White-throated sparrow survivorship data

This file contains the datasets used to examine rates of actuarial senescence in the four morph-sex classes of the white-throated sparrow (Zonotrichia albicollis) in R package BaSTA. Three files total are required: (1) A birth-death year file, containing the birth and death years (unknown entered as 0) for all individuals included in the data set, (2) A survival file, with a line entered for each year in which an individual was re-sighted, (3) A covariate matrix, listing the sex and morph of each individual. This is the survivorship data.
