Seasonal breeding in humans: birth records of the Labrador Eskimo.
Moravian missionaries recorded all births in two Eskimo communities in northern Labrador from 1778 to 1940. These records demonstrate an annual cycle in births characterized by a peak in March, a trough in June, with an amplitude of 80%; they agree with previous observations on seasonal breeding among the Eskimo made by early Arctic explorers.
