Little blue penguins are the smallest species of penguin in the world. When visitors step up to their exhibit across from the Gift Shop, many exclaim, "Aww, look at the babies!" Except they're not babies. While they are petite and noticeably smaller than their African and rockhopper neighbors, the birds on exhibit are not babies.

BUT! This spring, the babies weren't far. We're thrilled to share that five little blue chicks hatched earlier this year and have been growing up behind the scenes in the comfort and safety of their parents' watchful eyes (with a little help from our penguin team).

Four of the five little blue penguins born at the Aquarium this year.

The chicks hatched from their eggs around April. Two of the little ones made their media debuts just before Mother’s Day in a video celebrating mothers around the world, including their own. In fact, their mom, 9-year-old Carnac was also hatched here in Boston. She is an experienced mom having raised three other chicks before.

Now it's time for others to shine! This year's chicks are in various stages of development, one is still poofed out in its downy gray feathers, the rest have grown their handsome blue and white waterproof feathers and have already joined the adults on exhibit! The little one will remain behind the scenes with its parents while it matures. So while you can visit these newbies on exhibit, we're pretty sure you'll still want to see their baby pictures.

Brace yourself, this is some serious cute.

Few things are cuter than a fluffy jumble of penguin chicks.

The chicks wear temporary ID bracelets on their wings so the penguin biologists can tell them apart.

They may be small, but little blue penguins can make a racket!  These little blues are sporting the downy feathers of a younger chick.

This chick has lost most of its downy feathers and you can see its white belly and lovely blueish feathers growing in.
