This footage is quite amazing. Even those with little interest of wildlife will find it fascinating. The aggressor is less than a year old and it inflicts serious damage on its opponent who just happens to be its father. The claws it uses to attack the pinned down father are its primary weapon and this is no play fight. Those claws are deadly; they are what buzzards use to kill prey.
What must the poor father buzzard be thinking as he is attacked by his chick with such ferocity? He was a good father too and has in previous years reared many generations of new buzzards. Last year I would often watch as he delivered food up to the nest for this vicious little horror - and this is the thanks he gets! I thought if there was food a plenty for all, this type of situation would not occur, but obviously I was wrong.
