Crow attacks Sparrowhawk nest at Royal Botanic Garden Edinburgh

This video shows a crow attack the female sparrowhawk who was guarding the eggs. Unfortunately, it is unlikely the sparrowhawk survived; the eggs certainly didn't.
Background info:
In a successful parternship with RSPB, the Royal Botanic Garden Edinburgh had cameras looking directly at the nest of a pair of Sparrowhawks nesting in the garden. The sparrowhawks had recently laid five eggs.
