BIRDS

Birds are a collection of endothermic vertebrates which might be prominent via way of means of their feathers, toothless beaks, a excessive metabolic rate, a four-chambered heart, and a mild skeletal build. All birds are eggs, the women lay numerous eggs with tough shells, the embryo grows interior and develops till it is prepared to hatch, and it emerges into the sector as a entire chick. Birds are unfold all around the world, consisting of Antarctica, and that they inhabit quite a few habitats and herbal habitats, a number of which might be capable of continue to exist in man-made habitats including towns and villages. Birds are available quite a few shapes, colors, and sizes, from the 5-centimeter (inch) bee

buzzer to the 2.75-meter (9-foot) ostrich, and from the acquainted raven crow, to the iridescent lorikeet.

Scientists have verified that birds are the most effective surviving taxon of dinosaurs, as they're their direct descendants. Birds are prominent from the sizable majority of vertebrates in that they're capable of fly, and this cappotential isn't shared via way of means of vertebrates besides for bats. There is not anything amongst animal companies that arouses human pastimes and captures the longing of such creatures with

their colors, intensity, and difference in air, land and sea, so that they've grow to be a great challenge for examine and a classy detail for human taste. Man has triggered numerous environmental troubles from pollution, pest infestation and overhunting, mainly the destruction of herbal habitats, that have had a intense effect at the populations of many species of birds.

Birds are endothermic vertebrates, and they are distinguished among contemporary organisms by their feathers and body shape, and by laying eggs that contain a thick outer shell, a light and sturdy skeleton, a four-chambered heart, and no teeth.  Birds multiply all over the world and inhabit all natural habitats, and vary greatly in size, the largest of which is the ostrich, which reaches 3 meters in size, and the smallest bird ever is the bee hummingbird, which is 4 centimeters in size.  The four-legged group of birds sits on the throne, as the most numerous group in terms of other species, with an estimated number of about 9 thousand species, and more than half of them belong to the order of passerines or passers-by, also known as songbirds. 

 

The most prominent types of birds

There are approximately 10,000 species of birds in the world, which are found in different regions. Birds are classified into 30 main groups, among which there is a species division. Among the most prominent types of birds are the following: [3] Birds of prey include hawks, eagles, eagles, and others. Species in this class reach 300, and they are carnivorous (predatory); It feeds on fish and small mammals, and is spread all over the world. Quails fall under these fifteen species and are found in grassy areas of Europe, Asia, Africa and Australia, feeding on worms and insects, and incubating their young after the eggs hatch. Cassowary birds This type of bird does not fly, and has a neck and head without feathers, and is found in Australia, Guinea and Britain, and these birds are threatened with extinction. There are 160 species of cuckoos and turacos around the world, mainly in the savannah, and they feed on insects and larvae. Flamingos, their scientific name (Flamingo), these birds feed on small marine animals, and they are distinguished by their scarlet or pink color, and they are found in tropical and subtropical regions, specifically in South America, the Caribbean, Africa, India and some areas of the Middle East. Small birds (game birds) are the most common birds in the world and include chickens and turkeys, of which there are 250 species, of which there are billions around the world. This bird falls under 100 species, and is classified as a carnivore, and is characterized by long legs that enable it to stand in the mud without drowning. Hummingbirds The most important characteristic of this species is their small size and thin beaks. The king of hunters is a carnivorous bird, distinguished by its large head compared to its body, and pointed wings, and it feeds mainly on bees. Kiwi bird This bird includes 3 main species, native to New Zealand, and in this species the female lays her eggs, and the male incubates the eggs for 70 days.                                                                                                                                               

Birds have two legs

The bird has thin legs and feet in order to suit the different lifestyles in nature, where the thin leg bones tend to be larger than the bones of other mammals that are similar in size and body shape to them.  The reason for this is that it must be very strong to be able to carry the body of the bird, as it is mostly standing on two legs, while the rest of the mammalian species has four legs, all of which are tasked with carrying the weight of the body.

