Abstract: Lay Summary Seasonal organisms use temperature as a cue in reproductive decisions, but the role of climate change is not yet clear. Here, an experimental increase in temperature during laying in a small passerine bird reveals that heated females adjusted their incubation behavior and the number of eggs laid, and produced nestlings of equal condition over the season, unlike control females. A small temperature increase may therefore influence breeding strategy and offspring phenotype.
