What to know about Songbirds may have developed sharper senses to de-husk seeds

Researchers from several universities studied the brains of 92 songbird species to determine how seed-dehusking abilities evolve. The study found that birds capable of removing seed husks have enlarged sensory brainstem nuclei related to touch in the tongue, rather than larger motor nuclei.

Why it matters

Yet some songbird species also have another remarkable skill: They can easily remove the tough layer covering seeds (i.e., the husk) before swallowing their nutritious interiors.

Common ground

Researchers at the University of Alberta, the University of Lethbridge and the Catholic University of Chile recently compared the brains of 92 different songbird species to uncover changes in the brain that may be linked to the emergence of seed-dehusking…
