Everything about Pica Genus totally explained
Pica is the
genus of three
species of
birds in the family
Corvidae in both the
New World and the
old. They have long tails and have predominantly black and white markings. One species ranges widely from
Europe through
Asia, one occurs all over
North America and the third is restricted to
California. They are usually considered closely related to the blue and green
magpies of Asia, but recent research (Ericson
et al., 2005) suggests their closest relatives are instead the
Eurasian
crows.
Two or three species were generally recognized, the Yellow-billed and one or two black-billed ones. Recent research has cast doubt on the taxonomy of the
Pica magpies (Lee
et al., 2003).
P. hudsonia and
P. nuttalli are each other's closest relatives, but may not be different species. If they are, however, at least the
Korean race of
P. pica would have to be considered a separate species, too.
