10/4-5/16, 8:00 PM-6:30 AM -- Yard, Westport CT While looking over recordings from this night, I came across two calls that appeared to me significantly higher and purer-toned than standard gray-cheeked calls. Both peak at around 5 kHz. The call at 2.55.46 is the highest of the two, and thus more likely Bicknell's. Am I correct in calling them BITH? Thank you for any assistance.
