Red Data Book
All about red data book Red data book is a list of species whose continued existence is threatened.
Red Data Book species are classified into different categories of perceived risk. Each Red Data Book usually deals with a specific group of animals or plants (for instance, reptiles, insects or mosses). They are now being published in many different countries. JNCC is responsible for some of these publications reflecting the status of some plant species types in Britain and Ireland.

Proponents of Red Books usually give the following reasons: the connection between illegal hunting and Red Books is unclear and not proven. Local biologists can be approached and bribed by illegal entrepreneurs with the same ease. Funds that are used to create these books do support local biological research. Additionally, regional Red Books allow for more accurate and diverse local environmental protection, like greater bird protection in cities and flora protection in Arctic regions Red data book of India
The book provides a central information source in organizing studies and monitoring programs on rare and endangered species and their habitat it is regularly consulted when developing and implementing special measures for the protection and rehabilitation of such species
The latest Red Data Book issue from 1996 contains 5 205 endangered species. The research and assessment of the situation of all known species of mammals and birds have shown that 25 % of the species of mammals and 11 % of birds are on the edge of extinction. It is estimated that 20 % of reptiles, 25 % of Amphibians, and 34 % of fish are under the same threat. In case we include into this group of endangered mammals those that have not arrived at this threshold so far but are very near to it, we can speak about 41 % of all species of mammals as of endangered. The most endangered species are the orders of rodents, chiropterans, insectivores, carnivores, primates and artiodactyls. In birds these endangered orders are: perching birds, parrots, galli birds, pigeons and doves, and gallinaceous birds. In reptiles these are: crocodiles, tuataras, tortoises and turtles. The highest number of endangered species of mammals is in Indonesia, China, India, Brazil, Mexico, Australia, New Guinea, Philippines, Madagascar and Peru. As far as endangered birds are concerned, the worst situation is in Indonesia, Brazil, China, Philippines, Columbia, Peru, Ecuador, USA and Vietnam.

Migration At the time of unfavorable conditions the habitats have to move towards the favorable conditions to survive, this is known as migration. Migration refers to directed, regular, or systematic movement of a group of objects, organisms, or people.
There are Two main types of migration
Bird migration Bird migration is the regular seasonal journey undertaken by many species of birds. Bird movements include those made in response to changes in food availability, habitat or weather. Migration is marked by its annual seasonality.

Human migration Human migration is movement (physical or psychological) by humans from one district to another, sometimes over long distances or in large groups. The movement of populations in modern times has continued under the form of both voluntary migration within one's region, country, or beyond, and involuntary migration (which includes the slave trade, trafficking in human beings and ethnic cleansing). People who migrate are called migrants, or, more specifically, emigrants, immigrants, or settlers, depending on historical setting, circumstances and perspective.
