Some of them dive bombed the food dish - grabbing food as they passed or landing in the dish to feed. Others hung from a branch above and reached down to grab some food, using their feet and/or their thumbs as anchors.
Still others landed below the dish and climbed up a branch, using their thumb like a hook to pull them up to the food dish or hung from the dish's platform itself, using their thumbs to hold on while using a foot to bring the food to their mouths.
More than anything, watching them fly and climb made me think of dragons. I suspect there's a reason dragons tend to be portrayed with leathery bat wings. The movements of the bats shoulders as they climbed really had the look I remember from CGI dragons in films.
I never realized how articulate their thumbs (the bit sticking out the top of the wing) were. In fact, I've never given consideration to the fact that their wings are - quite literally - their hands (there's the thumb up top and the four wing bones are labeled as fingers). It's amazing watching them move.
Here's a short video I took. I apologize for the poor quality. The cage was dark so I had to lighten the video quite a lot for the bats to stand out. The song playing is "The Goya Discovery" by Derek R. Audette.
