The BBC has a number of walks at Mt Auburn through the peak migration,
6:30 AM in April and 6:00 AM in May. Look forward to seeing you there.
We did not see the Great Horned Owl in the Dell, however I stopped by Fresh Pond (off Huron Ave) and the
baby and momma owls were easily seen. I haven't seen these owls/nest posted - they are near the intersection of
Huron Ave and Fountain Terrace. The Cambridge parks folks have done a great job cordoning off an area to assure that
people don't bother the owls too much.
