Hoatzin nestlings have unique adaptations, such as wing claws, enabling them to climb back to their nests. Despite these traits being found in other birds, the Hoatzin remains an evolutionary enigma, being the only species in its order. Its evolutionary history is unclear, with debates on its closest relatives. The Hoatzin's distinctiveness highlights the diversity and complexity of avian evolution.
