灰穴(共鳥)

The cinereous tinamou (Crypturellus cinereus) is a ground-dwelling bird in the family Tinamidae, found across lowland Amazonia in South America, including Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, and the Guianas. It inhabits humid tropical forest interior, particularly terra firme and occasionally várzea, where it walks through the undergrowth foraging for fallen fruits, seeds, and invertebrates. Like all tinamous, it has a round body, reduced wings, and strong legs adapted for a largely terrestrial lifestyle, and it produces a distinctive haunting whistle heard throughout Amazonian forest. The cinereous tinamou is classified as Least Concern by the IUCN, with a wide Amazonian distribution and populations that, while sensitive to hunting pressure, remain abundant in intact forest. Tinamous are among the most ancient lineages of birds, more closely related to rheas and ostriches than to most modern birds. This species is hunted for food by forest communities across its range. Its distribution is entirely within Amazonian South America, and it has no presence in Europe; any Norwegian database record is a data entry error. Conservation of Amazonian forest is the primary need for this species, as it is vulnerable to hunting pressure and habitat loss from deforestation. Males incubate the eggs and raise the chicks, a pattern unusual among birds.
