Possibly all of the above. "Cartwheeling" between male
White-bellied Sea-eagles (as shown in the video "Eagle", and
probably "Life of Birds") is a form of ritual combat used in
territorial disputes, but I have also seen talon grappling
between male and female Little Eagles (see below.)

I have seen this display between two Little Eagles at Googong Dam
outside of Queanbeyan NSW. One bird was gliding more or less
horizontally, then a spotted the second bird diving down at an
angle of approximately 30 degrees from behind it. (The size
difference between the birds suggested male and female - I forget
which bird was which now.) When the birds were about to "collide",
the lower bird flipped upside down, briefly locked talons and then
continued on its way; there was no food exchanged. My initial
impression was that it may have been a territorial dispute (I have
seen similar encounters between different species of raptors, and
once a Brown Goshawk and Pied Currawong, where a brief flip and
lunge with the talons was used in self-defence), but the slow speed
and "casualness" of this encounter suggested a courtship display.
