Description:  Snowy owls are the largest bird species in the Arctic. Snowy owls are predominantly white with dusky brown spots
and bars.   Snowy owls have yellow eyes and their legs and feet are covered in white feathers that protect them from the cold
weather.  Snowy owls are generally solitary and territorial. Territory size varies with prey abundance; during years of abundant prey,
as many as five pairs may hold territories within a square mile whereas pairs are much more widely spaced during years of
scarcity.  Snowy owls are migratory. However, migration in this species is unpredictable and likely related more to prey abundance
than seasons or weather. In general, snowy owls move nomadically and breed when and where prey is abundant.  Unlike most
owls, snowy owls are largely diurnal, or awake, during the day.

Snowy owls are carnivorous. They hunt by utilizing an elevated perch that provides them good visibility while waiting for potential
prey to appear in the hunting area. Visual scanning of the hunting area is facilitated by their ability to swivel their head 270 degrees
around. Their main prey is typically lemmings and mice, however, they also take rabbits, seabirds and fish opportunistically.  Like
other birds of prey, snowy owls regurgitate a small pellet containing undigested bones and hair after they eat.  Alaska’s heaviest
owl, the Snowy Owl, is 23” long and the only species in which the sexes can be easily distinguished. Females and young owls are
heavily barred, while the adult male is almost completely white. This owl has a round head (without eartufts) and yellow eyes. It has
long wings.  This owl is silent except on its breeding grounds where the male gives a low, hollow booming.

Northern Lights

Also know as the Aurora Borealis, these lights are best viewed in the cold dark winter months in Alaska.   The beautiful blaze of the
Northern Lights, or Aurora Borealis, begins when energetic electrically charged particles accelerate along the magnetic field lines
into the upper atmosphere, where they collide with gas atoms, causing the atoms to give off light. The air lights up rather like what
happens in a fluorescent light tube.  The colors reflect gases, the most usual yellow-green color coming from oxygen. Red coloring
is also due to oxygen with a contribution from nitrogen and violet is due to nitrogen. The charged particles originate from the sun,
and it is the “weather” conditions on the sun that decide whether or not we will see the aurora.
