Knowra Tinamou Tinamou Tinamou is a family of ground-dwelling birds native to Central and South America. Tinamous can fly but usually forage and nest on the ground, and many have distinctive calls.
Palaeognathae : A major bird lineage that includes tinamous and flightless ratites, distinguished by features of the palate. Tinamous belong to this lineage despite retaining the ability to fly.
Bird vocalization : Sounds produced by birds, often through the syrinx, for communication and other functions. Tinamou calls are prominent signals used to communicate across dense vegetation.
Neotropical realm : A biogeographic region encompassing Central America, the Caribbean, and much of South America. This realm contains the habitats and geographic range of all tinamous.
Ostrich : A large, flightless African bird and the largest living bird species. Unlike the flight-capable tinamou, the ostrich is a highly specialized running ratite.
Palaeognath evolution : The evolutionary history and diversification of ratites and tinamous within the palaeognath bird lineage. Tinamous’ ancestry complicates explanations of how flightlessness evolved among palaeognaths.
Ratite : A traditional grouping of mostly flightless birds, including ostriches, emus, and rheas. Their relationship to ratites is central to tinamous’ unusual place in bird evolution.
Syrinx : The vocal organ of birds, located where the trachea divides into the bronchi. The syrinx produces the clear, far-carrying calls characteristic of tinamous.
Tropical rainforest : A warm, high-rainfall forest biome with dense vegetation and high biodiversity. Forest tinamous forage and nest amid the dense understory of these ecosystems.
Rhea : A large, flightless South American bird in the palaeognath lineage. Rheas share the continent and broad lineage with tinamous but are much larger and flightless.
Avian phylogenetics : The study of evolutionary relationships among birds using anatomical and genetic evidence. Genomic studies have revised the inferred relationships among tinamous and ratites.
