What is a bird?

A bird conists of a lot of parts:  1) beak, 2) head, 3) iris, 4) pupil, 5) mantle, 6) lesser coverts (type of feathers), 7) scapulars (type of feathers), 8) median coverts, 9) tertials (type of feathers), 10) rump, 11) primaries, 12) vent, 13) thigh, 14) tibio-tarsal articulation, 15) tarsus, 16) foot, 17) tibia, 18) belly, 19) flanks, 20) breast, 21) throat, 22) wattle.

A bird has some unusual features to its other vertebrate friends that help them fly. The bones are very light-weight. The spine is especially flexible and the forelimbs are modified into wings.

Birds don’t have a urinary bladder. Their digestive system is unique as they have a gizzard that contains swallowed stones for grinding food to compensate for their lack of teeth.

Birds breathe by taking air in which bypasses their lungs which mostly goes into a posterior air sac that fills with the air fills the bird with air to help with flying. When the bird exhales, the air flows out of the sac and is forced into the lungs so that the birds lungs are always getting a supply of fresh air when they breathe.

The eyelids of birds are not used for blinking and most birds cannot move their eyes. Birds with eyes on the front of their heads (for example owls) have binocular vision. Birds can detect ultra-violet light which is invisible to you and I but helps them find a mate.

Birds have feathers which help them fly and provide insulation and help them regulate their body temperature. The arrangement and look of the feathers will vary from species, sex, habitat etc. Birds will groom their feather daily because when they brush away the foreign particles they are actually applying a waxy goo that protects their feathers’ flexibility and stopping the growth of bad bacteria and feather parasites.

 

 

Did you know? No matter what a bird looks like, birds and people have always been a part of each other’s lives. Sometimes we help each other through cooperative efforts like honey gathering. Other times birds have benefited from human activities, and people have certainly benefited from birds as a food source and agricultural requirement.
