Parrots have the largest brains for body ratio compared to other birds. Which makes sense, since they are also the only bird able to talk. Maybe the mocking bird can come close

“Anatomically, a bird has a relatively large brain compared to its head size. Birds in the crow family (corvids), and parrots (psittacines) have been shown to live socially, have long developmental periods, and possess large forebrains, and these may be expected to allow for greater cognitive abilities.”

Oh, I misunderstood. I did find this chart and it seems Ostrich may be the winner. http://serendip.brynmawr.edu/bb/kinser/images/jerison1.gif

I found that chart as well, but it only contains a few bird species.

I would think if there was a bird with a larger brain than it would’ve been chosen instead of the ostrich.

I’m not giving guarantees, but I’ve heard it’s the bowerbird. Fascinating birds, by the way!

@longgone that’s a very interesting article. Thanks for posting that.

I’m thinking it has to be some large bird of prey or a large scavenging bird.

I also keep finding that ravens have “among” the largest brains of all birds. Always “among” though.

Probably what ever the biggest bird is.
I figure that is the Ostrich.
So I also figure the Ostrich has the biggest brain.

@Afos22 You’re welcome.
