Most waterfowl have now left Hinsdale but juvenile Barrow’s Goldeneye remains, plus a male american wigeon and a single great blue heron. Also, 5 crows flying north over the setbacks. Did not call, but based on their shape and flight I am convinced that they were fish crows. Becoming more and more convinced that there is a regular early morning northward passage over the setbacks in mid-late March. Since these birds do not call much nailing this down is a problem. Pam Hunt and others had 4 (I think) FICR passing over yesterday. Puzzling to say where they are headed to as we are already close to the northern edge of their breeding area. However, the more I see of this the more I become convinced that there is a hitherto undetected regular northward passage of this species up the Connecticut Valley in early spring. I suspect that this passage (if I am right) has been largely assigned to American Crows. Wish that they would call more often!
