An opportunistic and versatile predator, the lesser spotted eagle feeds upon a variety of mammals, birds, reptiles, amphibians, and insects. Its major source of prey varies according to location, with populations in humid lowlands consuming large numbers of amphibians, while those in hills and mountains are more reliant on mammals. At the wintering grounds, this species commonly consumes nestlings of the red-billed quelea (Quelea quelea), along with swarms of alate termites. Three hunting techniques are employed by the lesser spotted eagle: soaring at around 100 metres before diving down; swopping down from a perch; and walking along the ground (4).
Breeding populations of the lesser spotted eagle in central Europe commence egg laying in late April and early May. The birds build a large platform of twigs, usually high up in a tree, but on rare occasions on the ground, with a central nest cup, around 30 centimetres wide, lined with green twigs and sometimes with grass. A clutch of two eggs is normally laid, which are incubated for 36 to 41 days. During the following eight-week fledging period, the older chick frequently kills its younger sibling. Sexual maturity is not reached until three to four years old and the lifespan is believed to be 26 years (4).
