The Essex Art Center (essexartcenter.org/) will be mounting an exhibit in January 2019. This video is the first of mine to focus on the winter crow roost.
Each winter crows from Canada fly south to warmer winter locations. One of these locations is Lawrence Ma where in December the local Corvus inhabitants are joined by their northern neighbors. The murder swells from five thousand to sixteen thousand birds. The crows gather to settle at the nighttime roost in the trees, on the ground, and on electric lines along side the Merrimack River.
