Penguin (Eudyptula minor)
The world's smallest penguin
averages only 12 inches in height, with an
average weight of 2.5 pounds, hence the common
name "Little Penguin." It is white from
the chin down the belly and on the underside of
the flippers, and indigo blue everywhere else,
hence its alternate names of "Little

As its name suggests, this penguin
is distinguished by its yellow eyes, along with a
bright yellow band encircling the head from eye

penguins do not nest within sight of each other.
The Adélie Penguin
sports a characteristic "tuxedo look,"
with a blue-black back and completely white chest
and belly. It is one of only two penguins found
on the Antarctic mainland, the other being the
The Gentoo Penguin (Pygoscelis
is distinguished from other penguins by two white
wedges behind the eyes that are connected by a
medium-sized line across the top of the head, as
well as a bright dark-orange lower mandible. It
also has the most prominent tail of all penguins.
is endemic to the subtropical Pacific coasts of
Chile and Peru, adjacent to the Humboldt Current.
It is distinguished from the Magellanic Penguin
by a wide, solid black breast band, which also
helps in distinguishing adults from juveniles.
This penguin is most easily identified by the
white bands which loop over the eye, down the
side of the neck and meet at the throat. It
breeds around the southern tip of South America,
from 40°S in Argentina to 37°S in Chile, as
well as on the Falkland Islands.
