Re: Bird behavior, vision
A photographer at Blackwater refuge in Maryland (Eastern Shore)
captured a series of photographs of Ardea herodias capturing and
swallowing a subadult muskrat somewhat larger (qualitatively) than the
gopher. Rare as well, of course, but at least one other example of a
similar predation event.

Go here for a series of amazing photos of a heron capturing a gopher.
I'm not accustomed to seeing herons hunt rodents, much less rodents of
unusual size! Also, check out the way the prey has been speared .
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.
