Poultry Judging Practice Test

Chicken and turkeys are more sensitive to which portion of the light spectrum?

1. Blue

2. Green

3. Red

4. Ultraviolet

The correct answer is: Red

Chickens and turkeys are actually more sensitive to the ultraviolet portion of the light spectrum. This sensitivity plays a significant role in their behavior and social interactions, as many natural cues that influence their environment are in the ultraviolet range. Birds possess photoreceptors that allow them to see ultraviolet light, which is invisible to humans. This enhanced vision is important for various behaviors, such as foraging, as it helps them detect patterns and markings on plants and potential mates that are not visible to the human eye. While chickens and turkeys can perceive blue, green, and red light, their unique eyes and visual systems enable them to effectively utilize ultraviolet light to navigate their surroundings and communicate. Understanding this sensitivity is essential in poultry management and environmental design, as it can influence how light sources are used in poultry housing and can impact their well-being and productivity.
