On Crow Patrol with first stop along the banks of the Merrimack River at end of North Main Street in North Andover, observing light incoming flight streams at sunset time. Moved over to Marston Street and observed endless incoming flight streams coming in from the NE.
Saw large numbers of Crows gathering and loudly vocalizing in tree tops along lower Marston Street, mostly opposite Marston Medical building, but not on south side of street.
The roost filled in quickly and with only a few minor flight bursts.
By 52 minutes after sunset time, the overall roost area settled down and became very quiet. Great action!
For the 2022 Audubon Christmas Bird Count (CBC) for the Andover Circle, this separate Crow Count was 13,750 Crows. In 2021, the CBC Andover Circle Crow Count was 12,250. Many thanks to Donna Cooper who coordinates and compiles the Andover Circle each year!
Note on counts/estimates: we are now using improved methods for counting the large number of Crows while streaming, staging, and in the roost. For all images, we use both a modified open source counting software program, as well as a hand count approach, while outside next to the roost, to carefully document our observations and to significantly increase reliability and accuracy of the presented numbers. Please refer to our new roost counting guide on main page.
