Description from the artist’s Deviantart page:

“Our half-cat, half-bird friends possess a lot of different features in colors and forms, but there is also some similarities.

The first family is the most common : Eaglegriffin. They usualy have an athletic body and are oftenly related to strength.

Then we have Hawkgriffin. they can be recognized easily by their complet lack of fluff from their feathering. They’re agile by nature, compared to the average. I’m going to make some ponies grumpy by this statement, but until today, hawkgriffin own the highest flying top speed records ever registered.

The last and rarest are Owlgriffin. They have the most peculiar body which make them easy to spot. They possess large ears and deep black eyes, their plumage is more dense and most of all, their talons are composed differently, 2 front fingers istead of 3, and 2 thumbs. Through the ages, owls were oftenly refered as wise advisors and knowledge keepers. Oh and yeah, they can rotate their head 270 degrees … creepy !
