Data from: Smaller distance between nest contents and cavity entrance increases risk of ectoparasitism in cavity-nesting birds

Dataset used in Tomás et al. (2020): (DOI: 10.1111/jav.02427). Data were collected in the Hoya de Guadix in 2012 in spotless starling (Sturnus unicolor) nests in the framework of an experiment to evaluate whether distance to the cavity entrance and nest size influence the risk of ectoparasitism in avian nests. Dataset includes hatching date, brood size, mean nestling body mass, microclimate of the cavity, as well as ectoparasite abundance and distance between the nest and the cavity entrance before and after experimental manipulation.
