Kerrtinamu

The Choco Tinamou (Crypturellus kerriae) is a ground-dwelling bird in the family Tinamidae, one of the most ancient lineages of birds, endemic to the humid lowland and foothill forests of the Chocó biogeographic region, occurring in western Colombia and just extending into eastern Panama. Tinamous are secretive, largely terrestrial birds related to ratites despite their ability to fly, and are known for their extraordinarily beautiful, haunting calls — rich, melodic whistles or flute-like notes that echo through forest interiors at dawn and dusk. The Choco Tinamou inhabits the floor and lower understorey of humid tropical forest, where it forages for fallen fruits, seeds, invertebrates, and fungi. Like other Crypturellus tinamous, it is very difficult to observe directly in the dense undergrowth but may be detected reliably by voice. Nesting is unusual among tinamous: males incubate eggs and care for chicks while females may mate polygamously with multiple males. The IUCN classifies the Choco Tinamou as Vulnerable, reflecting severe ongoing deforestation in the Colombian Pacific lowlands for cattle ranching, palm oil, logging, and human settlement, which has drastically reduced and fragmented its forest habitat.

Grautinamu

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.
