Jaw Musculature of the Mourning and White-winged Doves

A detailed anatomical investigation explores the jaw muscles of two familiar North American doves, seeking clues about their evolutionary ties. By dissecting a modest series of museum specimens and measuring dozens of skulls, the researcher compares the White‑winged dove with its mourning counterpart, documenting the subtle variations in bone shape and muscle attachment. The study places the findings within a broader context of avian feeding mechanics, noting how the gentle seed‑eating lifestyle shapes a comparatively modest musculature.

The paper describes a single, consistent muscle pattern across the examined species, highlighting the limited force required for their diet and nest‑building tasks. Through careful illustration and precise measurements, it offers a clear baseline for future comparisons and helps clarify whether the two genera—Zenaida and Zenaidura—share a closer ancestry than previously thought. Listeners will appreciate the blend of meticulous fieldwork and thoughtful analysis that brings the quiet world of dove anatomy to life.
