Corvids, Weighed

Ten crows, ravens, magpies and jays on one scale, by published species-average body mass.

A common raven outweighs ten blue jays, yet most pictures draw every corvid the same size. This chart puts ten of them, from Europe and North America, on one scale, from the raven down to the Canada jay.

Every figure comes from AVONET, a peer-reviewed database of bird measurements (Tobias et al. 2022, Ecology Letters), and the full citation is printed along the foot of the chart.
