Red-footed Falcon

About

The Red-footed Falcon is a small, elegant raptor belonging to the falcon family. It is known for its distinctive reddish-orange legs and cere, and marked sexual dimorphism in plumage. This species is highly migratory, breeding across Eastern Europe and Asia and wintering in Africa. It is primarily an insectivorous falcon, often hunting in groups.

Size & lifespan

Length

28-34 cm (11-13 in)

Wingspan

65-76 cm (26-30 in)

130-197 g (4.6-6.9 oz) for males, 136-200 g (4.8-7.1 oz) for females

Lifespan

Typically 5-8 years in the wild, up to 13 years recorded

Diet

Carnivore (primarily insectivorous, especially large insects like grasshoppers, crickets, beetles, dragonflies; also small mammals, birds, and amphibians)

Physical characteristics

Plumage

Adult males are uniformly dark slate-grey with chestnut-red undertail coverts and 'trousers' (thighs). Adult females have a rufous-orange head and underparts, grey upperparts with dark barring, and a distinctive dark 'mask' around the eye. Juveniles are brown above with pale streaking, buffy underparts with dark streaking, and a dark eye-stripe.

Beak shape

Short, hooked beak, typically greyish-blue with a yellow cere.

Eye color

Dark brown, surrounded by a reddish-orange eye-ring in adults.

Leg color

Bright reddish-orange in adults, duller orange-yellow in juveniles.

Distinguishing features

Adult males are unmistakable with their uniform dark grey plumage and red legs/cere. Adult females are distinguished by their rufous head and underparts, grey back, and dark eye-mask. The reddish-orange legs and cere are key identifiers for all adults.

Juvenile appearance

Juveniles are duller than adults. They have brown upperparts with pale feather fringes, buffy underparts with heavy dark streaking, and a prominent dark eye-stripe. Their cere and legs are duller orange-yellow.

Seasonal changes

No significant seasonal plumage changes in adults, beyond wear and tear. Juveniles gradually acquire adult plumage over their first year.

Sexual dimorphism

Pronounced. Males are dark slate-grey with chestnut undertail coverts and thighs. Females have a rufous head and underparts, grey barred upperparts, and a dark eye-mask.

How to identify

1. 1

   Size and Shape

   Small, slender falcon with relatively long wings and tail. Appears elegant in flight.

2. 2

   Adult Male Plumage

   Unmistakable: uniform dark slate-grey body, wings, and head, with contrasting chestnut-red undertail coverts and 'trousers' (thighs). Red legs and cere.

3. 3

   Adult Female Plumage

   Rufous-orange head and underparts, grey upperparts with dark barring, and a distinct dark 'mask' around the eye. Red legs and cere.

4. 4

   Juvenile Plumage

   Brown upperparts with pale streaking, buffy underparts with dark streaking, and a dark eye-stripe. Dull orange-yellow legs and cere.

5. 5

   Legs and Cere Color

   Bright reddish-orange in adults, duller orange-yellow in juveniles. This is a key field mark.

6. 6

   Flight Style

   Buoyant and agile, often hovering like a Kestrel, but also capable of swift, direct flight and soaring. Often hunts in groups.

7. 7

   Habitat

   Look for them in open grasslands, steppes, and agricultural areas with scattered trees.

Habitat & range

Biomes

Temperate grasslands, steppes, agricultural areas, open woodlands, river valleys, and forest edges.

Geographic range

Breeds from Eastern Europe (e.g., Hungary, Romania, Ukraine, Russia) eastward across the steppes of Central Asia to Mongolia and northern China. Winters primarily in southern and eastern Africa, from Angola and Namibia east to South Africa.

Elevation range

Typically found in lowlands and plains, up to around 1,500 meters (4,900 feet) during breeding, but generally avoids high altitudes.

Preferred environments

Open country with scattered trees or small groves, often near water bodies. They favor areas with abundant large insects and suitable nesting sites, such as old rookeries or tree cavities.

Behavior

Activity time

Diurnal, most active during daylight hours, particularly in the morning and late afternoon for hunting.

Feeding habits

Primarily insectivorous, often hunting in flight by hawking insects or by perching and swooping. They are adept at catching insects on the wing or from the ground. They also hover frequently, similar to Kestrels, to spot prey. During migration and in wintering grounds, they can form large feeding flocks, especially around insect outbreaks.

Social behavior

Highly social, especially during migration and in wintering grounds, where they can form large communal roosts and feeding flocks of hundreds or even thousands of individuals. During the breeding season, they nest colonially, often in old rookeries of Rooks or other corvids.

Flight pattern

Graceful and agile flight, often characterized by buoyant, buoyant wingbeats and frequent hovering. They can be seen soaring on thermals or gliding. When hunting, they exhibit rapid pursuit and agile maneuvers.

Migration pattern

Long-distance migratory. They breed in Eurasia and undertake a significant migration to winter in southern Africa. Migration occurs in large flocks, often following specific flyways. Autumn migration is typically from August to October, and spring migration from March to May.

Territoriality

While they nest colonially, individual pairs defend a small area immediately around their nest. Feeding territories are less strictly defined, especially when hunting in groups.

Breeding & reproduction

Breeding season

May to July, with egg-laying typically in late May to early June.

Nesting habits

Does not build its own nest. Primarily uses old nests of other birds, especially Rooks (Corvus frugilegus), but also Hooded Crows (Corvus cornix) or Magpies (Pica pica). Nests are typically in trees, often in loose colonies.

Clutch size

3-5 eggs (range 2-6)

Egg description

Typically 3-5 eggs, sometimes 2-6. Eggs are pale creamy-white to yellowish-white, often unmarked or with very faint reddish-brown speckles.

Incubation period

22-28 days, primarily by the female, though the male may assist.

Fledging period

27-30 days after hatching. Young leave the nest but remain dependent on parents for a further 1-2 weeks.

Parental care

Both parents participate in incubation and feeding of the young. The male typically provides food for the female during incubation and for the chicks after hatching, with the female doing most of the direct feeding.

Where to find

Field tips

1. Look for communal roosts. During migration and in wintering grounds, Red-footed Falcons often gather in large numbers at communal roosts, typically in trees. These can be spectacular to observe.
2. Observe hunting behavior. Watch for their characteristic hovering flight over open fields, followed by a dive to catch insects. They often hunt in groups, which can be a good indicator.
3. Check old corvid nests. In breeding areas, scan old rookeries or other large tree nests, as Red-footed Falcons do not build their own nests.
4. Focus on leg and cere color. The reddish-orange legs and cere are a crucial identification feature, especially for distinguishing from similar species like Amur Falcon.

Fun facts

• Red-footed Falcons are one of the few raptor species that regularly hunt in large groups, especially during insect outbreaks.
• They are known to follow agricultural machinery to catch insects disturbed by the activity.
• Their reliance on old corvid nests means their breeding success can be linked to the health of corvid populations in their breeding range.
• The species was formerly considered conspecific with the Amur Falcon (Falco amurensis), but they are now recognized as distinct species based on genetic and morphological differences.
