The Monterey Bay Aquarium is a lovely place to visit -- but if you can't make it to the Bay Area, you can catch the penguin exhibit in HD on their Penguin Cam. Today's feeding times are 10:30am and 3pm Pacific. Right now, an hour past their feeding time, the birds are acting a little lethargic, waddling around and checking each other out, generally doing typical penguin stuff.
But why ask me? Watch it live (7am–5pm Pacific):
The Aquarium explains a little about these African blackfooted penguins' behavior:
Watch carefully and you might even see them communicating with each other. When penguins flap their wings or bow their heads, they're telling each other how they feel. Throwing their heads back and wings out means "I'm happy." Leaning forward and opening their beaks means "Go away."
I just saw two of them do the "I'm happy" dance. Just wait for 3pm (Pacific) and you'll see a lot more of that.
