Description
These data are from a study evaluating Allen's rule, which is the proposition
that warm-blooded animals have shorter extremities in colder climates to aid
in heat retention. In this study, the authors evaluated this proposition across
bird species for bill and tarsus (leg) length.
Usage

Format
A data frame (tibble) with 215 rows and 9 variables:
