Design animation for home page

We are designing a website for a client and he wants animation on the homepage of website. Basically when the page loads there should be an eagle flying and picking the globe (planet earth) with its claws, symbolic of company logo, an eagle with claws on globe. We dont want flash animation for obvious reasons, its fading out, HTML5 is preferred or you can make recommendation as long as its up to standard. You would also have to share working raw files (e.g. psd etc) in addition to the final work. Please provide your animation portfolio for review.
