Heavy overcast skies, wind W 5MPH, 39F; sunset time 5:25PM
On Crow Patrol with first stop up by water tower and Storrow Park, then moved down to lower Marston Street. Crows started arriving minutes after sunset time with multiple flight burst loops out over Marston Street. Image at 26 minutes post sunset.
The Crows filled the air with rowdy vocalizations until the action slowed way down. Image at 29 minutes post sunset time.
The Crows finally quieted down and settled into the roost for the overnight. Image at 95 minutes post sunset time. Amazing 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.
