"Has anyone done DNA testing on American and Northwestern Crows? I'm willing to
bet that's the only way we'll really be able to tell if they are truly two
different species."

the problem with the method of speciating crows (or anything else,
for that matter) using DNA analyses is defining exactly how similar
or different two species must be before they are classified as
separate species.
