The imitative sounds of talking birds have little in common with human
language, but the natural calls and songs of many species of birds do have a
communicative function. They also resemble human languages in that there are
“regional dialects” within the same species, and as with humans, these dialects
are transmitted from parents to offspring. Indeed, researchers have noted that
dialect differences may be better preserved in songbirds than in humans because
there is no homogenization of regional accents due to radio or TV.
