Overview
Perhaps better known for the tufa towers and western
water wars, this salty lake along the east side of the Sierra Nevada
Mountain Range provides habitat for billions of alkali flies and brine
shrimp. The flies and shrimp, in turn, are food for many thousands of
grebes, ducks, gulls, shorebirds, and other species, some 300 species
and millions of individuals in all.
Each spring, about 50,000 California Gulls breed on the
big island in the lake, and about 400 endangered Snowy Plovers nest on
the alkali flats on the northeast shore. In mid-summer, thousands of
Wilson's Phalaropes and Red-necked Phalaropes stop during the migration
south to fatten up; and in the fall, nearly two million Eared Grebes
join the food fest. Ducks, geese, and Tundra Swans also stop over
during migration.

Description
Mono Lake is set in a picturesque valley on the east
side of the Sierra Nevada Mountains in eastern California. Like many of
the lakes east of the Sierras, Mono Lake sits in an enclosed basin with
no natural outflows, and as a result, the water is salty. Springs in
the lakebed are marked by tufa towers, which are a calcium-carbonate
precipitate resulting from mixing calcium-rich spring water with
carbonate-rich lake water. As water levels have declined, some tufa
towers were exposed. Bird rest and nest on the tufa towers. There is
also a large island in the lake that ground-nesting birds (especially
the California Gull) use for nesting. |

Because the water is salty, there is no riparian fringe
on the lake except where streams flow in. There is a stream at the
County Park on the northwest side of the lake with cottonwoods,
willows, and other trees and shrubs, and there is a bit of a marsh
where the stream flows into the lake. Otherwise, the lake edge is
barren or has a few salt-tolerant shrubs. Above the lake, the dominant
plant in this high-elevation desert is sagebrush, and there are pines
in the mountains surrounding the lake.
The South Tufa Towers State Reserve,
located on the southwest side of the lake, protects one of the largest
collections of tufa towers. A self-guided nature trail runs down
through the sagebrush scrub (sagebrush with lots of greasewood,
saltbush, and rabbitbrush) to the edge of the lake. The shrubs
along the trail make good birding for landbirds (e.g., Rock Wrens, Sage
Thrasher, Loggerhead Shrike, Red-tailed Hawk, Northern Harrier, Common
Nighthawk, Black-billed Magpie, Sage Sparrow, and Meadowlark). |

The lake and tufa towers can be covered with waterbirds
(phalaropes, grebes, gulls, waterfowl, and a few predators like
Peregrine Falcon and Osprey). The shoreline is a good place to look for
shorebirds (American Avocet, Marbled Godwit, Western Sandpiper, Spotted
Sandpiper, Willet, and Black-necked Stilt). During migration, Ruddy
Ducks, Green-winged Teal, Mallards, Canada Geese, and Tundra Swans can
be common.
The Mono Lake County Park, located on
the northwest side of the lake, has an easy trail and boardwalk that
runs down through cottonwoods and willows to a marsh at the edge of the
lake (with more tufa towers). From the end of the boardwalk, you can
see phalaropes, waterfowl, and grebes feeding in the water, and
shorebirds feeding on the little delta at the edge of the lake. The
cottonwoods and grassy areas in the park, proper, also make for good
birding (watch for flycatchers, tanagers, and warblers). Common Snipe
breed in the wet meadows, and Red-Winged Blackbird, Song Sparrow,
Common Yellowthroat, Killdeer, Snowy Egret, and Green-backed Heron are
common. |

Trip Notes
August 28, 2005
We stopped by the Mono Lake Tufa Reserve at about 1100 hrs to do a
little birding on our way home from a week of backpacking in Yosemite.
We saw a fair number of birds, but it was fairly quiet, although we did
see two Long-tailed Jaegers (adult and juvenile) that had strayed over
land during their fall migration to the Antarctic.
Clear, calm, 75 degrees. Long-tailed Jaeger (adult and
juvenile), Common Raven, Sage Thrasher, Brewer’s Blackbird,
California Gull, Brewer’s Sparrow, Green-tailed Towhee, Osprey,
Eared Grebe, Killdeer; sceloporous (sagebrush?) lizard, least chipmunk |
