The three brush tail species we see the most on the Antarctic Peninsula are
Chinstrap, Adelie and Gentoo.
Of the three, the Adelie is the shortest.
This picture is amazing as it not only captures all three in one place at the same time,
which is sort of uncommon,
but also because each is displaying its own personality, unique to the species.
They move and act differently, subtle differences for sure, but there nonetheless.
