Shy Rays Swarm New York Waters

Drone footage has revealed large gatherings of cownose rays in waters off Southampton, Long Island. These shy, non-aggressive cartilaginous fish, measuring up to 3ft in wingspan, typically visit the area during warmer months. Their presence in such numbers has led scientists to consider potential shifts in their migratory patterns.

Experts, including those from Florida State University and Adelphi University, suggest that rising ocean temperatures, linked to climate change, could be encouraging the rays to migrate further north than historically observed. While cownose rays have been common in Long Island waters for at least 25 years, their appearance in large groups, termed a 'fever' of rays, might be influenced by water temperatures nearing 70-79F.

Researchers also emphasize the role of modern drone technology in increasing public and scientific visibility of these marine animals. While cownose rays have been documented in New York since the 1800s, advances in aerial observation make everyday wildlife activity more apparent. This technology aids in studying their movement and estimating population sizes, particularly for species that frequent the water's surface.
