Scientists have documented for the first time a bat, specifically the greater noctule bat in Europe, catching and eating a bird in midair during migration, revealing an unexpected predator of high-altitude migrating birds.

Thousands of wild birds, particularly snow geese and other 'light goose' species, are dying from avian flu in Idaho's Treasure Valley, according to the Idaho Department of Fish and Game. The outbreak, caused by the highly pathogenic H5N1 strain, has led to mass die-offs at locations like Fort Boise and Lake Lowell. While the impact on overall bird populations is minimal, the public is advised to report sick or dead birds and follow safety precautions when handling them. The flu poses risks to humans and pets, though human cases in Idaho have not been reported.

A study has found that radio waves emitted by radio and television broadcasting and CB radio can disrupt the magnetic compass of migratory birds, while those used in mobile communication networks do not. The researchers theorize that the magnetic compass sense in these birds is based on a quantum-mechanical effect located in their eyes. The study determined the upper bound frequency that disrupts the birds' magnetic compass and found that frequencies above 116 megahertz have only a weak effect on their magnetic orientation. Understanding magnetoreception is crucial for protecting migratory birds and avoiding electromagnetic radiation that can drive them off course.
