Situated on the coast of
Hooker Island
in Franz Josef Land,
Rubini Rock is one of the most abundant habitats for cliff-nesting
birds in the Arctic. Formed of hexagonal columnar basalt, the
rock fractures into niches in which the multitude of birds make
their nests.

Every little speck of white is a bird. Birds of a feather
flock together, and
kittiwakes,
guillemots,
and
little auks
all stake out their own turf (or, more precisely, rocky niche) on the cliff.

Orange and green lichen adorn the rock. The top predator here
is the
glaucous gull
(Larus hyperboreus),
which feeds on the eggs of cliff nesting birds. As predators, they
hatch their own chicks earlier than those of the species whose
eggs they plunder to feed them.

Why do the birds always nest in the white areas? See cause
and effect, inversion.

This close-up shows the columnar structure of the basalt rock
extruded from the volcanic vent which formed this singular
geological feature.