Bird feed

If you feed birds, you now no longer handiest offer them with excellent nutrients, however you furthermore mght assist them support their immunity towards parasites that assault younger birds of their nests, consistent with a examine posted withinside the Journal of Applied Ecology. In their examine, the researchers targeted at the "blue sparrow", a songbird that feeds on bugs or animal waste and lives withinside the Americas. The examine discovered that "imparting birds with dietary dietary supplements might support the overall fitness of birds," noting on the equal time that "the ones dietary supplements may additionally have blended effects on animals that address those parasites." The examine aimed to decide the impact of meals supplementation on growing the protecting abilties of birds withinside the face of parasites, and determined that the birds that acquired dietary dietary supplements had a 75�crease in the proportion of parasites, in comparison to different birds that did now no longer acquire dietary dietary supplements. Dietary supplementation turned into secondary to blood loss, even as it improved the antibody reaction to parasite resistance. Sarah Knutti, assistant professor withinside the Department of Ecology and Evolutionary Biology on the University of Connecticut, and lead researcher, explains that "parasitic flies may be determined withinside the nests of many hen species, which critically impacts the lives of younger people. These flies lay their eggs withinside the nests, and whilst The larvae that feed at the blood of younger birds emerge via way of means of making holes of their skin. The effects of the examine imply that imparting birds with dietary dietary supplements, specifically early withinside the breeding season, will increase their capacity to withstand dangerous parasites. In the case of the "blue hen", "Knuti" says withinside the announcement accompanying the examine: that the nests appear to be usually greater tolerant to parasitic flies, that means that they'll undergo massive portions of parasites with out critically affecting them, whether or not on their increase or on their survival. existence, even though the parasite attracts a number of the little hen's blood. To discover how the hen's immune reaction to the parasite is affected, and whether or not there's a positive time withinside the breeding season whilst extra feeding for birds turns into greater effective, the researchers organized two hundred containers in order that they act as nests, in northern Minnesota, to comply with the birds' eggs, and upon hatching, they determined These birds feed every different with food of stay worms. Knuti additionally monitored the increase and existence of younger birds in order that they might fly. After leaving the nests, the wide variety of parasites interior them turned into determined. It turned into determined that the younger birds that had been surprisingly fed had a better survival fee and decrease blood loss than those who did now no longer get extra feeding. Knutti adds: “If the younger birds had been now no longer fed, all of the nests contained parasites of as much as one hundred twenty five flies according to nest. If the younger birds had been fed, there has been little or no or no parasites. Thus, the effects recommend that the extra feeding will increase birds' capacity to kill parasites. As for the interplay of antibodies, it turned into proven that it turned into susceptible or non-existent withinside the absence of extra feeding, even as it turned into sturdy whilst feeding the younger, and thus, the excessive degrees of antibodies brought on the dearth of parasites withinside the nest, and it turned into additionally proven that the timing of feeding the birds It makes a great difference, the sooner the feeding, the greater useful it turns into. And at the function of intestine microbes withinside the immune response of birds, the examine proved that this microbial surroundings is comparable whether or not the birds acquired meals or now no longer, with minor differences. There is a relative abundance of Clostridium traces in fed birds, and there's a correlation among degrees of antibodies and parasites, this means that that greater Clostridium approach greater antibodies and less parasites. Clostridium stress is one of the bacterial species of minute size, and it includes spores able to resisting chemical and bodily influences, and it could additionally stay at low temperatures. Knotti added, in statements to Al-Salam, that "latest research have proven that intestine microbes may also have an effect on the increase and safety of the immune system, in exceptional animal models, in addition to in younger blue sparrows, wherein the bacterial surroundings interacts with the immune system. However, greater empirical research are wanted to check this relationship. Knutti factors out that there are preceding research on exceptional breeds of birds which have validated that birds that get ok nutrients are in excellent shape. She explains that the trouble is that those birds are in sturdy touch with their counterparts, which exposes them to the opportunity of contamination with different kinds of parasites, however the present day examine turned into carried out on a neighborhood hen subsequent to its nest box, and consequently the hazard of blending with different traces turned into susceptible, which calls for greater destiny research.
