The Aquarium participates in a Species Survival Plan for our penguins. Right now is little blue penguin breeding season. Over the coming weeks we'll share behind-the-scenes pictures and details about what it takes to raise penguins chicks on Central Wharf. Catch up on what you missed!

Given their small size we are often asked if the little blue penguins are babies. All of the little blue penguins on exhibit are full grown adults or juveniles. The little blue penguin is the smallest species of penguin and stand at about 10-12 inches tall and weigh 2-3 pounds. In fact, many visitor at the Aquarium ask if the little blues are babies. Nope!

If the adults are that small, can you imagine how small the chicks are? When a little blue chick pips out of its shell it usually weighs between 30–40 grams, which is only about 1–1.5 ounces! That’s about the weight of a Hershey Bar.

This photo was taken shortly after this chick finished hatching and weighed less than 40 grams.

These tiny little chicks grow very fast. In about a month’s time they can weigh as much as their parents. These “big babies” are still covered with down and rely on their parents for food until it fledges. Once fledged, they have their first set of waterproof feathers; at this time they are ready to swim and get food on their own.

Here are some photos of our little blue penguin chicks that were born behind the scenes.

Getting bigger

This chick is about 2 weeks old; it can still fit under its parents for protection but not for long

It takes a lot of food to grow that fast, this chick is opening up its beak showing that it is hungry and ready for a meal

This chick is about one month old, and as you can see it is the same size as its parents but is still covered in down.

At about 6 weeks old this chick has started to fledge. Its first set of waterproof feathers has started to replace its down.
