The fan-throated lizard is a species of agamid lizard found in India, Sri Lanka, and parts of Pakistan. The species is found mostly on the ground in open ground patches in thin forests. When disturbed this lizard sometimes runs with a bipedal gait. Wikipedia Crocodiles are well-known for their armored skin, sharp teeth and powerful jaws, but the ancient reptiles' mating behavior is just as striking as their appearance. There are 23 crocodilian, or "crocodile," species alive today, including true crocodiles, alligators and gharials. And though mating behaviors vary, different species share many similarities, said Australian croc specialist Adam Britton. The mating dance involves almost all the senses. Males begin by bellowing above water, while producing low-frequency infrasound, which humans cannot hear. "You can feel the vibrations traveling through the water and you can even see pressure waves.(LiveScience.com) The Little Tern (Sternula albifrons or Sterna albifrons) is a seabird of the tern family Sternidae. It was formerly placed into the genus Sterna, which now is restricted to the large white terns. The former North American (S. a. antillarum) and Red Sea S. a. saundersi subspecies are now considered to be separate species, the Least Tern (Sternula antillarum) and Saunders's Tern (Sternula saundersi). This bird breeds on the coasts and inland waterways of temperate and tropical Europe and Asia. It is strongly migratory, wintering in the subtropical and tropical oceans as far south as South Africa and Australia. There are three subspecies, the nominate albifrons occurring in Europe to North Africa and western Asia; guineae of western and central Africa; and sinensis of East Asia and the north and east coasts of Australia. The Little Tern breeds in colonies on gravel or shingle coasts and islands. It lays two to four eggs on the ground. Like all white terns, it is defensive of its nest and young and will attack intruders. Like most other white terns, the Little Tern feeds by plunge-diving for fish, usually from saline environments. The offering of fish by the male to the female is part of the courtship display. This is a small tern, 21–25 cm long with a 41–47 cm wingspan. It is not likely to be confused with other species, apart from Fairy Tern and Saunders's Tern, because of its size and white forehead in breeding plumage. Its thin sharp bill is yellow with a black tip and its legs are also yellow. In winter, the forehead is more extensively white, the bill is black and the legs duller. The call is a loud and distinctive creaking noise.(source-wikipedia)

Coots are omnivorous, eating mainly plant material, but also small animals and eggs. They are aggressively territorial during the breeding season, but are otherwise often found in sizeable flocks on the shallow vegetated lakes they prefer. At least some coots have difficulty feeding a large family of hatchlings on the tiny shrimp and insects that they collect. So after about three days they start attacking their own chicks when they beg for food. After a short while, these attacks concentrate on the weaker chicks, who eventually give up begging and die. The coot may eventually raise only two or three out of nine hatchlings. A group of coots may be referred to as a covert or cover.(source-wikipedia)

The sparrows are a family of small passerine birds, Passeridae. They are also known as true sparrows, or Old World sparrows, names also used for a genus of the family Passer. They are distinct from both the American sparrows, in the family Emberizidae, and from a few other birds sharing their name, such as the Java Sparrow of the family Estrildidae. Many species nest on buildings, and the House and Eurasian Tree Sparrows in particular inhabit cities in large numbers, so sparrows may be the most familiar of all wild birds. They are primarily seed-eaters, though they also consume small insects. Some species scavenge for food around cities and, like gulls or Rock Doves, will happily eat virtually anything in small quantities.(source-wikipedia)

The White-browed Wagtail is a resident breeder in India and is endemic to the Indian subcontinent. It is found south of the Himalayas, east of the Indus system and to the west of Bangladesh. It is rare in the higher altitude regions but has been seen in Ladakh on the edge of the Tibetan plateau. In most of India it is found below 1000 m but in southern India it goes up into the hills up to 2200 m. It is very rare in the Indus valley area. It is absent from the Sind region of Pakistan. It is found in open freshwater wetland habitats. It is one of the few Motacilla wagtails that has adapted well to urban habitats and is often found perched on overhead water storages in residential buildings. It is a rare winter visitor to Sri Lanka and have possibly extended their range in recent times.(source-wikipedia)
