WarcraftPets.com has a couple nice screenshots of the rustberg seagull as well as a preview of the possible armadillo companion!
the source of the armadillo is still unknown, however players have confirmed that a vendor in Tol Barad named Brazie sells the seagull for 4g. there may be a reputation needed to purchase the bird pet in future beta patches or upon the expansion release.
the seagull's as one would expect. i was hoping for a baby seagull but i'll take what i can get. :P the armadillo on the other hand, baby or not... this guy is adorable!
(please give him a rolled up ball animation, please give him a rolled up ball animation, please give him a rolled up ball animation, please give him a rolled up ball animation)
