The Crow Patrol was established during the 2017-2018 winter crow roost season. Craig Gibson, Bob Fox, and his wife Dana Duxbury-Fox got the ball rolling with an expanded fascination of the local winter crow roost along the Merrimack River in Lawrence, MA. They spent over 160 observation nights during the winter of 2018-2019 observing, monitoring, documenting, and photographing the amazing crows. Craig has already had over 60 observation nights, with a constant eye on both staging and roosting patterns, during the 2019-2020 season. Many others have participated, and all are welcome to become members of the Crow Patrol!
