Well, birds fly because they can...& to find food, to escape & to find friends...maybe to escape the weather conditions too.
Wouldn't you?

aaah, the evolution of flight! Interesting question. It's generally suggested that feathers evolved as an insulating measure, like fur in mammals, because birds are warm blooded like us (and since birds are dinosaurs, this strongly suggests at least some dinosaurs were warm blooded too- not cold blooded reptiles!). Now, with time, these feathers became useful in gliding (I'm pretty sure that most people go with the idea that flight in birds evolved through a gliding stage- the little pre-birds hung around in trees and would glide from branch to branch), and eventually true flight feathers evolved! The earliest known flight feathers are seen in archaeopterix, one of the most famous ever fossils (or 6, actually- one in London, one in Berlin, and some others kicking around). These fossils are all Jurassic in age, or aroung 150 million years old! Which is pretty old, I think you will agree. For whatever reason, only avian dinosaurs survived the end Cretaceous extinction, which killed off all other dinosaurs, and left us with birds! Flight is great, and very useful! Insects were the first to fly, back in the Carboniferous period, but there were also flying reptiles (pterosaurs) and there are flying mammals (bats)!!

somewhat... this is humorous you element out this. there replaced into city virtually an hour north of right here that keen to poison its pigeons about 2 months in the past. They used the incorrect quantity of poison, although, and had to declare an emergency for an afternoon because dozens of pigeons were dropping useless out of the sky on properly of human beings. that is a real tale, look it up. Schenectady. the fact is birds do not habitually tutor any signal of ailment till they're waiting to die. The day they die they have an inclination now to not fly. that is a flocking element... any fowl that shows weak point in a flock is careworn or killed with techniques from different birds, so as that they have got a tendency to die quietly off with techniques from themselves... and out of sight.

its just they way they have evolved, animals will always diverse to fill all habitats. The air is a habitat like water and land. Birds have filled a niche and air travel is blatantly superior to other forms and one of the safest i am told.
