Last year at this time, one observer recorded over 21 different species of warblers in a three-day visit. Large flocks of American gold finches and pine siskins are prevalent also. One can also observe nesting wood ducks. Many of the sanctuary nest boxes are occupied by wood duck hens incubating their clutches of eggs. The birds often leave their boxes in the morning or afternoon and return at dusk.
Visitors hiking the trails also commonly view moose and white-tailed deer.
Spring is a wonderful time to hike the network of trails that meander through the wood lots, wetlands and prairies in the sanctuary. Along most of the trails are bluebird houses where hikers see nesting bluebirds, tree swallows and house wrens. Many of the fruit-bearing trees and shrubs are just beginning to bloom or will be very soon. The air is filled with the sweet aroma of blossoming flowering crab, apple and plum trees. Honey bees, butterflies and other nectar and pollen-seeking insects are buzzing with activity everywhere.
