Peregrine Falcon: where and when to see them

The peregrine falcon is a powerful bird-hunting raptor found on every continent except Antarctica. Long pointed wings, a dark facial moustache and rapid flight make it distinctive when seen well. Coastal cliffs remain classic habitat, but tall buildings and bridges can imitate natural nesting ledges. Following severe twentieth-century pesticide declines, many populations recovered through protection and reduced chemical exposure, although disturbance, persecution and other regional threats have not disappeared.

Peregrines hunt from elevated perches or while flying, sometimes climbing before a steep, controlled attack. They also pursue birds horizontally rather than relying exclusively on spectacular high-speed stoops. Pairs occupy territories and use simple nesting scrapes on ledges, with both adults contributing to parental care. Females are larger than males and often take larger prey. Northern populations may migrate long distances, while many temperate coastal pairs remain near their territories. Peregrines are renowned for their 'stoop,' a high-speed dive that can exceed 200 mph, used to strike prey mid-air. Pair bonds are generally strong and mates often return to the same nest site year after year.

• Females are substantially larger than males.
• The nest is usually a shallow scrape rather than a stick structure.
• Its scientific name refers to wandering or travelling.
• A small projection inside each nostril is associated with managing airflow during fast flight.

Resident pairs can be observed throughout the year in parts of all three destinations. New England's autumn coastal migration is particularly useful for distant flight observation. Mediterranean spring weather favours coastal watching, but breeding cliffs require extra restraint and compliance with seasonal closures. In Croatia and Greece, wintering birds can be seen along the coast, often supplementing resident populations. Early morning or late afternoon often provide the best light for distant observations and reveal hunting activity.

Sea cliffs, mountain crags, river gorges and tall urban structures provide nesting and lookout sites. Productive hunting areas include coasts, estuaries, wetlands and open country with abundant birds. Migrants can appear far from established breeding territories, especially along coastlines. In coastal areas, nesting sites can include remote islands or steep sea stacks. Their adaptability to urban environments highlights their ability to coexist with human infrastructure when prey is abundant.

Birds dominate the diet, ranging from small songbirds to pigeons, shorebirds and ducks according to local opportunities. Most prey is captured in flight, though other hunting methods occur. Urban pairs often exploit pigeons, while coastal birds may rely heavily on seabirds or waders. Remarkably, over 450 bird species have been recorded as peregrine prey worldwide, showcasing their opportunistic hunting. During migration, they may also occasionally take insects or small mammals if birds are scarce.

Identification

A robust body, pointed wings and broad dark moustache distinguish it from the smaller, slimmer hobby and the longer-tailed, more frequently hovering kestrels. Juveniles display brownish upperparts with streaked underparts, contrasting with the adult's slate-blue back. Their powerful, deep wing beats are distinctive in flight, especially when covering long distances.
