Petrie gasped as he saw the tree-trunk blocking their escape route... or at least, blocking the escape of the others. The flyer hovered above them, his heart hammering in his small chest, as he tried desperately to think of something he could do to help. A crashing of undergrowth from behind, hissing, snapping, and he turned to see dark shapes rushing towards them.
His nerve broke, and with a cry he flew up and over the trunk, leaving his friends behind. I'm sorry! Pumping his wings, he darted through the trees, over the bushes, and emerged out into a clearing. The sounds of his friend's cries were fading behind him, dwindling to nothing the further he flew.
A shadow passed over him.
Gasping, Petrie spun around and jerked his head up, frantically scanning the air. In the darkness of the night sky, he couldn't see anything... then a large shape passed over the moon. Razor-sharp talons, glinting teeth... hurtling down towards him. With a scream, Petrie desperately tried to speed up. There was a predatory hiss, and with a jolt of pain he was snatched out of the air, into the flyer's talons.

Still sleeping, Petrie's small frame fluttered down and landed amongst his friends as they formed a circle. A low, dangerous hiss was escaping his beak. Small pops, brutal cracks sounded from his body as, slowly, he started to grow. And change.
