Adults are large and quite uniform dark brown eagles with very broad wings and short tails. Single white "comma" mark at the wrist of the underwing. Similar to the Lesser Spotted Eagle, which is smaller, paler, and more contrasting. Juveniles are more boldly patterned with numerous prominent dirty white spots on the back and upper wings. More tied to forests than Lesser Spotted Eagle, but still near rivers and bogs. Frequents humanmade habitats more often in winter, such as lakes, rubbish dumps, and reservoirs.
