Nankeen Kestrel

The Nankeen Kestrel is a familiar sight across open Australian countryside, often seen hovering over roadsides, farmland, and grassland while scanning for prey. Its name references the pale tan-buff 'nankeen' cloth color that closely matches its back plumage. It is closely related to the widespread Common Kestrel of Eurasia and Africa, sharing a similar hovering hunting technique.

Feathers are commonly found near roadside perches, fence posts, and open paddocks throughout its range.

Recognizing Nankeen Kestrel feathers

• Flight feathers: Rufous-tan above with dark barring toward the tips, moderately pointed.
• Tail feathers: Pale grey in males with a black subterminal band; more barred rufous-brown in females.
• Body feathers: Back feathers warm rufous-tan (nankeen); underside feathers whitish to buff with light dark spotting, sparser than many other kestrels; male head feathers pale grey.
• Shaft color: Pale tan to grey.
• Compared to similar species: Smaller and paler overall than the Brown Falcon; the pale grey male tail feather with a single black band is diagnostic compared to the more barred tail of most other Australian falcons.

Adult males have a pale grey head, rufous-tan back with sparse dark spotting, and a pale grey tail with a broad black subterminal band; underparts are whitish with light spotting. Females are more uniformly rufous-brown above with more barring, including on the tail. Juveniles resemble females, with young males gradually acquiring the grey head and tail through molt.

Widespread across Australia in open grassland, farmland, roadside verges, and semi-arid country, and has also colonized New Zealand. Largely resident, though some populations move nomadically or seasonally in response to prey availability.

Well known for hovering in place while scanning the ground below, then dropping onto small mammals, insects, and reptiles. Nests in tree hollows, cliff ledges, or old stick nests, and readily uses artificial structures. Calls are shrill, repeated chattering notes. A rufous-tan back feather alongside a pale grey, black-banded tail feather found near open farmland in Australia is a strong indicator of an adult male Nankeen Kestrel.
