The only thing I can find are morphs for a parrot and a raven.

Vista Internet used to have lots of birds and animals, not sure if any were morphs for the eagle though. I think they were mostly individual figures.  They've since closed though.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
