Mexican biologists
Volcan de Colima, Jalisco, MX
January 26, 2001

John and Bill tagged along with biologists and students from the University of Guadalajara at Autlan, who were banding birds on the volcano at 10,000 feet. The rugged conditions (they camped) were made harsher by nightly temperatures below freezing, but the days were warm and there were lots of birds.
