How can geese fly

Birds use less energy flying in a V formation. By doing so the birds work together and are more efficient. Being more efficient and using less energy allows them to stay in the air longer and fly longer distances. Expending less energy allows geese to fly longer distances because the geese can save more energy. As a result, the geese gets less tired and flies great distances. It seems interesting because when I was a kid, I seemed interested why the birds made a "V" shape.

What shocked me is that, I didn't think that the "V" shape is efficient because it would save more energy. Expending less energy allow geese to fly longer distances because flying takes a lot of energy like flapping their wings. I think that it is intelligent and fascinating that the birds have a sort of system of flying. They all have an eye on one another and have techniques to fly longer distances.

Not from cars, but geese migrating somewhere warmer. I saw two separate flocks merge and eventually reform into a bigger V. Are they trying to spell "Vancouver" or is something else going on with their V formations?

The common explanation seems to be that the arrangement enhances lift and reduces drag so flying together burns less energy than going alone. This would a good thing since Canada geese can fly for sixteen hours without stopping. To reduce drag and to receive a little extra lift, geese fly close behind and about one wing length to the side of the one immediately in front.

When all flock members do this, the familiar V shape appears. This form of drafting, also called vortex surfing , saves a lot of energy. Following another bird at the right distance blocks any headwind. The flapping of the bird ahead creates a forward movement of air called a slipstream, which helps pull the trailing bird forward.

And little pockets of spinning air, called vortices, produce lift that helps keep a trailing bird aloft. The same physics explains why fighter jets fly in V formation to conserve fuel. The bird at the point of the V, in the front of the flock, gets no advantage from drafting.

It is working much harder than the others. When it gets too tired, it drops back and another takes the lead. Recently, ornithologists have discovered that when families migrate together as a flock, the parents take turns at the tip of the V. The younger geese, which are not as strong, line up along the V behind the lead parent. Most geese that breed in a particular region will migrate along similar routes, called flyways.

For example, geese that pass by my house in Northern New York follow the Atlantic flyway. Contact us: communications billgosling.

Geese Fly Further Together The iconic flying V is for more than just allowing the geese to see something other than the back of the bird in front of them. Geese Support Each Other When Times are Tough When a goose gets injured or sick, two other geese will fall out of formation to stay with the goose and stay with it until it is able to fly again.

Geese Take Turns Leading Due to the lift created in the V formation, there is no one creating any lift for the front goose. Geese Cheer Progress Geese can be heard honking loudly while they fly.
