The Eurasian buzzard has a monogamous mating system, with the pair bond usually lasting for life. The breeding season takes place from late March through May. The male will first perform spectacular display flights to attract a mate or to strengthen the bond between the pair and to mark the territory. If the male already has a mate, the female will also perform display flights.

The female determines the nesting site and is responsible for building the nest. The male will supply materials to build the nest. The nest consists of a voluminous, sturdy platform of dead branches and twigs. The female will line the inside of the nest with finer material. The nest is often located on a branch or in a fork of a large tree, usually close to the edge of the forest.

The breeding season mainly starts in April and May, during which the female remains on the nest even if there are no eggs yet. During this period, the male provides food for the female and is crucial for the quality of the eggs. When the female wants to mate, she invites the male into the nest (or its immediate vicinity) for the mating ritual.

The clutch usually consists of 2 to 4 eggs. The female incubates the eggs for a period of 33 to 38 days per egg. The male provides her with food during this time. After hatching, the young remain in the nest for about 3 weeks. Afterwards, the young fly out and are cared for by their parents for another 6 to 8 weeks.
