Spotted Kestrel

The Spotted Kestrel is found across Java, Bali, and other Indonesian islands, occupying open grassland, farmland, and lightly wooded country. As a tropical resident relative of the widespread Common Kestrel, it shares a similar overall look but is generally non-migratory, remaining in place year-round.

Feathers found in open habitat across its Indonesian range showing bold spotting on a rufous back are consistent with this species.

IUCN status: Least Concern, being fairly common within its island range.

Recognizing Spotted Kestrel feathers

• Flight feathers: Rufous-brown above with dark barring, similar in shape to other kestrels.
• Tail feathers: Grey in males with a black subterminal band; rufous and barred in females.
• Body feathers: Back feathers rufous with bold, well-defined dark spotting; underparts feathers pale buff to whitish with dark spotting, often bolder and more distinct than in the Common Kestrel.
• Shaft color: Pale brown to grey.
• Compared to similar species: Closely resembles the Common Kestrel but is generally resident rather than migratory and restricted to Indonesian islands, making range a useful distinguishing factor alongside typically bolder underside spotting.

Adult males show a grey head, rufous back with bold dark spotting, and a grey tail with a black subterminal band; underparts pale with dark spotting. Females are more uniformly rufous-brown with barring above. Juveniles resemble females, with young males developing the grey head and tail with maturity.

Found on Java, Bali, and other Indonesian islands, favoring open grassland, farmland, and lightly wooded country, sometimes into urban edges. Resident, without regular migration.

Hunts insects, small reptiles, and rodents, often hovering over open ground before dropping onto prey. Nests in tree cavities, cliff ledges, or on buildings. Calls include shrill, repeated chattering notes typical of kestrels. A rufous feather with bold dark spotting, found in open grassland or farmland on Java, Bali, or nearby islands, is a good match for this species.
