Crows, known as corvus, are part of a diverse
group of more than 120 bird species known as corvids, which
include rooks, ravens, magpies and jackdaws. Corvids have the largest
brain-to-body-size ratios of all birds, with crows in particular being
incredibly intelligent; the journal Current Biology states "the crow brain
is the same relative size as the chimpanzee brain."
Centuries of folklore have painted crows as thieves, tricksters, problem
solvers, advisors to gods or even deities themselves!
In modern times, these birds are more misunderstood, having been
stereotyped as troublemakers, scavengers or noisy pests.
