Ornithology is a branch of zoology It concerns the study of birds. Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. The science of ornithology has a long history and studies on birds have helped develop several key concepts in evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation.
While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across taxonomic groups, and the number of professional scientists who identify themselves as “ornithologists” has therefore declined. A wide range of tools and techniques is used in ornithology, both inside the laboratory and out in the field, and innovations are constantly made.
There are approximately 10,000 to 11,000 living species of bird existing on this planet and altogether, 25 different orders of bird including fowl, barbets, doves, raptors woodpeckers, parrots, and lot more. All these bird species are classified into the Kingdom Animalia.
Ornithology explains to us about the unique characteristics of birds, which includes:
- Migration: There are several species of birds that migrate long ranges and to a different place in search of food, shelter and also in search of warm or cold conditions and also in search of best environmental specifications.
- Mating Behaviors: There are many species of birds that mate for only one season, while others mate multiple times during one season.
- Vocal call or a song: There are few species of birds, which produces a type of vocal call or a song, which is used for a variety of purposes including:
- Warn off predators.
- Attracting its mate.
- Establishing territory.
- To identify their own offspring.
- Sexual and Species identification.
- Some birds also sing-song to mimic or imitate.
