This file contains the data for the analyses of nesting mass, change in mass between nesting and banding, and ninth primary length. Note the some nesting mass (nmass) data is blank when the change in mass variable (chng_mass) is not, this is because in this case the female did not undergo a clutch manipulation and therefore was not used in the nest mass analysis. The variables are as follows: "METAL" is the unique code on the female's steel band, "emcs" is the final manipulated clutch size a female incubated,"gln" is the initial brood size of the female, "nmass" is the mass (g) of the female if she was captured within 24 hrs of hatch and underwent a clutch manipulation, "YEAR" references breeding season t, "NINTHPRIM" is the length of a female's ninth primary feather on the day she was captured during brood rearing,"DSH" is the days between when a female's nest hatched and she was captured during brood rearing,"chng_mass" is the change in the mass of a female between hatch and when she was captured during brood rearing.
