The lyrebirds are large passerine birds, amongst the largest in the order. They are ground living birds with strong legs and feet and short rounded wings. They are generally poor fliers and rarely take to the air except for periods of downhill gliding. The superb lyrebird is the larger of the two species. Females are 74–84 cm long, and the males are a larger 80–98 cm long—making them the third-largest passerine bird after the thick-billed raven and the common raven. Albert's lyrebird is slightly smaller at a maximum of 90 cm (male) and 84 cm (female) (around 30–35 inches) They have smaller, less spectacular lyrate feathers than the superb lyrebird, but are otherwise similar.
