Timing (including late fall & early winter) likely rules out frogs.  Has to be a bird or mammal I think.

You can check out local amphibian calls on the online amphibian guide of the Peabody Museum:


If the calls are produced by amphibians, your best bet this time of year would be Spring Peeper, American Toad, or on an exceptionally warm April night, Grey Tree Frog. Amazingly, I've heard tree frogs calling in my Torrington backyard on at least three nights already this year! The latter two species' calls sound more like a trill than a "peep" though.
