The oldest trace found of a bird as such, dating from 150,000,000 years, was called Arqueopterix lithographica (ancient wing engraved in stone). This fossil was considered as the link between the flying reptile and the birds that we know today.

Currently, birds have been reclassified according to some of their qualities:
  • Paleognathae (they are those large flightless birds)
  • Neognathae (they are the gallonserae like ducks, geese and swans) and

Characteristics of birds:

In birds, we have as a distinctive feature that they have feathers; this regardless of whether they fly, whether land birds or waterfowl. Its food is very varied.

Its main hallmarks are:
  • Have a peak
  • Have feathers
  • Two legs adapted to their respective environment
  • Two wings, in arms position, that are properly adapted to fly.

The birds have the characteristic of having hollow bones and specially hardened, adapted to lighten their body and therefore, that can fly.

The division of the birds can be established in:
  • Insectivores
  • Herbivores
  • Granivores
  • Carnivores (hunters)
  • Scavengers (fed with decomposed meat)
  • Omnivores (they feed on anything edible).

The reproduction of the birds, is through eggs, which must be fertilized previously; the birds form nests, where they lay their eggs, and then sit on them so that their high temperature allows them to hatch and hatch the eggs.

For this function, in some species, both male and female sit down to hatch them. In the body of the birds there is a strange phenomenon, its feathers sponge and its temperature rises above what is commonly so that its temperature helps the chicks hatch.

The eggs are formed by shell, clear (this is what forms the chick) and yolk; the latter is a source of food that the chick has for its subsistence during its stay in the shell.
