Spring is the time when birds are establishing territory and calling to mates. Over the next couple of months a variety of birds will be stopping in Hannibal on their migrations further north or establishing nesting sites here. It’s an exciting time to listen and observe the birds at Sodalis! Bring binoculars and check out the Merlin Bird App for learning bird calls. Beginner and experienced birders welcome. This is an easy, slow walk on the flat parts of the paved trail and covers about a mile.
