El zarapito picolargo figura en la lista de especies de aves altamente preocupantes del Servicio de Pesca y Vida Silvestre de EE.UU., así como en la de especies de especial preocupación en Canadá. Algunas poblaciones han disminuido drásticamente en las últimas décadas, amenazadas por la pérdida de hábitat de cría, sobre todo de pastizales, la urbanización del hábitat agrícola y la caza.

Over the last 15 years, many collaborators, including All Hands Ecology’s Nils Warnock, have been using lightweight satellite transmitters to track curlews from a variety of breeding and wintering areas and have achieved impressive coverage that spans most breeding states and provinces and most of the wintering range.

However, a large knowledge gap remains along the coast of California where many curlews winter but few of previously tracked birds have been documented. Now All Hands Ecology is helping to fill this gap in a collaborative study with Dr. Autumn-Lynn Harrison of the Smithsonian Migratory Bird Center (https://nationalzoo.si.edu/migratory-birds), David Newstead of the Coastal Bend Bays and Estuaries Program (Texas), and Dr. Jay Carlisle of Boise State University’s Intermountain Bird Observatory.

In February, with assistance from colleagues above, All Hands Ecology researchers Nils Warnock, Scott Jennings, and David Lumpkin helped capture two curlews at Limantour Beach and fitted them with 9.5 g solar-powered satellite tags.

Esperamos seguir la pista de estos zarapitos hasta las zonas de cría para ver dónde encajan en el panorama más amplio de la conectividad migratoria de la especie (para algunos datos recientes sobre los desplazamientos de los zarapitos, véase https://www.boisestate.edu/ibo/curlews/).

All Hands Ecology Avian Ecologist David Lumpkin releases a Long-billed curlew captured and tagged at Limantour Beach, Marin County on 2/20/20 for a GPS movement study.
