Hi Lance:
The Sibley flight path indicated is basically a center line. The
birds do spread out/wander on either side of the center line.
The only Cackling Goose subspecies confirmed in Maryland, so far, is
B. h. hutchinsii - "Richardson's" Cackling Goose"; however, others
could still show up here.
Hope this helps ...
Phil
