Mono Lake’s California Gulls safe for the season

A mile of citizen-funded solar-powered electric fence is up and running, protecting Mono Lake’s nesting gulls—one of the three largest colonies in the world—from mainland predators. The fence is the result of a year and a half of planning by the Mono Lake Committee and California State Parks along with other agency partners, a dedicated local installation team, and generous funding from Mono Lake supporters across the country.

The temporary electric fence stretching one mile across the landbridge has 11 motion-activated wildlife cameras with infrared nighttime flash capability along its length. In late April, camera #5 documented a coyote walking the fence line, confirming that the fence is functioning as a coyote barrier. Mono Lake Committee wildlife camera photo.

Why is the temporary fence—which will be removed when nesting is finished—needed? Five years of drought lowered Mono Lake seven feet, shrinking the protective moat of water between the lake’s north shore and Negit Island and adjacent islets—exposing a landbridge that allows coyotes access to the lake’s long-established nesting colony of California Gulls. Last summer signs were found on a few of these islets that coyotes had indeed walked the landbridge and then swum the remaining 500 feet or so of shallow water to prey on eggs and chicks, disrupting nesting and causing gulls to be suspicious of returning to these sites in future years.

The temporary electrified fence protecting Mono Lake’s nesting California Gulls has been up and running for about three weeks now. After a long and snowy winter the gulls’ calls signal spring’s arrival, and it’s gratifying to know that as they build nests and lay eggs out on the islands, they are protected from coyote predation.

The fence stretches for about one mile across the landbridge, and is made up of five sections that overlap—an electrified long middle section, two shorter electrified sections at the ends near the water’s edge, and two passive sections at (more…)

Mono Lake Committee launches #LongLivetheGulls campaign

This spring, when tens of thousands of California Gulls return to their island nesting ground at Mono Lake, they will be in danger of having their once-safe colony raided by coyotes. During the drought, Mono Lake dropped 7 vertical feet—exposing a landbridge to the gulls’ nesting islands. It’s hard to believe that all of this snow and rain we’re getting won’t fix the problem naturally. The lake is rising, but the snow we’ve gotten this winter won’t melt and raise the lake in time to protect them when they lay their eggs in April. Help us put up a fence to save the gulls before it’s too late!

As Mono Lake lovers know, Mono Lake is critical habitat for millions of birds. Many of these birds stop by on migration for the shrimp and fly soup buffet, but there are a few that have made Mono Lake their annual summer home getaway to nest and reproduce.

California Gulls are one of the most iconic seasonal residents. Gulls nest out on Mono Lake’s islands, laying eggs and raising chicks to fledging there during each summer. The “island closure” takes effect from April 1st to August 1st in order to protect the thousands of gulls and their chicks, so people must stay at least one mile away from (more…)

You are on a rocky volcanic island surrounded by an alkaline sea. Your only protection from the high-desert sun is your khaki-colored Mono Lake Committee logo bucket hat. It’s also your only protection against the frenzied California Gulls flying every which way and trying, as you suspect, to whitewash you with an airborne “splat!” (more…)

Each spring the Mono Lake Committee assists PRBO Conservation Science in doing a California Gull nest count on Mono Lake’s islands. PRBO, whose mission is to conserve birds and other wildlife, has been monitoring the population size and reproductive success of California Gull (Larus californicus) at Mono Lake since 1983. (more…)
