Cinereous Vulture
Aegypius monachus
The cinereous vulture measures 98–120 cm (39–47 in) in total length with a 2.5–3.1 m (8 ft 2 in – 10 ft 2 in) wingspan. Males can weigh from 6.3 to 11.5 kg (14 to 25 lb), whereas females can weigh from 7.5 to 14 kg (17 to 31 lb). It is the largest accipitrid and is thus one of the world's heaviest flying birds. Average weights were long not known to have been published for this species but the median weight figures from two sources were 9.42 kg (20.8 lb) and 9.55 kg (21.1 lb). However in a Korean study, a large survey of wild cinereous vultures was found to have weighed an average of 9.

Swamp Harrier
Circus approximans
The swamp harrier is largely dark brown, becoming lighter with age, and has a distinct white rump. It hunts by flying slowly, low to the ground, on upswept wings. The body length is 48 to 62 cm (19 to 24.5 in), and the wingspan is 118 to 145 cm (3 ft 10 in to 4 ft 9 in). The recorded weights of adults range from 580 to 1,100 g (1.28 to 2.43 lb). Females are significantly larger than the males. In New Zealand, 54 males averaged 640 g (1.41 lb) and 66 females averaged 870 g (1.92 lb).
