Revealing migration strategies of high latitude breeding myrtle warblers

Presenter: Steph Szarmach, James Smithson Postdoctoral Fellow, Smithsonian Migratory Bird Center; AOS Student Research Grant, 2022 Host: Robert Driver, research scholar; Duke University School of Medicine Multi-sensor geolocators that measure atmospheric pressure enable tracking of small songbirds at a fine scale not previously possible using traditional light-level geolocation. In this talk, I will present my work using multi-sensor geolocators alongside stable isotopes to characterize at a high resolution the migratory journeys of myrtle warblers (Setophaga coronata coronata) breeding at high latitudes of northwestern North America. I will discuss the unexpected results of this study in the context of previously proposed hypotheses regarding the factors shaping migration routes and will demonstrate the advantages of geolocation using barometric pressure. 2025 AOS Student Research Grant Fall Series, Seminar 11 Recorded 17 November 2025
