Ornithology

Ornithology is the study of birds. There are five major groups of vertebrates; fish, amphibians, reptiles, birds and mammals. With further examination, scientist have begun to see where birds could still be grouped with the reptiles. Personally, I think birds have diverged and evolved enough to be their own group of vertebrates. Birds are warm blooded and have four chambered hearts. Reptiles are cold blooded and have three chambered hearts.

Birds have feathers and generally can fly. There are flightless birds like the Ostrich or Emu. Chickens only fly enough to cause a bit of trouble for the Chicken owner. Birds lay eggs with hard shells to prevent the contents from drying out. Their bones are hollow.

Birds are special in that they are some of few wild animals that people can be familiar with. Their ability to fly has fascinated man with their relationship between Earth and Heaven. A lot of mythology is attached to birds. Interesting enough, finding a dead bird on your porch means you will experience a new beginning.

Two of my favorite birds follow.

  1. Hi Ann - can't disagree with Ornithology - love looking at the birds - just wish I knew more, and that the 'thugs' (jays, rooks, magpies, seagulls) weren't around ... lovely photos - cheers Hilary
