Data Repository for raw data of great tit nest temperatures recorded on Vlieland, the Netherlands, from 2020-2022

Dataset of the nest temperature, ambient temperature and light intensity data recorded for the PhD project of Aurelia F. T. Strauß. The data is used for two projects:1. observational study linking diel timing, fitness and life history:"Female chronotype relates to lay date but not fitness in wild great tits" from Aurelia F. T. Strauß, Barbara M. Tomotani, Barbara Helm and Marcel E. Visser submitted to <i>Oecologia</i>2. experimental study (light treatments inside the nest-box) conducted in spring 2021"Short-time exposure to light at night affects incubation patterns and correlates with subsequent body weight in great tits (Parus major)" from Aurelia F. T. Strauß, Lies Bosma, Marcel E. Visser and Barbara Helm published in <i>Journal of Experimental Zoology Part A</i>.
