Cool Facts
The Eastern Towhee and the very similar Spotted Towhee of western North America used to be considered the same species, the Rufous-sided Towhee. The two forms still occur together in the Great Plains, where they sometimes interbreed. This is a common evolutionary pattern in North American birds – a holdover from when the great ice sheets split the continent down the middle, isolating birds into eastern and western populations that eventually became new species.
