Okay, I'm not sure if there are any fans on here, but has anyone read any of the books in the Silverwing series? There are four books at the moment ((one has just gotten released)).
The books are by Kenneth Oppel. In my opinion, he does an excellent job writing about the bats. He doesn't use color to describe the scenes, but instead he uses other very descriptive words.
Here is a picture of the covers and a summary ((taken from the back of the books)):
Silverwing:

Quote:
Shade is a young Silverwing bat, the runt of his colony determined to prove himself on the long and dangerous winter migration to Hibernaculum, millions of wingbeats to the south. During a storm, Shade is swept out over the ocean -- away from his family, his friends, and the only life he has ever known. Alone and frightened as winter fast approaches and temperatures plunge, Shade sets out on a remarkable journey to rejoin his colony to the south.
Sunwing:

Quote:
In search of his father, Shade discovers a mysterious human building containing a vast forest. Is this paradise the fulfilment of Nocturna's Promise to return the bats to the light of day? Shade and his Brightwing friend Marina aren't so sure. Shade has seen Humans enter the forest and take away hundreds of sleeping bats for an unknown purpose. And where is Shade's father?
It isn't long before Shade and Marina are swept up on a perilous journey which takes them to the far southern jungle -- the homeland of Goth, now king of all the Vampyrum Spectrum: cannibal bats with three-foot wingspans. With the help of an abandoned owl prince, and General Cortez's rat army, Shade must use all his resourcefulness to find his father -- and stop Goth from harnessing the dark powers of Cama Zotz to create eternal night.
Firewing:

Quote:
The earth heaves and splits in a terrible quake and Griffin, a Silverwing newborn, is sucked into a fissure deep below the earth. Shade, Griffin's father, soon realises that his son has been drawn into the Underworld, and embarks on the most dangerous of journeys to rescue him. Shade knows he must find Griffin quickly, but something else is hunting Griffin -- a deadly foe Shade hoped he would never see again.
Who will find Griffin first? And who will survive to embark on the perilous journey back to the land of the living?
Darkwing ((it's basically about the first bats)):

Quote:
Dusk can't help it. From the moment his father pushed him off the tree, he has yearned to flap. But in a colony where being different means being shunned - or worse - Dusk knows he must glide like the rest of them and keep his secret to himself.
Carnassial also has a hidden desire. And when he finally gives in to his instincts, a vicious predator is born. He knows the world is changing, and he's determined that his kind will take over as rulers of the beasts.
The battle for survival - and the future - has begun.
