The cold weather of the last week has silenced the frogs for now. It seems eerily quiet in the evening and at night without them; about all I hear now is the woodcock, still faithfully performing his display at twilight, and one ruffed grouse drumming in the distance. The forecast does not look encouraging, with highs in the 40's-50's and nighttime lows from 25-30 for at least the next few days.
My pet theory of the day is that a rogue flock of ivory billed woodpeckers was responsible for the toppling of the Devil's Chair rock formation along the St. Croix River earlier this month. (see this link for details).
