The word "bird" is spelled as /bɜːd/ in IPA phonetic transcription. The "b" and "d" sounds are produced by closing the lips and the tongue on the alveolar ridge, respectively. The vowel sound is represented by "er" (as in "herd") in the middle of the word, which is the so-called "rhotic" or "r-colored" vowel. The final sound, "d", is also made by touching the tongue to the alveolar ridge, but with vibrating vocal cords. The spelling of "bird" may seem straightforward, but mastering English pronunciation requires much practice and attention to details.
A bird is a warm-blooded vertebrate animal belonging to the class Aves, typically characterized by feathers, beaks, hollow bones, and the ability to fly. Birds are found in various shapes, sizes, and colors, with around 10,000 different species known to exist worldwide. They are spread across diverse habitats ranging from forests and deserts to mountains and oceans.
Feathers are a defining characteristic of birds, serving multiple purposes. They provide insulation, enable flight, display courtship rituals, and assist in camouflage. Birds possess beaks or bills, which vary in shape and size based on their feeding habits. They use these beaks to eat a wide range of diets, including fruits, insects, nectar, fish, and small animals.
Birds have a unique respiratory system, with air sacs connected to their lungs, allowing for efficient oxygen exchange during flight. Although most birds can fly, there are certain flightless bird species, such as penguins and ostriches, which have adapted to their respective environments.
Birds are known for their vocalizations, which vary greatly between species, and are often used for communication, mating calls, territorial defense, or warning signals. They also possess a highly developed sense of vision, enabling them to locate prey, navigate during migration, and display intricate plumage patterns during courtship.

The word "bird" originated from the Old English word "brid" or "bridde". It can be traced back to the Proto-Germanic word "briddiz", which meant bird. This word ultimately derived from the Proto-Indo-European root word "bhréh₂d-", which referred to breaking or cracking sounds, similar to the chirping or singing sounds made by birds. Similar cognates can be found in other Germanic languages, such as German "Vogel" and Dutch "vogel".
