The antenna of an Argos satellite tag extends past the tail feathers of a female American robin as she feeds a worm to her hungry nestlings on a front porch in Cheverly, Md., Sunday, May 9, 2021. A new antenna on the International Space Station and receptors on the Argos satellite, combined with the shrinking size of tracking chips and batteries, are allowing scientists to remotely monitor small animal and songbird movements in much greater detail than ever before.
