Looping has been recorded in display. The nest is usually built in trees, 20-50 feet up, and is a solid structure of sticks about three to four feet across and two feet deep, lined with sprigs of pine or green leaves. Where trees are scarce, crags may be used. It is used year after year, and a pair may have more than one nest. Two eggs are normally laid, sometimes one, at intervals of several days.
Incubation begins with the first egg - the female only sitting.
There is considerable difference in size in the young, and only one usually survives. The male brings food to the nest site during both the incubation period and the fledging period. The young are out of the nest by early August, indicating a total breeding time from eggs to fledging of about three months. The young accompany their parents in the territory for some time after making their first flight. Flying demonstrations noon, 2pm and 3.30pm.
