How do you draw a hoatzin?

To draw a hoatzin, start by sketching its distinctive body shape, which is stocky with a long tail. Focus on its unique features, such as the spiky crest on its head and its large, bright blue facial skin. Add details like its long, clawed fingers and the pattern of its feathers, which are generally brown with lighter streaks. Finally, refine your lines and add color to capture the hoatzin's vibrant appearance.
