Winter and Breeding-Season Energetics of Nonmigratory White-Crowned Sparrows

The lives of most temperate-latitude birds are organized on an annual cycle that includes reproduction, molt, dispersal, and/or migration. Weathers et al used the doubly labeled water technique to examine seasonal variation in field metabolic rate of a resident coastal population of White-crowned Sp...

Description
Summary:	The lives of most temperate-latitude birds are organized on an annual cycle that includes reproduction, molt, dispersal, and/or migration. Weathers et al used the doubly labeled water technique to examine seasonal variation in field metabolic rate of a resident coastal population of White-crowned Sparrow located at the southern end of Point Reyes National Seashore in California.
