What makes the house sparrow unique?

               The house sparrow is unique, because almost everyone in the world is familiar with this little bird. It is below 20 cm in length, with a feather cover of grey and brown shades.

               These birds can live in mountainous and plain terrains alike. They are very social by nature and roost communally. They build nests in holes in walls and ceilings, with straw and garbage.

               They basically eat seeds and grains, randomly collected from the ground. But these birds can assemble in large numbers and can raid crops, causing very serious damage to cultivations. They do this especially during winter seasons.

               Also, due to their habit of destroying flower buds and vegetables they are often a headache to people cultivating kitchen gardens. They have a large number of enemies including cats and owls. 

Why is the tailor bird so called?

            As the name suggests, the tailor bird is a ‘professional tailor’. They are excellent architects, skilled in building a well-engineered nest from raw materials like leaves and fibres. First they construct a funnel, by stitching the edges of a broad leaf. If the leaf is not broad enough, they will manage it by sewing more leaves together. The stitching will be done with cotton or twisted vegetable fibres and the ends will be cleverly knotted so that they do not get loose. Once the leafy basement is strong and ready, they build a cup-shaped nest in it with soft fibres, hair, cotton wool or vegetables.

            These birds have a green upper body and rusty brown forehead and crown. Found in pairs or singly, they are well-adapted to living in scrubby forests, gardens, villages and busy towns. They feed on insects and caterpillars. They also like the nectar of certain flowers and can be found circling the blossoms for it.

            The tailor birds can be found almost anywhere in India.

 

Why is the red-vented bulbul considered as a common bird?

            The red-vented bulbul is the most common variety of bulbul. It is dark brown in colour. The feathers are such that the dark brown colour ends in paler shade at the edges. This gives a scale-like appearance to the breast and back. The back of its body is white in colour and is normally concealed under the wings and is noticeable while flying. The region under the tail, called the vent, is red which gives it its name.

            These birds are mostly found in gardens and light scrub jungles. Their major diet is berries. But they also eat moths and caterpillars. When the winged termites come out from their underground holes after the first rain, the red-vented bulbuls will be the first to reach the spot. Either they will catch the insects as they exit the ground or they will spring up with them and catch them in air.

            These are very noisy birds. These birds build their nests at a height of around 3 m. They are found in pairs or as small groups. These birds are native to India and Sri Lanka. 

What are the features of the Indian robin?

               The Indian robin is a very familiar, lively bird in our villages. It is notable by its permanently cocked up tail. The male birds of the species are brown and shiny black in colour. The under parts of the tail are in a deep chestnut colour. There is a white patch under the wings, which is normally hidden when the bird is at rest. The female bird is ash-brown in colour and the chestnut colour under the tail is slightly paler, when compared to that of a male bird.

               These birds are found in stony, grassy, shrub forest environments. They prefer living in dry regions. They like human presence and are commonly found perching on rooftops. Once settled, they don’t migrate anywhere. They feed on insects and caterpillars. They have a special liking for white ants and are found lingering around anthills. These birds are very common in India.

Why is the Eurasian collared dove different?

            The Eurasian collared dove is a medium-sized bird with a pinkish grey plumage.

            It gets its name from the black collar found on the back of its neck. It is more than 30 cm in length and its wing span can extend up to 55 cm in width.

            These birds choose to live in open woodlands, cultivated lands, villages and urban areas alike. They generally keep away from dense forests. They nest near human settlements, where food is easy to get and trees are available. They are found perching on wires and feeding on the ground. Seeds constitute their major diet.

            During flight, just before landing, they produce a harsh loud screeching sound which lasts for a few seconds. They tend to stay where they live and are not migratory.

            These birds are very common in India. Outside India, they are also found in Europe and other parts of Asia. They were introduced in North America in the 1980s.

What are the features of the laughing dove?

          The laughing dove is a small, thin bird with a brown and grey plumage. It has a patch of square speckles in black and reddish-brown colour on its neck, like a necklace. It also has a long tail and its call is quite different from that of other kinds of doves.

          These birds can be found in dry, rocky and bushy terrains. But they are also well adapted to living in cultivated lands, villages, parks and urban areas. These birds are so used to humans, but their nature does not attract much attention. They eat seeds in pairs, usually from the ground. Generally, these birds like to live in a particular locality. But sometimes, they are also found moving from place to place. Some of these birds that had tags attached to them for identification were discovered to have moved from Gujarat to Pakistan. They covered more than 200 km and were landing on ships in the Arabian Sea, when they were exhausted.

          Laughing doves are very common in India, where they are also called little brown doves. Sometimes, these birds are also called palm doves or Senegal doves.
