[28] Windows can also be covered with decals spaced no more than 5 cm horizontally or 10 cm vertically to prevent collisions. [29] It has been found that silhouettes of predatory birds posted on windows do not significantly decrease collision rates. This is because there is too much exposed glass, which the bird can try to fly through.
Bird strikes happen most often during takeoff or landing, or during low altitude flight. [12] However, bird strikes have also been reported at high altitudes, some as high as 6,000 to 9,000 m (20,000 to 30,000 ft) above the ground. Bar-headed geese have been seen flying as high as 10,175 m (33,383 ft) above sea level.
Bird flight is the primary mode of locomotion used by most bird species in which birds take off and fly. Flight assists birds with feeding, breeding , avoiding predators , and migrating . Bird flight includes multiple types of motion, including hovering, taking off, and landing, involving many complex movements.
A wing-clipped Meyer's parrot perching on a drawer handle. While clipping is endorsed by some avian veterinarians, others oppose it. [7]By restricting flight, wing clipping may help prevent indoor birds from risking injury from ceiling fans or flying into large windows, but no evidence shows that clipped birds are safer than full-winged ones, only that clipped birds are subject to different ...
A window screen (also known as insect screen, bug screen, fly screen, flywire, wire mesh, or window net) is designed to cover the opening of a window. It is usually a mesh made of metal, fibreglass , plastic wire, or other pieces of plastic and stretched in a frame of wood or metal.
Rüppell's vultures commonly fly at altitudes as high as 6,000 m (20,000 ft). [10] The birds have a specialized variant of the hemoglobin alpha D subunit; this protein has a great affinity for oxygen, which allows the species to absorb oxygen efficiently despite the low partial pressure in the upper troposphere .

Robert Todd Carroll (2003), having consulted an entomologist (Doug Yanega), identified rods as images of flying insects recorded over several cycles of wing-beating on video recording devices. The insect captured on image a number of times, while propelling itself forward, gives the illusion of a single elongated rod-like body, with bulges.
Filmed over four years, in six continents and more than 40 countries, the Earthflight team used many extraordinary techniques. For some of the unique flying shots, members of the team became part of the flock. The birds followed wherever they went - even in a microlight over Edinburgh and London. In Africa, paragliders floated alongside wild ...
