157155 Peregrine - Falco peregrinus. W 95-115cm. One of our most impressive raptors. Soars on broad, bowed wings but stoops with wings swept back at phenomenal speed on prey such as pigeons. Sexes are similar but male is smaller than female. Adult has dark blue-grey upperparts and pale, barred underparts. Note dark mask on face and powerful, yellow legs and feet. In flight from above, looks uniformly dark grey although rump may appear paler; from below, pale underparts are barred and contrast between pale cheeks and throat, and dark moustache, is striking. Juvenile is similar to adult but upperparts are brownish while paler underparts are suffused with buffish orange. Voice Utters a loud kek-kek-kek… in alarm. Status Widespread resident in N and W Britain and Ireland. Population is recovering following crash caused by pesticide contamination in 1960s. Favours mountains and coastal cliffs but increasingly nests in towns and cities.
