The nightingale was named due to the fact that it is often heard singing during the night as well as during the day.But, it usually stops singing when its eggs are hatched, to avoid attracting unnecessary attention on its nest. However, it does give little chirps to keep his female counterpart aware of their safety or any approaching danger.

A duck has water-proof feathers. There is a special gland called the 'Preen Gland' or 'Uropygial Gland' near the ducks tail. This tiny gland produces oil which the duck uses to coat its feathers.
The duck picks up the oil with its head and beak, and then smears it all over its body to make the outer feathers waterproof. Without this protective barrier, a ducks feathers would become water-logged and because they spend their whole lives around and in water, this water-proof barrier is extremely important.
Beneath the water-proof coat are fluffy and soft feathers which keep the duck warm.If you were to dip or pour a degreaser on the duck, it would remove the oil and the duck would drown in water.
Because the feathers are waterproof, they can trap air and this also helps to keep the duck afloat. When the duck dives under for food, the air is squeezed from the feathers. Also, the duck has air sacs (lungs) that it empties before diving. When it has caught the fish or whatever it is after, it kicks back to the surface. As it's head breaks the surface, it takes a deep breath and as the lungs fill up, it is jerked to the surface. A quick ruffle of the feathers and it is back to normal, floating on the surface.
┗▶ Also They are comfortable walking on ice because their feet have no nerves or blood vessels making the duck unable to feel cold.

★ The rapid beating of the hummingbirds wings (60 to 80 beats per second) makes the distinctive humming sound from which they get their name.
★ Inspite of being the lightest bird on planet (0.2 oz.) it is also the only bird capable of flying backwards
★ The hummingbird is also the smallest bird and also the smallest of all animals that have a backbone.
★ Hummingbirds are the second largest family of birds with 343 species.
★ A hummingbird has no sense of smell
★ Because the hummingbird can rotate its wings in a circle, they are the only bird that can fly forwards, backwards, up, down ,sideways and hover in mid air.
★ The normal resting heartbeat of a hummingbird is 480 beats per minute, this number can go up to 1,260 per minute when it is excited.To conserve energy while they sleep or when food is scarce, they can go into a hibernation-like state (torpor) where their metabolic rate is slowed to !/15th of its normal rate.
★ Hummingbirds cannot walk or hop, though their feet can be used to scoot sideways while they are perched.
★ Hummingbirds have 1,000-1,500 feathers, the fewest number of feathers of any bird species in the world.
★ Hummingbirds can beat their wings up to 80 times a second during normal flight and up to 200 times per second during a courtship dive.
★ Hummingbirds can flash their bright colors, as well as hide them when needed.This allows hummingbirds to flash colors or hide them which is useful for males who want to impress females or threaten other males.
★ The bright radiant color on hummingbirds comes from iridescent coloring like on a soap bubble or prism
★ An average hummingbird’s heart rate is more than 1,200 beats per minute.
★ At rest, a hummingbird takes an average of 250 breaths per minute.
★ The rufous hummingbird has the longest migration of any hummingbird species with a distance of more than 3,000 miles from the bird’s nesting grounds in Alaska and Canada to its winter habitat in Mexico.
A hummingbird's brain is 4.2% of its body weight, the largest proportion in the bird kingdom.

★ Penguins are birds that cannot fly.
★ They are great swimmers and divers.
★ The torpedo shape of their body helps them swim at high speeds.
★ Their feathers are waterproof and help them maintain insulation. A gland near the penguin's tail secretes oil into its feathers, which the bird will spread thoroughly while preening its feathers to provide waterproofing.
★ Their eyes work better underwater. This helps them in spotting prey while swimming.
★ Penguins can live for 15 to 20 years.
★ They vary in height from 16 inches to about 4 feet.
★ Parents take turns warming the egg, male penguins take care of their chicks and female penguins go for searching foods.
★ They take small naps in the water.
★ Penguins use sign language to communicate with each other. They make use of their flippers and head to talk to other penguins.

★ Butterflies are typically diurnal (active in the daytime), but Owl Butterflies are crepuscular (most active at twilight).
★ On the hind wings of an Owl butterfly are large "eye-spots" which look like an owl's face.
★ Its staring, owl-like hindwing "eyes" can help deter any predators that do spot it are used to scare away predators.
