- Title
Avian lower beak is always overlooked: its coordinate role in shaping species‐specific beak should not be underestimated.

- Abstract
The article discusses the importance of the lower beak in avian species and its role in shaping the overall beak morphology. While the upper beak has traditionally received more attention in research, the lower beak plays a critical role in feeding and may coordinate the shape of the upper beak. The article explores the anatomical and developmental differences between the upper and lower beaks and suggests that bone resorption in the lower beak may affect the shape of the upper beak. Further research is needed to investigate the relationship between the length of the lower beak and the shape of the upper beak, as well as the genetic and developmental factors involved.
