![]() These feet help the bird to perch and climb amongst the branches. Parrots have zygodactyle feet in which two toes point forward and two backward. They also sing to show how bold and aggressive they are. They also sing to make other males aware of their territory and warn them to keep away. Male birds sing to attract females to mate and breed. In most instances it is the male bird that sings. Only parasitic birds like the cuckoos need not hear the adult birds to produce a perfect song. The crude song they sing becomes the plastic or perfect song only after listening to their adults singing in their environment. ![]() Young birds hold the information required to produce a crude song in their genes. The songs that each species of birds sing is a tune that is specific to that species. Birds’ singing is different to birds imitating sounds. However, other birds are able to pick up these vocalizations throughout their lives.īirds can make two types of vocalizations. Some birds have to learn these vocalizations in a short period. The ability to learn to make these vocalizations differ in different species of birds. Some species of birds learn all kinds of vocalizations like singing and imitating sounds including the human voice. The added attraction is that parrots can imitate the human voice and are seen as being able to talk. Since parrots are pretty birds, they are very popular as caged pets. They are also a problem in the early stages of the cultivation when they get to the ground and eat the seed paddy as soon as it is sown in the field. These flocks could be the bane of paddy farmers when they descend on a paddy field and eat up the ripening paddy seed. Most species of parrots move about in flocks and are very noisy in flight and also as they go about looking for food. Parrots feed on grain, nuts, buds of flowers nectar from flowers and fruit. Parrots are fairly stout birds with hooked beaks. This helps them to blend with the leaves of the trees in which they move about. The parrots found in Sri Lanka are mostly green in colour. The lorikeet is a smaller bird and has a short tail. Of the five species, four are long-tailed birds and called parakeets. They belong to the order Psittaciformes and Family Psittacidae. In Sri Lanka there are five species of parrots. Sri Lanka too is a signatory to this convention. The highly endangered species are on the list made by CITES in Appendix 1 and all other species are on CITES list Appendix 2 and are considered vulnerable.ĬITES is an international convention, which has been signed by over 100 countries, designed to prevent the international trade of various species in order to stop their indiscriminate trade and to help conserve these species. The Convention on the International Trade of Endangered Species (CITES) has made the sale of all wild caught parrot species illegal. This threat is mainly because they will compete and use up the food resources available to the local birds. Some of these increasing flocks can be a threat to the ecosystems in which they have adapted themselves. Some of these caged birds, kept as pets, have been released or have escaped and have now formed feral populations. Though both types are popular caged birds, the cockatoos are more popular than the parrots as caged pets, since they vary in size and since most of these species are colourful. These birds when perched are always erect. In both types the upper mandible has a certain flexibility to enable it to crack the seeds and nuts, which form a large part of their diet. The shape of the beak, which is curved, characterizes these birds. They are in two groups, the true parrots in the family Psittacidae and the cocatoos in the family Cacatuidae. There are 353 species of parrots in the world. Layard’s parakeet (Alu Girawa) By Hafiz Issadeen – originally posted to Flickr as Layard’s Parakeet, CC BY 2.0,
