When a bird hovers, it is flying, but not moving through the air; when a bird windhovers, it is flying through the air, but it is flying upwind at the same speed as the wind. ... Strictly, windhovering is not hovering, but it is an interesting tactic used by some birds to temporarily hang over one spot.

The main reason owls can fly silently is the uniquely designed leading edges of their primary feathers. When most birds fly, turbulence — created when air gushes over the surface of their wings — causes noise. Owls' wings, however, are unique because they reduce noise caused by turbulence.

Can Birds Fly Backwards? ... The majority of birds are unable to fly backwards because of the structure of their wings. They have strong muscles to pull the wing down but much weaker muscles to pull the wings back up so the air around the wing is forced backwards pushing the bird forward.

Birds generate lift through the motion of their wings (they are also fairly light for their volume, which helps a lot). Fish (most of them, anyhow) have a gas bladder that controls their buoyancy.

If a bird poops on you or anything you own, it's said to be good luck. ... With as many birds as there are in the sky, it's supposedly more rare to be pooped on by one than it is to win the lottery. This actually prompts many people to play the lotto when they do get pooped on by a winged wayfarer.

A big part of the reason birds are able to fly is because their wings create airfoils that can split the air. We also find airfoils in the shape of tiny wings on bugs or huge wings on airplanes. However, human arms are not good shapes for airfoils. As you've observed, even if you try to flap, you won't fly.

A bird has wings which helps it to fly. Bird's wings have feathers and strong muscles attached to them. With the help of their strong arm and chest muscles, birds flap their wings and fly. The bodies of birds are very light which help them to fly easily.

Why Flamingos Stand on One Leg. Flamingos at rest, standing on one leg. This posture may be used by the birds to conserve body heat. The brilliant pink feathers, gangly neck and upside-down eating are enough to make flamingos a spectacle at any zoo and generate a barrage of questions from curious children.

Birds don't always have to flap their wings to fly. Once they're up high in the sky, they can also glide, which is kind of like getting a free ride on the air. They only have to flap their wings once in a while. They can also let a jet of air push them up even higher, to the tops of really tall trees.

Currently, all the cawing ravens which guard the tower except one, Poppy, have their wings clipped. This is when the flying feathers are cut back so the flight of birds is hugely limited.

Anyone watching the autumn sky knows that migrating birds fly in a V formation, but scientists have long debated why. A new study of ibises finds that these big-winged birds carefully position their wingtips and sync their flapping, presumably to catch the preceding bird's updraft—and save energy during flight.

A bird has wings which helps it to fly. ... With the help of their strong arm and chest muscles, birds flap their wings and fly. The bodies of birds are very light which help them to fly easily. This is because the bones of birds are thin, light and hollow.

Skimming permits the birds to take advantage of an aerodynamic phenomenon known as "ground effect." The patterns of airflow around a wing that is operating close to a surface are modified by that surface in a manner that reduces drag, the resistance of the air to the progress of the wing.

birds like ibises fly in a V formation by drafting off each other, the seventh paragraph begins by stating, “scientists do not know how the birds find that aerodynamic sweet spot.” In context, the phrase “aerodynamic sweet spot” characterizes the particular spatial relationship among birds in the formation that affords ...

Scientists have determined that the V-shaped formation that geese use when migrating serves two important purposes: First, it conserves their energy. Each bird flies slightly above the bird in front of him, resulting in a reduction of wind resistance.

Birds use songs to attract mates, defend territories, and to warn of dangers. They are triggered to start singing in the morning by the first light from the sun and at night sunset gives them the cues they need to stop singing.

Just like a seat-belt buzzer, the call is designed to get attention, and fast. During the winter, birds often sing fewer notes, or just one note, to each other. These notes are simply a way to alert the flock of their whereabouts and to announce whether there's any food nearby, Buhl said.
