My all time favorite creatures at the Austin Aquarium are the Rainbow Lorikeets.  They love to examine you and your belongings up close.  They will land on you in a friendly way and check you out.  They seem to be always in motion, making it challenging to get a good photo.  My small camera is interesting to them, so they usually want to experience it by touching it with their beaks.  I will normally try to spend as much time as possible inside their enclosure at the Aquarium.  It is so much fun to hang out with these awesome birds.
