Creatures of FASA

FASA 365 Day 60, Blind Glider. 20 ft 30ft large wing span 20 ft smaller wing span. Like the name implies, they are indeed blind, but do hunt by sonar, sound and heat signatures.
Nesting along the cliffs faces of deep ravines and canyons in the northern countries. They glide on air currents until they hear or sense the heat of its prey. Silently gliding down and literally falling on its victim.
With 2 sets of wings it is a master of aerial acrobatics, but without feathers it doesn’t fly back up onto the cliffs and high rocks. The 1.5ft talons and leathery ends of it wings allow it to climb back up rock faces efficiently. And it knows its own nesting cliff by the smell of its specific urination.
The Blind Glider hibernates in caves during the summer as heat signatures are unable to be sensed with all the heated rocks.
