Surakav belongs to the family Humming Birds. This bird is the only North American hummingbird with a red head. The colour of the feathers changes according to the movement of its head. Different colours appear on the bird through the movement of the head in a way that amazes the viewer.
Juvenile hummingbirds, however, do change color as they shed the plumage they are born with. They then begin to show the bright colors of their parents. As the young mature and move about, the light reflects off their plumage, appearing to change colors.
The Surakav Bird or male Anna’s Hummingbird is one of the most popularly searched birds on the internet. And the reason is obvious. Its amazing features makes it more interesting than the rest. Internationally, the bird is sold for a whopping Rs.
Some very large birds may molt some feathers at longer intervals, but most adult birds undergo a complete molt at least once annually. Ad- ditional molts, often partial, occur in many birds. It is by the loss and replacement that birds effect color changes of feathers if they change colors at all.
The chukar (Alectoris chukar) is the official national bird of Pakistan, and the shaheen falcon is the symbolic icon of the Pakistan Air Force and Pakistan Avicultural Foundation, one bird is endemic.
Chameleons can stretch their iridophores to change the wavelength—and therefore the color—of the light they reflect. The reflected light from iridophores works in concert with the pigment in the chromatophores to produce the suite of brilliant blues, reds, and oranges seen in many chameleons.
American Goldfinch (above)
The American Goldfinch undergoes such a radical transformation between seasons, it’s hard to believe that the gray-green birds of winter and the yellow-and-black birds of summer belong to the same species.
Anna’s Hummingbirds are mostly green and gray, without any rufous or orange marks on the body. The male’s head and throat are covered in iridescent reddish-pink feathers that can look dull brown or gray without direct sunlight.
A hummingbird’s brilliant throat feathers are called its “gorget” (pronounced gor-jit). The term comes from days of old, when a knight-in-armor wore a metallic collar—or gorget—to protect his throat. The hummingbird’s intense glint is the result of iridescence, rather than colored pigments.
Although blue jays are widely recognized by their bright blue colour, they are (surprisingly) not actually blue. Their bright blue plumage is the result of a unique inner wing structure that distorts the way light is reflected; making them appear blue.
Toucan. The toucan bird is perhaps one of the most recognizable due to its colorful and very large bill.
This article showcases 10 of the most colourful birds. Scarlet Macaw. Toco Toucan. Mandarin Duck. Stork-Billed Kingfisher.
Male House Sparrows are brightly colored birds with gray heads, white cheeks, a black bib, and rufous neck – although in cities you may see some that are dull and grubby. Females are a plain buffy-brown overall with dingy gray-brown underparts.
The Markhor (Capra Falconeri) is the largest of the goat family and is commonly found in the Northern Areas of Pakistan. The name Markhor translates to “snake eater” in Persian, for the Markhor holds great skill at killing snakes in the wild to protect its harem.
The change of skin color helps them to adapt to their surrounding. Mimic octopuses can change color and mimic shapes due to their skin which is very responsive to the environment.
When most people think of colour change, they think of octopuses or chameleons - but the ability to rapidly change colour is surprisingly widespread. Many species of crustaceans, insects, cephalopods (squid, cuttlefish, octopuses and their relatives), frogs, lizards and fish can change colour.
Ants, Termites, Bees and Beetles
Ants, bees and beetles go through the same metamorphosis stages as butterflies. However, the metamorphosis of termites is considered an incomplete process, because the animals do not go through the chrysalis stage. This is called hemimetabolism.
Most of the dramatic seasonal changes in a bird’s appearance are the result of molt — that is, the replacement of old feathers with new. A male Scarlet Tanager replaces the drab greenish feathers of winter with intense red in spring, and then molts back to greenish in the fall.
All birds do it; they have to grow new feathers once or twice a year to stay warm, dry, and airborne, and in many cases they grow differently colored feathers at different seasons to match their surroundings or to impress others of their species.
Unlike many white animals associated with the north, such as polar bears and snowy owls, which are white all year, these creatures shift their colors with the seasons.
Ruby-throated Hummingbirds are bright emerald or golden-green on the back and crown, with gray-white underparts. Males have a brilliant iridescent red throat that looks dark when it’s not in good light.
The male Anna’s hummingbird has a striking reddish-pink crown and gorget, which are strongly iridescent and dependent on the angle of illumination and observation by female or male competitor birds.
But if light enters at an angle, it will have to travel a greater distance to pass through the cube. The changing angles alter the red color that is reflected back. So, when a hummingbird turns its head, the gorget seems to change from one shade of red to another in a shimmering fashion.
Meet the rufous hummingbird, a tiny roughneck that casually chases away other hummingbirds, even while migrating. These little guys are bright, even glowing in the right light.
Blue jays are usually regarded as bearers of good news, fortune, and luck! It’s often believed that finding a feather of a bluejay means that someone in the house will receive money, great news, a nice letter, or a gift soon!
