The success of bird life has been largely thanks to the nice variety and ingenuity displayed find situations suitable for providing food and allowing reproduction. Their powers of habitat selection allow diversification of species by reducing inter-specific competition.

Species living within the same area rarely eat the identical food, especially if it’s scarce. they obtain the means of life in most various ways. Nevertheless each species nests during a limited sort of habitats and feeds during a limited sort of habitats.


The birds only eat the food under unusual conditions of starvation, but many birds are more wide-reaching in tastes and a fewof those are among the foremost common, for example rooks, starlings, thrushes, blackbirds, and gulls. they’ll remember to go to an abundant source of supply .

Food selection thus depends on species-characteristic motor patterns and structures, whose use varies to suit the circumstances. In young birds these actions aren’t necessarily associated with appropriate objects or situations. (see Hinde, 1959).


Great mobility has made it necessary for birds to develop specific means for recognizing their fellows, their enemies, and their competitors; from this power an elaborate social life has developed in many species.

In spite of their freedom many birds aren’t individualists, they live much of their lives together in flocks; the unit of life is larger than the ‘individual’ body.

Species feeding on the bottom, like rooks, starlings, and partridges, commonly move about in groups during the winter and acquire the advantage that the alertness of every single bird serves to warn for several.


Among the remarkable devices of birds is their habit of seasonal movements to get the advantage of the favorable conditions offered in additional northerly regions only during the summer. The familiar migrations are those north and Marine birds also may make extensive migrations.

Birds certainly don’t learn the routes from their elders, indeed the young often leave first. However, juveniles return only approximately to their birthplace, whereas older individuals return to their old nesting sites. Powers of homing are remarkable in birds, aside from migration.


The element of threat in singing and display features a further importance in connexion with the territories that a lot of birds establish around their nests. Eliot Howard especially has developed the concept of bird territory as a results of observation mainly of warblers and buntings.

For instance, within the warblers (Sylviidae) the males, getting back from migration some days prior to the females, establish themselves on a specific area, singing often from a tall tree or other headquarters near its centre.

As other males arrive boundaries develop, so the region becomes shared into variety of areas, initially each of about 2 acres, later reducing to 1.

When the females arrive they partner off with the males and throughout the full season the 2 birds occupy one territory, driving off other birds that encroach and during this way establishing quite definite boundaries to their area.

Howard supposed that this arrangement was widespread in birds which it has;


1. Uniform distribution over the habitable area is ensured.

2. Females are assisted to seek out unmated males..

3. the 2 birds are kept together and don’t seem to be distracted by wanderings faraway from home.

4. it’s possible to seek out adequate food without travelling faraway from the nest, this being especially important during the amount of incubation and rearing of the young.

By establishing a territory he ensures the chance to display and copulate without disturbance, a really necessary precaution since he’s vulnerable at these times and other individuals may attack a copulating male, trying to displace him.


The male and feminine birds don’t differ greatly and also the ceremonies are mutual. One bird may dive and are available up near the opposite and that they then approach with necks stretched on the water, giving a curious ripple pattern that Huxley called the plesiosaur appearance.

As already mentioned, courtship may include ritual feeding of the opposite sex during display and infrequently before coition, as an example, in pigeons and gulls, and this again may have a symbolic function.


As in every other aspect of their life we discover the nest of birds varies in some ways to suit different manners of life. This fidgeting may take various forms, including making a ‘scrape’ within the memorizing pieces of grass.

Sometimes the male brings the fabric and also the female uses it. She may do the fetching similarly, perhaps in the middle of the lazy male; or he may don’t have anything to try to to with the entire business.

The integration of those movements into a functional sequence of behaviour depends, however, on experience.
