MY PHOTOGRAPHER BEAUTIFUL BIRDS

Bangladesh is a home of different kinds of birds where different various kinds of birds are found.
They differ in size; color; and habit.
Put very simply our native (birds) in New Zealand are so unique because they evolved over many years without predator mammals. Millions of years ago the New birds land mass broke away from what is today the continent of Australia, before mammals achieved the status they have today. The only three mammals on known to have been here before human arrival where bats?
Generally speaking our birds then evolved in an ecosystem where there were only other birds predatory. They adopted defence mechanisms to prevent detection and also tended to be largermammals longer living but slower breeders, than birds elsewhere in the world.my country Bangladesh wow beautiful birds.
