They nest among rocks and cliffs. The nests are made up of shells and debris or of dead vegetation. Clutch size is 3, on average, and the chicks hatch in 3 to 4 weeks. Young fledge in 27 to 30 days. Common tern chicks are able to fly by the time they are a month old but do not reach sexual maturity for 3 years.ommon terns are found from northern Canada south to the Caribbean Sea, as well as throughout Europe, Northern Asia, North Africa, and the Middle East. Some populations of common terns winter in the south to Peru and Argentina. (Ehrlich, et al., 1988; Malling Olsen and Larsson, 1995).
Queens of eastern subterranean termites, the most common species of termites found in the United States, can live up to a staggering 30 years, but a 15- to 17-year life span is more common. For some African species of termites, a queenâs life span may be up to 50 years, while in other species, such as drywood termites, the queens live only 10 to 12 years. In general, worker termites live about two years. No matter what type they are or what point in the termite life cycle, termites are trouble.
