Full dataset of habitat, diet, and foraging behaviour traits used for computation of specialization of Australian passerines.

Traits for 308 species of Australian passerines include type of habitat, diet, foraging method, foraging stratum, and foraging substrate. Each trait is divided into several categories and each category of each trait has a value corresponding to proportional use (percentage) of that category by a given species based on information in HANZAB. The sum of all categories of a given trait for a given species is always 100.
