Abstract
Methods
We quantified nest building contributions and several life history and ecological traits for 521 bird species. Nest building contributions were classified by coding the species’ descriptions in the Birds of the Western Palearctic book series and were classified as being ‘neither’ if no birds collected materials, ‘male’ if males build the nest alone, ‘female’ if females build the nest alone and ‘both’ if males and females build the nest together. Nest sites were classified as being grass/reed, ground, ground hole/cavity, ledge, tree/bush, tree hole/cavity, wall or water. Nest complexity/structure was classified following the approach of Hall et al. (2013), although we added an extra ‘dome’ category to separate the domed nests from the cup nests of species. We defined clutch sizes as the means of the upper and lower average values of the published clutch sizes. The sex that incubates was defined as being ‘male’, ‘female’ or ‘both’. The duration of breeding was classified as the number of months between the first and last month of breeding. We used the mean average of the maximum and minimum breeding ranges for measuring species' mean breeding latitude values.
