Here we have a bird called called a "Magpie", which is not like
european or american "magpies" except that its balck-and-white.
Otherwise its like a small crow (even related to them) and during
mating season they are a major problem as they defend their nests by
violent divebombing attacks. Dozens of people lose eyes every year to
magpies! The police go round shooting the really bad ones. Anyway,
the point it the females are most likely to divebomb, so maybe the
attacking raven was female....
