Monthly temperature regimes for four populations of nesting Golden Eagles as related to the thermoregulatory critical period for nestlings. Bars give monthly high and low averages for 1972. The cross line is the normal monthly average temperature. The shaded bars indicate the critical period for nestling eagles (3 to 6 weeks of age).
