Nest Cooling and Recess Length of Incubating Spruce Grouse

Grouse are relatively large-bodied single-sex incubators that spend approximately 5% of each 24-hr period away from the nest foraging. The authors monitored the incubation rhythm of female Spruce Grouse (Dendragapus canadensis ) in the wild to document the relationship between recess length and the...

Description
Summary:Grouse are relatively large-bodied single-sex incubators that spend approximately 5% of each 24-hr period away from the nest foraging. The authors monitored the incubation rhythm of female Spruce Grouse (Dendragapus canadensis ) in the wild to document the relationship between recess length and the cooling of exposed eggs (as measured by changes in nest-bottom temperature).
