In order to remain airborne, the soarer must glide in a column of air that is rising at a rate exceeding the relative rate of descent of the gliding animal.Ĥ. It is attained by many birds (especially large forms, such as condors and albatrosses) and a few insects (e.g., monarch butterfly). California condor (Gymnogyps californianus) Soaring is sustained gliding without power input. Adaptations for directed gliding serve primarily to enhance the glide ratio (the amount of horizontal distance covered per unit descent) and include winglike modifications of fins (several fish groups), webs between digits (a frog, Rhacophorus several lizards), distensible rib-supported vanes (lizards of the genus Draco several snakes) and a fold of skin between the forelimbs and hind limbs (marsupial gliders colugo sciurid and anomalurid flying squirrels). Gravitational gliding may be directed, in which case the animal launches itself toward a definite target or passive (parachuting), in which case the organism slows its descent, relying on wind for horizontal motion. Gliding flight may be of two types: gravitational gliding and soaring. The advantages conferred by flight are also great: in terms of numbers of species as well as numbers of individuals, insects, birds and bats are among the most successful animal groups. Similar modifications in insects have occurred through different evolutionary pathways. The evolutionary modifications necessary for true flight in warm-blooded animals include those of the forelimbs into wings lightening and fusion of bones shortening of the torso enlargement of the heart and thoracic muscles and improved vision. Winged (true) flight is found only in insects (most orders), most birds and bats. in animals, locomotion of either of two basic typespowered or true, flight and gliding.
