Measurements of body mass, energy expenditure and feather corticosterone in captive Mallard ducklings

This data set contains morphometric (body mass, feather size) and physiologic (daily energy expenditure, feather corticosterone) measurements obtained from female mallard ducklings, collected in a captive experimental setting. Four spreadsheets are contained within the .xlsx file, including: Legend - describes each of the variables; Treatments - body mass, duckling age and experimental treatment over all phases of the experiment; DEE - daily energy expenditure obtained from doubly labeled water; and Feathers - measures of feather corticosterone and feather size for both phase one and phase two
