 The peregrine falcon has a body length of 34 to 58 cm (13 – 23 in) and a wingspan from 74 to 120 cm (29 – 47 in). The male and female have similar markings and plumage, but as in many birds of prey the peregrine falcon displays marked sexual dimorphism in size, with the female measuring up to 30 % larger than the male. Males weigh 330 to 1,000 g (0.73 – 2.20 lb) and the noticeably larger females weigh 700 to 1,500 g (1.5 – 3.3 lb). In most subspecies, males weigh less than 700 g (1.5 lb) and females weigh more than 800 g (1.8 lb), with cases of females weighing about 50 % more than their male breeding mates not uncommon. The standard linear measurements of peregrines are: the wing chord measures 26.5 – 39 cm (10.4 – 15.4 in), the tail measures 13 – 19 cm (5.1 – 7.5 in) and the tarsus measures 4.5 to 5.6 cm (1.8 to 2.2 in).
