Abstract

The database contains information on brain size, body mass, life-history traits and development mode for a total of 620 bird species. The taxonomy follows Jetz et. al. (2012). For life-history the database includes information for the following six variables: clutch size, egg size, incubation period, fledging age, maximum longevity; as well as development mode (altricial, semialtricial, precocial and semiprecocial). Additionally, in most cases there is information about the origin or the sampled specimen (captivity vs wild origin), quality control, and a nominal estimate of the sample size, all referring to the maximum longevity data.
