Viewers have been watching a pair of puffins incubate a single egg for several weeks via explore.org's webcam, and the chick finally hatched on June 29 at Maine Coastal Islands National Wildlife Refuge Complex.
The tiny gray ball of fuzz will remain in the burrow for about 45 days, and its puffin parents will take turns bringing the baby food, such as sand eels, herring, hake and capelin.
The chick will leave the den when it's able to fly, and it will spend three to five weeks on the rocks and surrounding sea as it reaches maturity.
At this point, the newly adult bird will choose a mate for life.
For the next several weeks, you can watch the puffin chick 24 hours a day as it feeds and grows via the puffin burrow cam.
A second webcam is positioned on the rocks of Maine's Seal Island, which is known as the "loafing ledge," where many puffins can be seen throughout the day.
Both cameras can be viewed below.
