What is a bird’s alula?
BirdsFlight
Quick Answer
The alula is a small group of feathers on a bird’s thumb that helps control airflow at low speeds. It acts a bit like a wing spoiler during takeoff and landing.
The Full Story
The alula is a tiny, thumb-like structure on the front edge of a bird’s wing, made of a few small feathers attached to the first digit. When a bird flies slowly, lands, or maneuvers tightly, the alula helps keep airflow attached to the wing and prevents stalls. It is important for birds that need precise low-speed control, such as hawks, pigeons, and many songbirds. This adaptation makes bird flight more stable and agile.
