Curlew Project

PROJECT OVERVIEW

Joining a continent-wide effort to map a charismatic species’ migration.

Long-Billed Curlews are North America’s largest shorebird. They breed in grasslands across western USA and Canada. They face multiple conservation challenges, with each subpopulation having unique regional needs. Identifying and delineating these populations is a vital first step in creating a continent-wide understanding of how to best protect this charismatic species.

THE PROBLEM

How to track western Wyoming curlew winter sites and migration routes?

Long-billed Curlews are North America’s largest shorebird. They breed throughout the central and western portion of the continent, nesting in rangeland, farm fields, and pastures. In late summer they migrate south and winter along coastal California, in Mexico, and the Texas Gulf Coast. They have experienced significant population declines, but across such a large range, there are multiple sub-populations that face threats and conditions unique to their region. Identifying and delineating these populations is a vital step in creating a continent-wide plan to protect this charismatic species.

THE SOLUTION

Join other conservationists and track these birds with satellite tags.

In March of 2020, Covid 19 kept RCF from placing four satellite transmitters on Clark’s Nutcrackers in Yellowstone National Park. Rather than wait a year and try again, we decided to deploy the transmitters on Long-billed Curlews, a species that breeds on Jackson Fork Ranch.

RCF teamed up with the Intermountain Bird Observatory to attach the transmitters onto Long-Billed Curlews at Jackson Fork Ranch. We captured incubating curlews on their nests and then banded, measured, and weighed each curlew, before fitting it with a transmitter that tracks its movements using the ARGOS satellite system.
