Modeling realistic bird w/ feathers

Hey guys, I’m trying to create a realistic bird that has feathers all over it (mountain blueburd) and I’m running into a little bit of trouble.
I was wondering if there are any good bird modeling tutorials out there, all I’ve found are either just wing rigs, low poly birds and non realistic birds without feathers.

Heya, there’s this one with feathers:

But it’s pretty chubby and doesn’t have big wings.

Well I’m trying to make a realistic looking bird. That part where the big feather is made will help quite a bit.

What about this thread? Bioluminescent Macaw

Thanks, I’ll review his work.
