Although it would be a welcome addition to an Adirondacker’s book shelf, “Adirondack Wildlife” is really meant to be thrown into a day pack, dog-eared and filled with quickly-scribbled notes – a field guide in the true sense of the word. A make-shift ruler in both inches and centimeters can be found on the front and back inside covers and amateur biologists can check off sightings on a species checklist in the back of the guide.
