Habitat: Tinamous inhabit dense tropical forests, including humid lowland rainforests, montane forests, and forest edges from coast to 1500 m. They are typically found in areas with thick vegetation where they can forage for fruits, seeds, insects, and small animals on the forest floor.
Behavior: These birds are known for their secretive nature and are often heard more than seen due to their shy behavior. Great Tinamous are primarily terrestrial, spending most of their time foraging on the forest floor. They are skilled runners and can move swiftly through the undergrowth to escape predators.
Breeding: Great Tinamous are monogamous and form pairs during the breeding season. The female typically constructs a well-hidden nest on the ground, where she lays a clutch of 2-4 eggs. Both parents take turns incubating the eggs, which hatch after about three weeks. The chicks are precocial, meaning they are born in an advanced state and are able to move around shortly after hatching.
Conservation Status: The Great Tinamou is classified as a species of "Near Threatened Concern" on the IUCN Red List.
