Physical description Click here for a physical description Booted Eagles are medium-sized raptors, but small eagles. The sexes are alike, although females are both larger and heavier than males. Their plumage comes in two different morphologies, pale and dark. Dark morph Booted Eagles are brown with lighter streaking all over their undersides. The head is solid brown, with a light-brown cap. Also the legs are lighter brown than the rest of the front. The upperside again is mostly dark-brown; lighter outer edges give the wings a scalloped appearance. The front side of the underwings is also brown, separated from the trailing side, which is dark-grey to black with a lighter grey wing panel, by a black underwing bar. In the feathers of the trailing half of the underwings some barring can usually be seen. The pale morphology instead has an off-white front, including everything from chest to undertail coverts and legs, with some brown streaking down the chest. Also the front of the underwings is off-white, with brown spots, while the trailing side is black. The wing panels are dark-grey and barely visible. The upperparts are mostly dark-brown, with broad buff wing bars and faintly visible wing panels. Also the rump is buff. The upperwings are primarily dark-brown with paler wing patches on the coverts. The head is brown, with lighter supercilia. Both morphs have eyes with orange-brown irises, a grey hooked bill with yellow cere and a yellow gape. The feet are yellow, with dark-grey talons. Note that Booted Eagles have 6 "fingers" (outer primaries), instead of the usual 5.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Booted Eagle is available HERE . Booted Eagles are a mostly migratory species. The only sedentary populations exist in southern South Africa and on the southern fringes of the Himalayas. Everywhere else they are migratory. Their breeding range extends from the Atlas mountain range in north-western Africa, via parts of south-western, eastern and south-eastern Europe to parts of Asia Minor and into parts of central Asia. Most overwinter in two general areas: Most of the Indian sub-continent and most of sub-Saharan Africa, except the Horn of Africa, the Congo Basin and parts of the southern coastline of western Africa. During their migration the African population avoids the Sahara desert, moving either along the West coast of Africa or through the Middle East and Arabia and south-western Asia. Normally depending on thermals for lift, they avoid long sea voyages, crossing the Mediterranean near Gibraltar, across Sicily and crossing the Red Sea at the Bab-el-Mandeb strait near Aden. The Indian population moves around the western side of the Himalayas to reach its breeding grounds in central Asia. In Europe the Booted Eagle is a breeding migrant. The breeding range extends through the interior of Iberia to southern and central France, plus mostly mountainous regions in Greece, the Balkans, the Carpathian mountains and from eastern Poland into the border region of Bielorussia with Ukraine and eastwards to the Volga. There are known small overwintering populations on parts of the Spanish Mediterranean coastline, on the Balearic islands and the southern coastal fringe of Sicily. During their migration they can be found along the coastal fringe of Iberia, in Sicily and southern Italy and most of south-eastern Europe. Booted Eagles have a preference for hilly or mountainous terrain with forest, usually interspersed with open areas for hunting.

Sightings Click here for sighting information J. Pires reports finding Booted Eagles semi-regularly in the area of Mora, Evora, Portugal, and its surrounds. They are found there not only during the breeding season but, at least on one occasion, in January 2018, also during winter. All sighting and photographic information presented on this page has kindly been contributed by J. Pires.
