I'm happy to announce the birth of my three new Columbian red tail boas! The mother, Delilah is 7' and dad, Stanley, is 6'. After mating in the fall, the female stops eating. Gestation lasts for 4 to 10 months, depending on temperature and humidity. Unlike many other snakes, Columbian red tail boas give birth to live young, usually 10-60 babies. Newborns are 12"-18" long, and will increase in size by up to 300% in their first year, reaching 5-8 feet. This species is particularly friendly and, if handled often, makes a great pet.
