No animal can have guided flight without wings. The closest there is to true flight without wings are spiderlings, which have no control of direction, like a hot air.
Spiderlings (baby Spiders) are able to fly using very fine silk called gossamer. They will let a long strand of this silk out and they use it to ride the wind, similar to a kite or hot air balloon. In fact, it is often called 'ballooning' or 'kiting'. Spiderlings use this method to disperse so they will not compete for food with their parents or siblings. Spiderlings have been found on atmospheric data balloons nearly as high as 5 km (3.1 miles), and in the sails of ships more than 1600 km (1,000 miles) from shore.
Some animals which appear to fly without wings actually don't fly but they glide e.g. flying lemur of Philippines and the various gliders of Australia, members of the possum family. Like the so-called flying squirrel, they have skin membranes which stretch from their wrists to their ankles. They can only glide from trees and high places to safety below: this is safe for them as the skin acts as a parachute with air resistance. There are also some reptiles, amphibians, fish and insects capable of gliding without true wings.
For a list of these other gliding creatures, see the discussion page.
there is no such thing there is no bird that is not a bird even if it doesn't act like a bird
Birds have feathers, which serve multiple functions such as insulation, waterproofing, and aiding in flight. Feathers are a unique feature of birds that help them to maintain body temperature, display colorful patterns during courtship, and enable them to fly.
No. Some exceptions are bats, mosquitos, flies, bees, ladybugs, locus, June beetles.
No, most animals are insects and have shells. Only birds have feathers.
Yes. Some types of birds (like ducks) moult all their feathers at once and so have a period when they cannot fly. Other change one or more feathers at a time and can always fly.
so they can fly and live in the sky

"Byrd" is a variant of "Bird." It means, just that, the animals that have feathers and most of which fly.

Ostriches have down feathers. Because they can not fly they have no need for contour feathers...
Birds cannot fly at all without their feathers.
Most animals have feathers or scales. Some have a shell like a turtle or a snail. Reptiles have scales such as lizards. And birds have hollow feathers that help them fly.
There are no animals that have feathers besides birds.
the tail has flight feathers and the flight feathers help a bird to fly.
