From the natural selection angle, for a Buteo hawk to land on an
Eagle's nest in the Eagle's presence is worthy of a Darwin Award.
More than twenty years ago, we were at the You Yangs in September.
We watched fascinated as a pair of Peregrines chased each other round
the hill-tops in courting flight, with acrobatics thrown in. A Brown
Falcon got up in the air - perhaps to make its own territorial claim. A
serious error - one of the Peregrines dived at it. The Brown tried
evasive action but the Peregrine struck it on the back. The talons were
not extended - what the Brown got was a passing biff with the knuckles
of the foot. The Brown retired very hastily to a wattle-tree in great
disorder. It then moved lower in the wattle, apparently winded and
severely frightened, with its plumage very ruffled.
When I first saw the falcons, I had scuttled up a fairly high rock
and the collision took place quite close to my eye-level, over steeply
sloping ground, so I had an excellent view. I am certain that if the
Peregrine had struck the Brown with its claws open, the Brown would have
been killed.

Hi birding-aus,
Not sure if anyone has ever seen a White-bellied Sea-Eagle doing what its North
American cousin, a Bald Eagle, is doing here:
Eagle-cam in New Jersey, US.

Note: This footage contains some avian violence.
Cheers,
