Human Factors
While completing a training flight with a student over the Hudson River; about a mile south of the Verrazano Bridge; we nearly collided with the pilot(s) of a Cessna 172 who were not communicating on the CTAF. A third party yelled at us on the CTAF to advise us that a Cessna was straight ahead at the same altitude; opposite direction. Seconds later I saw the aircraft and took control from my student; executing an evasive right turn. I'm estimating that we were just over 400 ft. laterally from the other aircraft; at the same altitude.
SR22 Instructor Pilot reported an NMAC with another aircraft not on CTAF.
