Birds are feathered, winged, bipedal, endothermic (warm-blooded), egg-laying, vertebrate animals. With around 10,000 living species, they are the most speciose class of tetrapod vertebrates. All present species belong to the subclass Neornithes, and inhabit ecosystems across the globe, from the Arctic to the Antarctic. Extant birds range in size from the 5 cm (2 in) Bee Humming bird to the 2.75 m (9 ft) Ostrich.
The fossil record indicates that birds emerged within theropod dinosaurs during the Jurassic period, around 150 million years ago. Birds are the only members of the clade originating with the earliest dinosaurs to have survived the Cretaceous–Paleogene extinction event 66 million years ago.

As for Black-necked Swans, these beautiful birds are native to southern South America. The sexes are similar in plumage. They flock most of the year but are quite territorial when breeding. The males will chase other waterfowl, and almost anything else, from the vicinity to the nest. Incubation will last 36 days until the clutch of 4-5 hatches. The cygnets spend much of their time on the parents, back when not feeding.

Modern birds are characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. All living species of birds have wings, the most recent species without wings was the moa, which is generally considered to have become extinct in the 16th century. Wings are evolved forelimbs, and most bird species can fly. Flightless birds include ratites, penguins, and a number of diverse endemic island species. Some species of birds, particularly penguins and members of the Anatidae family, are adapted to swim. Birds also have unique digestive and respiratory systems that are highly adapted for flight. Some birds, especially corvids and parrots, are among the most intelligent animal species, a number of bird species have been observed manufacturing and using tools, and many social species exhibit cultural transmission of knowledge across generations.
Many species undertake long distance annual migrations, and many more perform shorter irregular movements. Birds are social, they communicate using visual signals and through calls and songs, and participate in social behaviours, including cooperative breeding and hunting, flocking, and mobbing of predators. The vast majority of bird species are socially monogamous, usually for one breeding season at a time, sometimes for years, but rarely for life.Eggs are usually laid in a nest and incubated by the parents. Most birds have an extended period of parental care after hatching.
Some species, particularly songbirds and parrots, are popular as pets. Other uses include the harvesting of guano (droppings) for use as a fertiliser.We invite you to join us as a member of our picture gallery.
