I saw an image macro on facebook the other day that started me thinking;

I tried to look into it and I found two separate styles.

Pottermore Style

Book Style

Neither of these to me looks anything like a raven, besides being bird shaped.

Is the crest meant to show a raven, or just some sort of bird?

I've struggled to find an 'official' rendition of the crest, and this is the best I could find, but I've seen plenty of fan-mad crests that do show a raven, seemingly correcting this 'mistake'.

So why does the Ravenclaw symbol show an eagle, and not a Raven?
