Large ravens can weigh 2 kg (4.4 lb), attain a 1.5 m (4.9 ft) wingspan and measure 0.8 m (2.6 ft) long.[71] The closest non-corvid contender to largest size is the Australian superb lyrebird (Menura novaehollandiae), which can reach a length of 1 m (3.3 ft), much of it comprised by their spectacular tail, and a weight of 1 kg (2.2 lb).[72] The largest species in the most species-rich passerine family, Tyrannidae or tyrant-flycatchers, is the great shrike-tyrant of the South Andes (Agriornis lividus), at 99.2 g (3.50 oz) and 31 cm (12 in), although the fork-tailed flycatcher (Tyrannus savana), to 41 cm (16 in), is longer thanks to its extreme tail.[11][73] The namesake of the previous family, the Old World flycatchers, reaches its maximum size in the green cochoa of Southeast Asia (Cochoa viridis), if it is indeed a proper member of the family, at up to 122 g (4.3 oz)[11] and a length of 29 cm (11 in).
