Sonic swinging pigeons ( Leptotila ) are a genus of pigeon birds . It includes eleven species whose range extends from northern Mexico to Bolivia and Uruguay.
Appearance
Sonic swing pigeons reach a body length between 25 and 31 centimeters. Thus they correspond to the body size of a laughing pigeon to that of a smaller city pigeon. Long and featherless legs are characteristic of the species. They are ground-dwelling species whose plumage is usually gray to brown. They all have a red-brown coat and red-brown undersides of the wings. The tail is short in relation to body size and has ten feathers. Apart from the two central tail feathers, all have a white tip. Flying sound pigeons produce a whirring flight noise as an instrumental sound . This noise is similar to the flight noise of the partridge and gives the genus its name. It is generated by an outermost flywheel, narrowed in the last third.
behavior
The food spectrum of the sounding pigeons consists mainly of berries and seeds. The full clutch has two eggs in all species. The shell color is cream to white. Fast and nervous movements of the head and tail are characteristic of this species of pigeon.
Duration
Most species of sounding pigeons are classified as safe by the IUCN . The grenade pigeon is, however, an endangered species. The population is estimated at only 70 to 120 individuals. The population is also fragmented due to habitat loss. There are currently conservation efforts for the species aimed at having at least 600 individuals in self-sustaining subpopulations in the wild.
The Tolima pigeon , which occurs in the central Andes of Colombia at altitudes between 1,800 meters and 2,500 meters, is classified as critically endangered by the IUCN. The range of this species is very small and is also subject to human intervention, which leads to habitat fragmentation . The brown-backed pigeon and the yellow-bellied pigeon are considered endangered.
