A flock of wild parrots make their home on Telegraph Hill just below Coit Tower. You may hear them squawking noisily as they fly overhead.
Coit Tower, the white monolith atop Telegraph Hill boasts some nice views and a notable collection WPA-era murals in its lobby. Walk up from here or wait until the end of your tour and take Muni Bus Number 39, which stops on Union at Columbus.
