Rare Itinerant Breeders: How Researchers Discovered the Woodcock’s Unique Breeding Strategy

GPS tracking reveals American woodcock re-nesting movements across the Atlantic FlywayIn this episode, AJ and Gabby talk with Colby Slezak, a recent PhD graduate from the University of Rhode Island, about a surprising breakthrough in American woodcock ecology: evidence that female woodcock can be itinerant breeders.Colby explains how new GPS tracking technology, combined with on-the-ground nest checks through the Eastern Woodcock Migration Research Cooperative, helped confirm a behavior that had long been suspected but rarely documented. When nests fail, some female woodcock will travel long distances and attempt to nest again elsewhere, sometimes multiple times in a single spring.We unpack why woodcock have such an extended breeding season, what low nest success looks like on the ground, and how constraints like GPS tag size and battery life shape what researchers can learn about breeding ecology. Colby also reflects on the moment he and his colleagues realized their data supported this long-standing theory, an unexpected discovery that reshaped how researchers understand woodcock breeding behavior.The conversation then shifts to Colby’s brief time with the U.S. Fish and Wildlife Service and what federal workforce reductions and buyouts may mean for conservation capacity, long-term partnerships, and the institutional knowledge behind migratory bird research.To learn more about the Eastern Woodcock Migration Research Cooperative, visit woodcockmigration.org.Listen to past episodes here: Project Upland PodcastIf you want to support independent journalism, check out the Project Upland Podcast Patreon.
