Well, there was at no time a creature that woke up one day or was born one day and had fully developed wings. Who suddenly decided to leap from a tree
or off a cliff, with a leap of faith, and flew.
There are a number of animals today that have developed flight, but do not have wings.
That guy can 'fly' but has no wings or feathers..
as for why they sing, why are they also varied in many beautiful colours? Or as mundane as a rolled up newspaper.
Maybe they do enjoy singing. But I do not think they sing for pleasure.
I remember an experiment I saw once, where a certain bird had a certain intricate song. They wanted to learn if the song was learnt or instinctive so
they took some of these birds and separated them from birth. What the bird did, without any other birds to sing with, was develop a rambling noise.
Each new generation of the bird adapted some of it, and eventually they had a completely new song that an entire generation of birds all knew. As if
they were talking to each other but it was completely different to the song they had in the wild.
Might be they all decided that the radio sounded funny but they still learnt to sing along with each other... who really knows, but it serves a
communal purpose for a species at least we know.
