ReadMe for E. F. Purves, M. A. Conboy, R. J. Robertson, and P. R. Martin. 2015. Data from: Does white tail patch size indicate quality in male Cerulean Warblers (Setophaga cerulea)? Wilson Journal of Ornithology. This readme file describes the variables in the four data files (Purves_main data, Purves_24 male subset, Purves_museum data, and Purves_parasitemia data) in the above manuscript. R code for the main analyses are included as a supplementary file as well.
