Lake Merced: San Francisco’s Birding Jewel
By Angie Geiger
Located in the southwest corner of San Francisco, Lake Merced is one of only three remaining freshwater lakes in the city. There are multiple excellent birding areas within this 614 acre park. At 267 species, Lake Merced is the number two hotspot in San Francisco, (not including the Farallon Islands) according to eBird. It is home to quite a few breeding birds, the wintering grounds for numerous others and an important resting stop for many migrants.

While it is possible to see birds anywhere around Lake Merced, the three most commonly birded areas are “the concrete bridge”, Sunset Circle, and Harding Park. All are directly on the lake and offer excellent views of the waterfowl on the lake, as well as lots of songbird activity in the reeds, trees and shrubs surrounding the lake. All three have parking lots and are also accessible by bike and public transportation.

The concrete bridge area can be accessed on the east side via a small parking area on Lake Merced Blvd. or on the west side via John Muir Drive. If Gull identification is one of your avocations, this is the place to practice in the winter. Gulls of all ages are often on land and/or perched on the railings of the bridge for close-up views. Most common are Western, California, Mew and Glaucous-winged, with the odd Herring and Iceland Gull sometimes in the mix. Some years, Bonaparte’s Gulls have been spotted foraging on the lake in winter. In addition to the gulls, there are many species of Ducks and Grebes in among the Coots on the water. Breeding plumaged Ruddy Ducks can be seen with their neon-blue bills and the concrete bridge is a good place to watch the courtship behavior of Grebes. Both Western and Clark’s Grebes breed here, sometimes with each other producing consternating hybrids. You will spot begging offspring throughout the Spring and Summer. Once in a while the Concrete Bridge area attracts a Common Galinule. In addition to the Waterfowl, this area is also fairly reliable for Sora and Virginia Rail, more often heard than seen. Summer is a great time to practice your Swallow identification skills – six Swallow species can reliably be seen over the lake and perched on trees at the water’s edge. On the east side of the concrete bridge is a slight tree-covered hill featuring a Penguin sculpture.…
