Table A1. Data summary containing body mass (g), nest type, migratory behaviour, average clutch size (Clutch), estimated Kw for

genus and species, egg size (g), mean temperature during the warmest quarter (Bio10, Hijmans et al. 2005) as a proxy for mean

temperature during the breeding season (TempBreed), and annual range (max – min) of monthly actual evapotranspiration (Ahn

and Tateishi 1994) as a measure for actual evapotranspiration seasonality (AETseas) recorded for Fluvicolinae species across the

New World. Last column are listed the source references of egg measurements.

“MATERIALS AND METHODS” section. Number of estimable parameters (K), second-

include migratory behaviour (Migratory), nest type (Nest), species’ typical clutch size

Evapotranspiration seasonality (AETseas). We used log(Body mass) as covariate and

species as random factor in all models.
