One can find many seasonal or vernal pools throughout the College Sanctuary south of College Street and west of South East Street. They typically hold breeding populations of wood frogs, spring peepers, and various salamanders.
Woodpecker excavations in trees throughout the sanctuary woods are evidence of several species at work, including pileated, hairy, and downy woodpeckers. The now extinct ivory-billed woodpecker on display in the Extinction: The Human Factor at the Beneski Museum of Natural History is superficially similar in appearance to the local pileated woodpecker.
