I agree that a gopher is a rather large prey for a Ardea herodias. However
it's very close european relative Ardea cinerea will happily eat just about
anything it can kill and swallow. Mammalian prey includes mice, water-voles
(which are largish, up to ca 200 mm), field-voles, water-shrews and even
moles! They can be really serious predators on Little Grebes.
