Linear mixed models with “NestID” as random factor were used to avoid pseudoreplication. Top ranked models included noise in combination with sex (s), light, brood size (b), laying date (ld), fledging mass, the interaction light:sex (light:s) and/or the interaction noise:light. Fledging mass models were run on data from 562 nestlings from 85 nests; Hp models on data from 475 nestlings from 78 nests and NOx models on data from 344 nestlings from 58 nests. Only models within ∆ AICc < 2 of the top model are shown.
