  skos:definition "The passenger pigeon (Ectopistes migratorius) was once probably the most numerous bird on earth but became extinct through an extraordinary case of massive overhunting and habitat loss. This striking blue-gray pigeon, closely related to the mourning dove, was highly social, living in huge flocks across the great deciduous forests that once covered eastern North America.
