The nf Birds are warm bodied creatures with wings body temperature of birds is generally higher than that of humans, so they seem warm to the touch Birds lay eggs which they incubate until hatchingor, in some cases, get some other bird to do the incubating. In some species such as our songbirds, the youno hatch naked and helpless and must be fed and cared for by a parent bird. Others, like the chickens and their relatives, produce down-covered young that are able run about and feed themselves. They are still dependent for protection upon adult birds. Birds range in size from thumb-sized hummingbirds to ostriches larger than a big man. Most birds, of course, fall somewhere between these two extremes. One common bird, the American Robin is about 10 inches in length, approximately the handspan of a large man. The smallest american birds are some species of hummingbird that could nest and raise a family in the cupped palm of a child. The largest are the cranes and herons, which, when standing erect, are almost eye-to eye with a human adult. The nearly extinct California Condor has a wing span of aimost 10 feet, and the Bald Eagle spans 7 feet. Birds walk, run, hop, swim, perch, cling, fly and even dig. They live in woodlands open areas, cities, farms, lakes, swampseven the open ocean. They lay their eges and raise their young in holes in the ground, in nests of varying complexity in vegetation or on the ground, in holes in trees, in human-constructed nest boxes, and in or on various parts of buildings. ROCK PIGEON The Rock Dove or Rock Pigeon is a member of the bird family Columbidae. In common usage, this bird is often simply referred to as the "pigeon. The species includes the domestic pigeon, and escaped domestic pigeons have given rise to feral populations around the world. Wild4 Rock Doves are pale grey with two black bars on each are wing, although domestic feraland pigeons very variable in colour and pattern. Scientific Name: Columba livia Kingdom Animalia Phylum: Chordata Class: Aves Order: Columbiformes Family: Columbidae Genus: Columba Species: C. livia DESCRIPTION: The rock dove has a dark bluish-gray head, neck, and chest with glossy and yellowish, greenish, reddish-purple iridescence along its neck and wing feathers. Females tend to show less iridescence than the males. The bill is dark 2 dark bands across the grayish-pink. wings are seen in most pigeons, and 1 bluish-gray band across the tail. Rock doves and feral pigeons can be divided into large number of different phenotypes, or groups based on outward characteristics. Some of these classifications are the blue-bar, blue checker, dark checker, spread, and red phenotypes. Body Length: 33 cm Geographic Range: Wild Columba livia are native to Europe, North Africa, and all of outhwestern Asia. Feral pigeons are found worldwide, including throughout is not North America. It should be noted that occurrence within this range evenly istributed. their heads forward and PEnaviour: Pigeons generally walk or run while bobbing often seen direct Pigeons are most Packward.

Habitat: Feral live in old farm buildingsi agriculture or open shrub vegetation. pigeons rural areas. In cities, the skyscrapers tend ta take the place of their natural clit surroundings. Food Habbit: Rock doves feed in the early morning and in the mid-afternoon on the open ground. They eat mainly seeds. Studies of pigeons in a semi-rural part of Kansas found that their diet includes the following: 92% corn, 3.2% oats, 3.7% chery. along with small amounts of knotweed, elm, poison ivy, and barley. In cities, feral pigeons also eat popcorn, cake, peanuts, bread, and currants. Female rock doves need to eat a diet somewhat higher in protein and calcium in order to have the nutritional resources to lay eggs. Economic Importance: Eaten by humans and used for laboratory research. for Humans Positive Economic Importance: A large number ofpigeons living in a small area can be a for Humans a nuisance to farmers. Some diseases (e.g.), Negative histoplasmosis) may be spread in pigeon droppings. Conservation Status: Since pigeons are often fed by well-meaning city dwellers, their numbers are high. Wild rock doves also have no special status. ROSE-RINGED PARAKEET The Rose-ringed Parakeet (Psittacula krameri), also known as the Ring-necked Parakeet, is a gregarious tropical Afro-Asian parakeet species that has an extremely large range. Since the trend of the population appears to be increasing, the species was evaluated as Least Concern by parakeets are UCUCN 2012.Rose-ringed popular as ratescommemorates thethe Austri naturalist pets.

It is very Belgiur 25-30 yrs. parakeets averages Lifespan: xpected lifespan of rose-ringed and bird. Behaviour: Rose-ringed Parakeet is a foolhardy opportunistic It has ha.oeen introduced as cage-bird, but this species is able to adapt very well. It lives in moremo or less large groups in most of the big cities. In their native areas, they gather:in order to invade grain and fruit crops, and they also may be found in granaries wher.ere they open the grain sacks with their hooked bills. They often quarrel aroundthe food sources. During the breeding season, the groups disperse. Some courtshi displays show the female rolling the eyes while twittering, and drawing semi-circle with the head while she moves the wings. At the same time, the male struts.
