See a California Condor.
No, really, you gotta do it. It is lump-in-the-throat worthy. I don't know why big animals are so special, but they are. Condors are like IMAX birds.
Their wing span is 9 feet or so. They have four at the Santa Barbara Zoo and it was worth every penny of the $11 entry fee just to see them.
There are also some cute penguins in case you like your birds smaller and with less flight.
You can also pay another $4 to take the train. The train tours areas of the zoo you don't normally get to see, like the piled-up crap behind the cages, the cages behind the other cages, and the spare train. I wouldn't say it is worth the price, but you do get to sit down, so there's that.
