Two of explore.org's wildlife webcams are back, and if you watched Maine's ospreys and puffins last year, you'll see some familiar faces.
Ospreys Steve and Rachel, the monogamous life partners, have returned to their nest on Hog Island.
After wintering in South America, the birds arrived in late April and now have a couple of chicks. They're still waiting on three others to hatch.
Rachel does most of the incubation, while Steve provides her with meals of fish.
Osprey eggs incubate for 35 to 42 days, and about 50 days after hatching, the young begin exercising their wings and taking their first practice flights.
In September, the chicks will begin their solo journey to South America for the winter.
And if puffins are more your thing ...
In addition to the live osprey webcam, explore.org also has two Atlantic puffin cams on Seal Island in Maine.
One of the cameras shows the inside of a puffin burrow, and the other is known as the loafing ledge (both below), where several of the birds can often be seen resting on the rocks.
Atlantic puffins spend most of their time at sea, only coming to land in the spring to breed.
They lay one egg in a burrow, and the male and female share incubation duties for about 39-45 days. Once the chick hatches, both parents provide it with fish.
