What does preening describe in bird behavior?

Preening is an essential behavior observed in birds, and it primarily involves cleaning and arranging their feathers. This activity helps to maintain feather condition, which is crucial for insulation, waterproofing, and aerodynamic efficiency. Birds utilize their beaks to remove dirt and debris from their feathers and to realign them, ensuring that they lay flat against the body for optimal flight and insulation.

Moreover, preening also allows birds to spread vital oils from a gland located near their tails, which helps waterproof their feathers and maintain their health. This behavior contributes significantly to a bird’s overall maintenance and well-being, making it a critical aspect of avian biology. Therefore, understanding preening is fundamental for anyone studying bird behavior and falconry, as it reflects the health and care of the bird.
