Introduction
"Birds are vertebrate animals of the class Aves. They are winged, have two feet, are warm blooded and oviparous.
It is estimated that the world Avifauna has at least 10,000 living species. They inhabit Earth from one Pole to the other. According to studies based on fossil remains, birds evolved from Theropod dinosaurs around 160 million years ago (Jurassic period).
Since birds have survived on Earth for a very long time, I believe we have a lot to learn from them. The world as we know it has many secrets that will take a very long time to be discovered. More observation and research is needed.
Note:
Avian101 website is photography oriented. Photos of birds is my main objective. My blog complements this site with a wealth of information about the habits of birds."
