Both feet...no seriously though, I've seen loons 15-feet underwater. They might go deeper.
For standing on.
actually loons can fly they migrate during winter so yeah they do.
Herons have long legs and small feet and long toes.
Loons, like most creatures have 2 eyes, so the formula will be radius of their eye, times how far they are away, that will be focus. About 25 feet, they will be able to see about 35 feet with a dim outline on land
two toes in front, two behind
two toes in front, two behind
they use them to dig their burrow nests.
no thay dont thay have wings
Loons build their nests on the shore of freshwater lakes or ponds. The male loon will return to the same nesting area year after year. Loons dive to catch fish, crayfish, and small amphibians such as tadpoles and frogs. The loon catches its prey with its long-pointed bill and swallows it whole while still underwater. Loons grow to 2-3 feet in length
Loons are a type of waterfowl, and have webbed feet much like a duck or goose.
A loon is similar to a duck and uses its feet to swim and then "ducks" ;D down and grabs the fish (like a duck does). A heron walks across shallow water and dips their head down, catching the fish, and the kingfisher just uses its wings to levitate and then swoops down and grabs its prey.
