Telegraph Hill (elev. 275 ft (84 m)) is a neighborhood in San Francisco, California. It is one of San Francisco's 44 hills, and one of its original "Seven Hills". Telegraph Hill is primarily a residential area, much quieter than adjoining North Beach with its bustling cafés and nightlife. Aside from Coit Tower, it is well known for its gardens flowing down Filbert Street down to Levi Plaza. Today Telegraph Hill is known for supporting a flock of feral parrots, primarily red-masked parakeets (Aratinga erythrogenys), descended from escaped or released pets. The flock was popularized by a book and subsequent documentary (2003), both titled The Wild Parrots of Telegraph Hill.
