How do hummingbirds manage to fly in such small spaces?

Hummingbirds, one of the world’s most agile and fastest birds, face the constant challenge of navigating tight environments in search of nectar. Surprisingly, these birds lost the ability to fold their wings close to their bodies, which led ornithologists to wonder how they were able to move efficiently in such small spaces.

Recently, a study was published in Journal of Experimental Biology It revealed the creative strategies these birds use to fly in tight spaces.

Aviation and experiment arena

The study focused on the purple-headed hummingbird, or Anna’s hummingbird (Anna Calipity), a species found along the west coast of the United States. The UC Berkeley team designed a two-sided flying apron to conduct the experiment.

Using alternating rewards, the researchers trained the young birds to fly across a specific gap in the arena. This controlled environment allowed detailed observation of the movements and strategies of hummingbirds as they encountered openings of different sizes.

The experiment revealed that hummingbirds use two distinct strategies to overcome openings in the arena. In the first, called “lateral,” birds approach the circular opening from the side, hover to assess size and then cross it, extending one wing forward and sweeping the second wing back.

In the second, or “bullet” strategy, they move the wings back, and quickly dash through the opening before pulling the wings forward. These strategies have been carefully analyzed using high-speed cameras and computer tracking.

Adapt and change tactics

The study also highlighted the remarkable adaptability of these small birds. Initially, it was observed that those who used the sideways strategy flew more cautiously, but as they became more familiar with the openings, they became more confident and chose to pass through them like a “bullet.”

This adaptation indicates a remarkable learning ability in hummingbirds. Even in the face of the smallest gaps, the birds adjusted their tactics to meet the challenge, showing remarkable flexibility in their flying abilities.

This study not only provides fascinating insights into the behavior of these birds, but also highlights their remarkable ability to adapt. The creative nature of hummingbird strategies leads us to appreciate the complexity and ingenuity of these charming birds. As research continues, new discoveries may emerge about the wonderful world of these beautiful little birds.
