Cover from 'Extra-pair paternity correlates with genetic diversity, but not breeding density, in a Neotropical passerine, the black catbird' by LaPergola et al. The cover features an original watercolor of a black catbird by first author Josh LaPergola. Josh was motivated to take up watercolor in January 2021, a time when the raging SARS-COV-2 pandemic halted international travel, preventing fieldwork. The piece is based on a photograph taken by co-author Bob Curry during Josh's first trip to the Yucatán, when he was scouting for potential field sites and first getting to know the black catbird.
