a. Birds;

b. Dingos;

c. The world’s famous classification.

1. Every animal is known by two sorts of names. The scientific name, which is made from Latin or Greek words, remains the same all over the world. The first word of a scientific name places the animal in a genus with other animals, closely related to it. The second word is the animal's species.

The common name varies from country to country according to the language spoken. The common name of a species uses capital letters, e.g. Red Kangaroo. However, the common name of a group of animals, such as kangaroos, takes a lower-case letter.

2. Unlike domestic dogs, the female Dingo has only one breeding cycle per year, and a Dingo's teeth and skull differ from those of domestic dogs. Its most likely ancestor is the Indian Plains Wolf.

Dingos live in a well-defined home range, which may be shared with others. Individuals hunt small game on their own, but join to take larger prey. A group may consist of a breeding pair and younger animals. Dingos interbreed with domestic dogs.

3. Worldwide, there are about 8,800 species of living birds. Over 760 species of birds have been recorded from Australia and the oceans nearby.

A bird's plumage may account for up to 15% of its total weight, its skeleton only 5%.

Most birds have 1,500 to 3,000 feathers. A swan has up to 25,216. The protein of which feathers are made is also found in lizard skin.

The fastest flying birds can reach speeds in excess of 20 meters per second. Small birds on migration may cover 1,000 kilometers non-stop in 24 hours.
