We have a fellow up here in Northern Wisconsin that has a raft and he fills the raft with twigs, branches, weeds, and anchors it away from the shoreline and hopes a pair of loons will find it and make thier nest on it. He has also attached a camera on a stationary object near the home made "island" so that he can watch to see if any loons are attracted to his "island".
Loons are unable to maneuver on land because the drum stick part of their legs is covered by skin and attached to thier body so they only have the front part of the leg, which makes for a good swimmer and diver.
Around the 1st week in May he starts watching to see if the loons are going to participate and make their nest on his ’island’ and luckly around the 5th. of May there are a pair of loons showing interest and they make their nest and lay their eggs (two eggs) unaware that they are being watched. Then they take turms turning the eggs and sitting on them. . Day in and day out they sit - rain or shine, wind or hail - they sit on the eggs for 28 days. They are definately the most patient of all birds and then on the twenty -eighth day the male bird refuses to reliquish the nest and the female bird waits, the chick is hatching and after several hours the chick will appear from under the loon, just a tiny black furry little ball, and soon the other egg will hatch.
They leave the nest within 24 hours and are very dependent on their parents, for there is danger in the waters and with the large turtles, northerns, bass, eagles and other prey, survial is uncertain. So that is what goes on up here in the north country. At least in my small part of the world.
