I would choose a woodpecker.

Is this idea from my thread?

It's okay.

I'll be a humming bird because I'm always hyper and I talk pretty fast when I saying something to my friends. My name will be Harper and my feathers are tropical blue. my eye colors are orange. Enemies are dogs and foxes. 

Disney made sure to only use mammels.

I would be an owl or a hawk.

They're mentioned in old Shanmanic thougts  just like the pretty wild canines it's the Swallows I'd choose.

I know Zootopia is initially about mammals, but I would like to see canaries, owls, penguins, ratites, or shorebirds (especially a ruff or godwit)..
