Birds' seasonal biology involves deep light sensing
Updated
Abstract
The avian hypothalamus directly senses light, which influences endocrine physiology in response to seasonal day-length changes.
- Photoreception in the avian hypothalamus is linked to seasonal changes in day length.
- The photopigment VA-opsin is associated with this light-sensing mechanism in birds.
- This process may help synchronize physiological responses to environmental light conditions.
