Habitat Comparison
Common Kestrel
Open country including farmland, grasslands, moorland, and urban areas. Common along motorways and in cities across Europe.
Shoebill
Freshwater swamps dominated by papyrus and other dense aquatic vegetation in tropical East Africa.
Song & Call Comparison
Common Kestrel
A shrill, repeated 'kee-kee-kee-kee' or 'kik-ik-ik', especially near nest. Alarm call is a nasal chattering. Generally less vocal than larger falcons. Calls ring clearly in open country.
Shoebill
Largely silent; produces mechanical bill-clattering 'clap-clap-clap' when greeting at the nest — similar to White Stork. Also gives low croaking grunts. Rarely calls in the wild.
Geographic Range & Migration
Common Kestrel
Europe, Asia, and Africa. One of the most common and widespread raptors in the Old World.

About These Birds
Common Kestrel
The common kestrel is Europe's most abundant falcon, famous for its ability to hover motionless in the wind while scanning for prey. Research has shown kestrels can see ultraviolet light, allowing them to detect vole urine trails that reflect UV. The species has adapted remarkably well to urban environments.
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
