The Western Snowy Plover nests on open sand, so it’s extremely vulnerable to human impacts, both direct and indirect. For example, the kelp that is washed ashore is browsed upon by many insects and crustaceans. These invertebrates are a primary food source for plovers and other shore birds, so “cleaning up” the wrack removes a key element in the food chain. A more indirect impact: the population explosion of crows and ravens — caused by the abundant food sources offered by humans — has greatly multiplied a major plover predator.

At current counts, there are less than 2500 Western Snowy Plovers throughout their coastal range (a population of 3000 is the minimum goal) and their habitat continues to shrink. So if you see a cable fence on your local beach, be sure to stay out of the nesting zone to give these vulnerable (and adorable) birds a chance to breed and thrive.
