NARRATOR: Sometimes
animals aren't just cute.
They're devoted.
Get in the Valentine's
Day spirit with some cute
couples that mate for life.
One of these loyal
animals is the albatross,
the ultimate love bird.
No matter how far the birds
roam away from each other,
they always make it
back to the same place
to breed with the same partner--
and, of course, perform
courtship rituals.
Next up is the macaw, a bird
that also mates for life.
They're known to go above
and beyond basic breeding
by sharing food and even
grooming each other.
Then there's the gentoo penguin.
This cutie takes
courtship to another level
by gifting pebbles to
use as nesting material.
Both faithful parents work
together to incubate their egg
and care for the hatchlings.
This same dual care of the young
can also be found in swans.
Many pairs form
strong bonds for life.
However, if issues occur,
such as a nesting failure,
the swan will seek
out another mate.
Even more birds
that mate for life
include the sandhill crane,
bald eagle, and black vulture.
But monogamy isn't
just for the birds.
Take the beaver.
Paired mates live together
in their own lodge
within the social
colony until the young
are ready to find a monogamous
partner of their own.
Another creature that only has
eyes for one is the dikdik.
Dependent on each
other for company,
they are rarely seen
without their life partner.
Whether it's on land,
underwater, or even in the air,
loving critters can
be found everywhere.
