Data from: Unpredictable Perturbation Reduces Breeding Propensity Regardless Of Pre-Laying Reproductive Readiness In A Partial Capital Breeder

The data file contains information on body mass at capture (BM1) or at release (BM2), the difference between BM1 and BM2 (DIFF) the concentration of VLDL and VTG, the YEAR (2003 or 2004),the Breeding Propensity with 1 indicating a breeding bird and 0 a bird non resighted in the colony, The Treatment category (maintained 24 hours in captivity or release immediately after banding), the release date in julian date and the band number (BAND)
