Bank Myna Preening Behaviour

The Bank Myna uses its beak to rub its wings and other parts of its body as part of a grooming behavior known as preening, which is essential for its feather maintenance and overall health. By preening, the Bank Myna removes dust, dirt, and parasites that may have settled on its feathers, keeping them clean and functional. This process also involves realigning feathers, which is crucial for maintaining insulation and streamlining their shape for efficient flight. Furthermore, the bird uses its beak to spread an oily substance from a gland located near its tail, called the uropygial or preen gland. This oil coats and protects the feathers, making them water-resistant and flexible. Altogether, preening not only ensures that the Bank Myna’s feathers remain in optimal condition but also plays an important role in regulating body temperature and preserving the bird's health.
