When Is a Bird a ‘Birb’? An Extremely Important Guide

Oct 25,  · Fishes, reptiles, and mammals are also vertebrates; however, birds are unique in having the following features: Birds have feathers, which are modifications of the outer skin. Birds are the only vertebrate with feathers. The ability to fly is perhaps the most common attribute of birds. Birds are the only living creatures with feathers. Feathers are made of keratin, the same protein that makes up bird beaks, lizard scales, mammal hair, human ?ngernails, and animal hooves and horns! Feathers help birds ?y and keep them warm and dry.

Birds were able to become flying machines largely through the evolutionary gifts of feathers, powerful wings, hollow bones, warm blood, a remarkable respiratory system, and a large, strong heart. These adaptations all boil down to the two prime requirements for any flying machine: high power and low weight.

Bird have descended from bipedal, reptilian-like dinosaurs that lived in the Jurassic period approximately millions years ago and are scientifically classified as follows:. Members of whatever you like free mp3 download class Aves are placed into more than 2 dozen orderssuch as the Passeriformes perching birds.

The orders are divided biird approximately families which can be recognized by the ending of "idae" such as Turd idaethe Thrush family, which includes robins, thrushes, and bluebirds. The next 2 groups, genus and species are combined to give the bird's scientific name. No other creature in the animal world may share that combination of names. Each genus is made up of the x considered most closely related; all members of a genus are descended from a shared ancestral bitd.

The name of the genus is capitalized, the name of the species is not, and both are italicized. In order to meet the rigorous demands for air consumption that intense living, flight, and song impose on them, birds must have ample and efficient breathing machinery.

Not only is their respiratory system the most efficient known among all vertebrates, but it is unique in basic structure. Humans and other mammals breathe by means of a cul-de-sac respiratory system in which inhaled fresh air is mixed with residual stale air remaining in the dead-end alveoli of the lungs, which can never be completely emptied. Birds, on the contrary, have a complex weight-reducing system of air sacs and interconnecting tubes that make possible a more thorough bathing of the lung cells with fresh air.

This is a very unique bird characteristic. To help supply heavy oxygen demands, the lungs are supplemented by a series of air sacs that let the bird inhale more air make the lungs can hold at one time. These air sacs fill all the available spaces within the body cavity and also contribute to the bird's lightness. Soaring species have air sacs extending to their hollow bones, others have a series of small s sacs paralleling the trachea. Some diving birds use whah reserve air in the sacs while submerged, but deep divers have reduced air sacs to eliminate buoyancy.

Bird Vision Vision is the bird's kakes highly developed sense. Unlike most animals, they see q color. Birds can distinguish objects much farther away than can humans, and their vision is in fact the most highly developed of any animal. Birds have big eyes. Hawks, eagles, and owls often have eyes actually larger than human's. A unique bird characteristic. The value of the large size is, of course, that it provides larger and sharper images - most valuable qualities for rapidly bigd animals.

At one extreme, the mud-probing American Woodcock has eyes set high and back on the head, out of the way of vegetation and splattering mud. This position is also effective from preventing surprise attacks from behind.

Because of the location of the eyes, the What is the purpose of the coordinate system has more effective binocular vision of majes to the rear than of objects in front of it! The eyes of hawks and other predators are directed more toward the front, since they usually pursue prey in front of them. Owls nearly match man with their frontal eyes, but unlike human's their eyes are almost immovably locked in their sockets.

In compensation for this rigidity, they have flexible necks that allow brid to twist their heads at least not ! The rear wall of a bird's eye is densely lined with a sensory receptor layer of rods and cones that form the bbird, the surface on which images are formed.

The rods are sensitive to light, especially at low intensities; the more rods it has, the better a bird is able to see at mqkes or at night. Birds that are nocturnal active during the nightsuch as owls and goatsuckers, have more rods than cones. The cones function in bright light to form sharp images and distinguish shades of color. So cones are more numerous than rods in the retinas of diurnal active during the day birds.

Unique Bird Characteristics - What Makes A Bird A Bird? Birds were able to become flying machines largely through the evolutionary gifts of feathers, powerful wings, hollow bones, warm blood, a remarkable respiratory system, and a large, strong heart. This video quickly lays out the characteristics that make a bird a bird. Jan 11,  · A light hearted description of bird anatomy showing how they differ from humans and how they fly.

All birders are familiar with the occasional window strike when a bird inadvertently hits a window , and it is easy to prevent these accidental collisions. When a bird deliberately attacks a window, mirror, or other reflective surfaces over and over, however, unique steps may be needed to protect the bird from itself.

Some bird species are naturally aggressive and territorial. When they notice their reflection in a window, mirror, chrome bumper, reflective grill, gazing ball, or similar shiny surface, they assume it is a rival bird and will attack the reflection to try and drive the intruder away. They may fly against the reflection, peck at it, rake it with their talons , or beat it with their wings. They may also strike up aggressive poses and threat postures in front of the reflection between actual attacks.

While these actions do not generally cause severe injuries, they can lead to exhaustion that will make the bird more vulnerable to disease, malnutrition, and predators. While any bird may show a bit of aggression towards a competitor, species that are especially known to attack themselves as reflections include:. The degree of aggression and duration of the attacks will vary for each bird species and even for individual birds.

Attacks are most common during the breeding season when birds' competitive drive is highest and may begin as early as February or March as birds start to claim territory. Depending on the species, attacks could last just a week or two or may continue until late summer if the species raises multiple broods.

Only after the breeding season has ended will the aggression wane unless birders take steps to discourage these confused birds. Many of the best ways to stop birds from attacking windows are the same methods used to prevent bird-window collisions. The key is to break up the reflection the bird sees so it does not feel threatened by a non-existent competitor. Options include:. For the best results, the reflective area should be covered as thoroughly as possible, and using several techniques at once can minimize a bird's agitation.

If there are still mirrored surfaces several inches in size where the bird could spot most of its reflection, it may still feel threatened. If the bird is attacking a vehicle reflection such as a car mirror or chrome bumper, moving the vehicle to a different area may solve the problem because it will be outside the bird's preferred territory. If necessary, an opaque plastic bag or a cloth rag can be draped or wrapped over the reflective surface while the car is parked to keep the bird away.

Watching birds carefully can also help create solutions. For example, perhaps a bird only spots its reflection from a particular perch, and removing that perch may keep it from noticing the reflection and feeling threatened. Another temporary solution to stop a bird pecking windows is to make the area less bird-friendly to encourage the bird to find a less hostile territory for nesting. Removing birdhouses or several bird feeders, for example, may encourage aggressive birds to find a different area for raising their families.

While birders may miss their company, the birds will feel safer and less stressed in an area away from harassing reflections. NOTE: It is a violation of the Migratory Bird Treaty Act and similar legislation in many countries to capture or harm a bird, its nest, or its eggs, even with the best intentions. The bird should never be harmed to stop it attacking its reflection. Watching a bird fruitlessly attack its reflection over and over can be distressing for a birder, and doing so is exhausting and stressful for the bird.

Knowing why birds attack windows and how to stop them can help birders provide a safe, hospitable environment for birds to enjoy. Actively scan device characteristics for identification.
