Blue-Belly Gasglider

The blue-belly gasglider split from it's ancestor. Some Mini Gasgliders flew too far up and found themselves in the Troposphere. There, they found shelter within the Cloud Sweeper and evolved into the Blue-Belly Gasglider. As well as nesting in these cloud sweepers, they have also shifted their diet into eating the Windglobe Worm. Their beaks have sharpened in response to this new diet. Their crests now have undergone Sexual Dimorphism with males being big and bright, while females are short and dull. Their gas bladder has gotten bigger still.

Their torso has shifted into a more hover-like appearance. Their tail now is able to grasp their young in flight if their cloud sweeper goes down. It's wing blades have become longer and sharper, so they can hang on to their cloud sweepers during storms, as well as for courtship and hunting. They have also developed nose sacs for more amplified calls. Although they nest as a pair with their young, the males/females hunt in flocks of up to 40 individuals that hunt after much bigger swarms of Windglobe Worm. Males fight for the right to mate by dueling with their blades. To attract a mate, a male stands on all fours and squawks on a cloud sweeper. They have 3-4 young a year and live for 15 years.
