Wild NYC: Springtime Water Migrations

In this episode of The Brian Lehrer Show, host Brian Lehrer explores the hidden natural rhythms of New York City during spring, focusing on aquatic migrations in part one of a two-part series. The discussion centers on the arrival of baby American eels, known as glass eels, which journey from the Sargasso Sea to New York’s waterways, marking a pivotal moment in the city’s ecosystem. Chris Bowser, an estuary educator from the New York State Department of Environmental Conservation and Cornell’s Water Resource Institute, explains the life cycle and ecological importance of eels, while urban botanist Marielle Anzalone highlights the role of horseshoe crabs in coastal spawning and their connection to migratory shorebirds like the red knot. The episode emphasizes New York City’s identity as a city of islands with over 500 miles of coastline, underscoring the deep interconnection between urban life and wild nature. Listeners are invited to share photos of seasonal changes via Instagram using #BLWild and to call in with questions about these migrations. The episode also features educational resources for teachers, including lesson plans from the National Estuarine Research Reserve and the Eels in the Classroom program, as well as community science initiatives like those at Fresh Kills Park. A poignant moment comes when Chris Bowser describes the ethereal beauty of glass eels—nearly transparent, refracting light into rainbows—and frames them as symbols of ecological connectivity and hope. The episode closes with a reminder that the city’s natural cycles are not just local but part of a vast, ancient web of life stretching across continents and millennia.
