Greta oto is a species of brush-footed butterfly and member of the subfamily Danainae, tribe Ithomiini, and subtribe Godyridina.It is known by the common name glasswing butterfly for its transparent wings, which allow it to camouflage without extensive coloration.
Bird Image Species Family Maximum height Details Rüppell's vulture: Gyps rueppellii: Accipitridae: 11,300 metres (37,100 feet). [1] [2] Vultures use their excellent eyesight to scan the landscape below from a relatively static aerial position. Instead of flying over a larger distance, they use elevation to expand their field of vision. [3]
Hemaris thysbe, the hummingbird clearwing, is a moth of the family Sphingidae (hawkmoths). Coloration varies between individuals, but typically the moth is olive green and burgundy on its back, and white or yellow and burgundy on the underside.

Bird–window collisions (also known as bird strikes after the aviation term or as window strikes) are a problem in both low- and high-density areas worldwide. Birds strike glass because reflective or transparent glass is often invisible to them. [ 1 ]
The magnificent frigatebird (Fregata magnificens), frigate petrel [2] or man o' war [3] is a seabird of the frigatebird family Fregatidae.With a length of 89–114 centimetres (2 ft 11 in – 3 ft 9 in) and wingspan of 2.17–2.44 m (7 ft 1 in – 8 ft 0 in), it is the largest species of frigatebird.
The smallest flying vertebrates are the bee hummingbird and the bumblebee bat, both of which may weigh less than 2 grams (0.071 oz). They are thought to represent the lower size limit for endotherm flight. [citation needed] The smallest flying invertebrate is a fairyfly wasp species, Kikiki huna, at 0.15 mm (0.0059 in) (150 μm). [23] Fastest.
Lesser flamingos flying in formation. When in gliding flight, the upward aerodynamic force is equal to the weight.In gliding flight, no propulsion is used; the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird, resulting in a descending flight, or is replaced by rising air currents ("thermals"), referred to as soaring flight.
