Shorebirds in August? I’d been told there was a robust migration during that time, but hadn’t tested the validity of such until a week ago. Three other young ladies joined me to do a count at the Salt Creek Wildlife Management Area near Tremonton Utah. And boy did I need their younger eyes and energy as we were inundated with shorebirds- avocets, stilts, curlews, greater and lesser yellowlegs, dowitchers, marbled godwit, western sandpipers, killdeer, and a flock of small peepes (short for small sandpipers).

Myriad other magnificent migrants joined the mixed flock- numerous duck species, juvenile black crown night herons by the dozens, herons, egrets, ibis, terns, etc., but they don’t qualify as shorebirds, so we enjoyed their presence, but they didn’t make the list.

A few other non-migrants were noteworthy- a burrowing owl that posed beautifully on a fence post emitting constant chatters, and a very fat, mature western rattler with many buttons on its tail./ The Salt Creek WMA is a jewel that gets few visitors given its “out there” location competing with the 80 thousand acre Bear River Migratory Bird Refuge next door, which boasts an outstanding visitor center, offering many resources and educational programs.

This was the first official fall shorebird survey conducted in 30 years at roughly 200 sites across 11 western states. These surveys fill a critical three-decade data gap in our understanding of migratory shorebird populations and their distribution. The results will inform management and policy efforts to ensure there are resources to support birds and the places they need during their migratory journeys.

The survey was organized by the Sageland [Collaborative] organization, Utah Division of Wildlife Resources, and several others, conducted by volunteers and biologists via airplane, vehicles, ATVs, boats and on our feet. This survey will occur for the next three years, during the same week each spring and fall, to coincide with the peak shorebird migration across the region.

We’re part of the Great Salt Lake ecosystem, whose wetlands support nearly one-third of the global population of Wilson's phalaropes, more than half of American avocets, 37 percent of black-necked stilts, and 21 percent of the North American population of snowy plovers.

Shorebirds are a diverse group of birds including sandpipers, plovers, avocets, oystercatchers, and phalaropes. There are approximately 217 recognized species globally, 81 of which occur in the Americas for all or part of their lifecycle with 52 species breeding in North America, many of whom visit Utah.

Shorebird are the endurance marathoner winners, some migrating 20,000 miles a year. Their remarkable hemispheric travels coincide with peak abundant food. In their global pursuit of food and breeding grounds, home is nowhere, yet everywhere. As a result, shorebirds are difficult to track, monitor, and protect. /Shorebirds are among a few groups of birds showing the most dramatic declines. Their decline began in the 1800s, in part due to market hunting. As humans have continued to alter the landscape, shorebird populations have further decreased, with declines increasing rapidly in recent decades.
