What sound do puffins make?
Puffins make loud growling calls usually from underground which sounds like a muffled chainsaw. The chicks "peep" for food from parents.
The most obvious difference is flight. Penguins can't fly and puffins can. Puffins have longer feathers and don't live in the cold places that most penguins do. Most penguins are larger than puffins. Puffins have short, stubby, colorful, conical bills while penguins have longer, pointier bills. Puffins have pointy feathers behind their eyes and penguins don't. Try to look up images of penguins and puffins and compare the difference.
In the past, puffin numbers have suffered as the birds' pelts have been used for clothing and their eggs prized by collectors. However, North Atlantic puffins, with an estimated population of six million, are neither extinct nor endangered. Puffins are adaptable to a wide range of conditions. Elsewhere, horned puffins and common puffins have not suffered a dramatic drop in population, but tufted puffins have fallen in numbers.
