I'll post some of the photos later, but here's a Charismatic Mammal:
and a coupla Deviantart pics
There was an enormous flock of starlings, going after these weird blue-violet grape-looking clusters hanging off the palm trees. I was at the capybara exhibit, which is a covered walkway extending into the water, surrounded by these fruiting palm trees. And as the capybara sedately munched duckweed, and I tried to get a zoomed shot of his weedy muzzle, there was this sudden cacaphony, and like a scene from the birds, starlings were suddenly descending everywhere, on these trees and the fruit. The sound of starling poo on the roof was like rain. The capybara and I both froze, gazing up like...well, large startled rodents, which reflects better on him than on me...and after a minute or two, while I fumbled to take photos (I despise starlings, but anything's interesting in a horde) they flew yammering off. I looked at the capybara. He dropped his head and looked at the duckweed. I said "Okay, then," and moseyed off to photograph tortoises.
All in all, a good day.
