Learn about kinds of birds. Birds are omnivorous, warm-blooded animals that are ubiquitously found everywhere. There are fewer birds in urban areas than in rural areas, probably because of the lack of trees, mud and other sources of food.
The efforts of environmental groups as well as birdwatchers from all over the world have resulted in the continued conservation of bird species in danger of going extinct. Some of the kinds of birds that flock to cities are able to fend for themselves, especially when they go in groups, like pigeons.
The different kinds of birds are classified in two main groups and their respective subgroups. There are morphological and corresponding physiological differences between these groups and subgroups, and here are some of them.
Paleognathae is the first group of the kinds of birds still living up to this day. Many sources tell us that this is the older, less evolved type. This group is made up of subgroups Rheiformes, Struthioniformes, Tinamiformes, Apterygiformes and Casuariiformes. In this group are the flightless birds called ratites. Also included in this group is the ostrich. These kinds of birds have wings but their wings are not developed enough to make flight possible.
Some sources cite the skeletal system and the overall morphology of the sternum as the main factors why these birds have a different wing pattern compared to other groups. Paleognathes are defined by their bone architecture, especially in the palate region. Thus, we can assume that these birds make a different sound compared to the chirping of other birds.
Neognathae are the modern kinds of birds, with evolved wing systems allowing some of them to fly. Taxonomical classification places some flightless birds among these kinds of birds in the Neognathae clade, such as the domesticated chicken. There are various differences among the subgroups, particularly in brooding behaviour, diet, flight patterns and habitat. Most of the living species of birds belong to this group, and some of these are endangered. There are 34 orders in this clade, including the following:
Charadriiformes – These kinds of birds like to hunt for fish and other critters therefore build their nests near bodies of water. There are some members that like to forage in desert areas. Gulls and auks belong to this group.
Galloanserae – This is a clade within Neognathae and this is made up of land and water fowls.
Phoenicopteriformes – Flamingos belong to this group. Most flamingos are seen in the Latin American countries, particularly Argentina. One species is endemic to Asia and Africa.
Columbiformes – These kinds of birds like to interact with humans in urban and suburban areas, such as doves and pigeons. These birds are well-distributed all over the world and hold special meaning culturally. Doves are often seen as symbols of peace. Pigeons are kept as pets in some areas of the world.
Mesites – These kinds of birds are small in stature and some are flightless. They resemble pheasants, but with distinct differences in behaviour and appearance. Cranes are in this group. The members of this group are near extinction.
