Falco femoralis

Large336 gGrassland

The aplomado falcon is very slender, long-winged, and long-tailed, the size of a small peregrine falcon (F. peregrinus), at 30–40 cm (12–16 in) long and with an average wingspan of about 90 cm (35 in), but only half the weight, at about 208–305 g (7.3–10.8 oz) in males and 270–460 g (9.5–16.2 oz) in females. In adult birds, the upperparts are dark blue-grey, as is much of the head, with the usual falcon "moustache" contrasting sharply with the white throat and eyestripe.
