Angry Birds? Seagulls Implicated in Baby-Whale Deaths

Hundreds of baby whales died off the coast of Argentina between 2003 and 2014, and seagulls may have played a role in their deaths, a new study suggests. Gull harassment of right whales off Argentina's Península Valdés has been observed since the 1970s. Since then, researchers from universities and conservation institutions in Argentina and the United States have monitored the gulls' behavior.
