Is there a pattern/tactics of behavior in any birds species that consists of attacking a predator's eyes with its beak?
I'm looking for established tactics, not 1 or 2 anecdotal examples.

From this paper about black-headed gulls responding to a hedgehog:
The gull might peck the intruder, or strike it with its feet. Pecks were mostly directed at the hedgehog's head and might be delivered after a horizontal approach with the wings partly lifted.
Although not directed at the eyes specifically, they observed the birds directing attacks to the predator's head.
There's another paper (Ratner 1975) that also looks promising, but I'm on my home computer and can't access it right now
