Little is known about the habits
and behaviors of the six species of penguins that live in the extreme
environments of Antarctica, especially in the winter when conditions are too harsh for scientists to observe them.
What scientists do know is that some of these species are thriving while others are dwindling in numbers.
To better understand some of these species of penguins and what's
causing changes in their populations, Tom Hart, a penguinologist at
Oxford University, set up cameras in 2014 in spots along the Antarctic
coastline where penguins frequent.
Since then, these cameras have recorded video and snapped over
500,000 images of thousands of penguins. Although the team is still
reviewing oodles of data they have collected, here's a small sample of
some of the incredible pictures the team collected.
Many species of penguins spend most of their time at sea, making it difficult for scientists to study their behavior.
Most
Antarctic species will migrate to the shorelines to breed during the
fall. It's on these shorelines that Hart and his team spied on thousands
of penguins for a full year.
One
of the only ways to study penguins is to attach GPS trackers on
individual birds. The team's cameras are less invasive and provide a
better idea of population size.
The
first thing penguins do when they reach the shore is locate their mate.
If they have mated before they relocate that same penguin using a
unique call, or song.

With every penguin trying to relocate their mates, the first few days of mating season can get pretty noisy.
If the penguins have not mated before, they engage in courtship activities like bowing their heads.

Another display of courtship is swinging their heads from side to side, like so:
Hart
has discovered that the Adélie penguin species, shown here, are not
responding well to warmer climates in the Antarctic Peninsula where
their numbers are declining.
Gentoo penguins, on other hand, are perhaps the only Antarctic penguin species who are adjusting well to the warmer climates.
Emperor
penguins are the largest of all the 17 penguin species in the world.
These birds are famous for having the most stressful breeding habits of
any penguin species because they travel miles inland to breed during the
harshest time of year: winter.
Here's
a colony of king penguins, which look similar to Emperor penguins and
are the second largest species of penguin. They breed during the summer
months of November through January.
Although
they can't fly, penguins soar through water. They use their flippers
for propulsion and their feet as a rudder. Capable of exceeding 12 mph,
they can hold their breath for 15 to 20 minutes and dive over 250 feet
below the surface.
The
Antarctic coastlines aren't just a popular place for penguins. These
seals don't seem to mind the company, but this Adélie penguin looks a
bit disgruntled.
Although
Hart and the team are still analyzing the data, they did report one
interesting find from their latest Antarctic expeditions: If the ground
is too cold for breeding, some penguin species will use their poo to
warm it up.
Hart
and his team recently launched a citizen science project called Penguin
Watch that released 500,000 new images of penguins asking the public to
help his team individually count the number of penguins in each photo.
How many can you count in this photo?
Everyone
who registers to help out with Penguin Watch can also enter to win a
trip to Antarctica to see the penguins for yourself. As of April, more
than 1.5 million people have volunteered.
