Peacocks have the run of the mill of the place. They fan themselves out on the lawn and stretch out on shady patios - quite a greeting for people just walking through the entrance. Thankfully, they're very nice.
The massive waterfall at the edge of Japanese Garden was one of my favorite features. The drop must have been over 25'. Ferns, rhododendrons, and maples share space with massive boulders. Great inspiration for gardening in Northern California.
