From Nest to Sky: How Birds Learn to Fly
One of nature's captivating spectacles is witnessing the development of animals, particularly nesting birds and their fledglings. The journey of a bird from a helpless hatchling to a soaring creature is a testament to the power of instinct, practice, and parental guidance. While we often admire the grace and ease with which birds navigate the skies, it's easy to overlook the complex process that enables them to take flight. No bird is born knowing how to soar, nor does it know when is the right time to leave the nest.
The Fledgling Stage: A Time of Transition
Growing up is dangerous. In the natural world, times of transition are the most perilous. This is especially true for offspring, who easily fall prey to predators while they are still finding their footing. Parent birds know this, which is why their goal is to get their nest empty as soon as possible. Fledglings are young birds that are in the process of learning to fly. They usually begin trying to fly when they are about two weeks old. At such a young age, the fledglings are motivated by one thing: a need to feed.
Fledglings usually begin trying to fly when the birds are about two weeks old, and although they have started to leave the nest, they are not on their own, according to the Massachusetts Audubon Society. Some birds leave their nests before they can fly, while others, mainly cavity nesters like woodpeckers, stay put until they master the necessary skill, the Cornell Lab of Ornithology reports. Leaving before they can fly is a means of survival.
The Role of Instinct and Practice

Oftentimes, learning to fly means falling from the nest and making the long trip back to it. Eventually, the fledglings - young birds learning to fly - come to realize that falling from the nest is a bit easier if they spread their wings. But even then, it isn't with the grace with which we are accustomed to seeing birds fly. They still have to practice to learn how to take off and land and discover how the wind affects flight, Wise Geek reports.
Learning to fly is not an innate ability; it requires practice and refinement. Fledglings must learn to coordinate their movements and develop the strength and stamina necessary for sustained flight.

Parental Guidance and Encouragement
Parent birds play a vital role in teaching their young how to fly. They bring them food, which they quickly learn is necessary for their survival. Each time the parent returns to the nest with nourishment, they position themselves a little further away. In order to reach the food, the fledglings must eventually leave the nest. At first, they fall every time-until they discover that they can brace their descent by spreading their wings. At such a young age, the fledglings are motivated by one thing: a need to feed. Their parents bring them food, which they quickly learn is necessary for their survival. Each time the parent returns to the nest with nourishment, they position themselves a little further away. In order to reach the food, the fledglings must eventually leave the nest.
Overcoming Challenges and Building Confidence
Birds don’t leap into the air out of some innate sense of purpose or faith that the wind will carry them. They don’t even do it out of an evolutionary urge to take to the sky. They learn to fly by following the path laid out in front of them, by chasing what nourishes them. It’s a process that involves trial by error, falling face first to the ground, and a willingness to get up again.
Fledglings on the Ground: What to Do
All birds learn to fly from the ground and not from the nest. For this reason, the young birds come out of the nest and down to the ground. You will see them hopping around and extending their wings while their parents continue to feed them. These baby birds are typically fully feathered and alert, holding both wings to the body, which is why the term “fledgling” describes them at this stage in their lives. If you see a bird on the ground with Downy feathers on its head, don’t be alarmed; the bird is most likely a healthy fledgling.
If you find a baby bird on the ground, it may very well be a fledgling that's still learning its way in the world. Hatchlings and nestlings are baby birds that can't walk, flit or fly, and they usually have few or no feathers. If the bird is injured, or you can be certain it was orphaned, the best course of action is to take it to a wildlife rehabilitation center.
Most songbirds leave the nest before learning to fly. They are usually fully-feathered but may appear to have a shorter tail. Siblings may wander about, scattering in different directions while the parents continue to find, follow and care for them. This stage can last for several hours to a day or so, and in the case of Great Horned Owls, weeks. People often find fledgling birds temporarily stranded in a yard or on a porch and think they need help. This is a very important transition time for these birds and should not be interrupted. Birds brought into rehab during this time have a poor chance of survival. They are old enough to know that people are not their parents and resist being hand fed, yet they haven’t learned to feed themselves. If uninjured, stranded fledglings can be moved to a safer location nearby.

Most importantly, when you see a healthy bird, do not disturb it. This phenomenon is all part of Mother Nature’s process. Human hands can cause parents to stop providing food and education to their young children. We do not want to hamper these birds’ learning to sing, fend for themselves, ward off predators, and migrate, as it is all part of the circle of life.
Please remember to keep your pets away from the area at this stage of the baby bird’s development. The less we intervene, the better. Let nature take its course.
Nesting Birds: Tips for Coexistence
As I watch a pair of birds building a nest under our eaves in our decorative hanging basket adorned with potted fuchsia, I am reminded that during the spring season, we must take precautions for nesting birds and fledgling birds that may be lurking in our backyards.One of nature’s beauties is watching the birth and growth of animals. This is true of nesting birds and the fledgling birds that hatch from their eggs. Both parents participate, as the mother goes searching for food and the father watches over.
Here are some helpful hints to keep in mind if you see birds building or perched in a nest. First, it is a good idea to avoid trimming trees or bushes in the area of the nest. Actually, it is better to prune trees when they are dormant, which is usually from November through January.
Do not disturb or destroy a nest because it stresses adult birds, who often abandon the site. If this happens while the chicks are still in the nest, they will likely starve.

If you accidentally disturb a nest, leave the vicinity immediately so the parents can get back to it quickly. The longer the adult birds are away from the nest, the more vulnerable their young become.
Try to stay away from the area while the birds are nesting. If a nest is exposed, it should be recovered so it appears undisturbed to the birds and is protected.
The Power of Community
Birds don’t go through this process alone, though. Species that fly in V formations do so out of an ingenious display of evolutionary aerodynamics-and community. As a bird flaps its wings, it creates an upwash behind and to the sides of it. Other birds in the flock fly in these upwash zones, allowing them to save energy. The further back the birds are in the formation, the slower their heart rates and the fewer times they have to flap their wings. They take turns who is leading, falling to the back when they need to conserve energy, which allows them to fly for longer periods of time. Birds have quite a bit to teach us about organizing, too. Have you ever wondered how a murmuration of starlings moves with such synchronization? While hundreds to even thousands of these creatures might fly together at once, they stay in unison by focusing their attention only on the movement of the seven starlings that surround them. This has somewhat of a ripple effect, resulting in the murmuration moving as one.
