Readers ask: How deep can a loon dive?

Almost wholly aquatic, loons can swim long distances underwater and can dive from the surface to a depth of 60 metres (200 feet). Besides having solid bones, loons can further decrease their buoyancy for these dramatic dives by compressing air from their lungs, feathers, and internal air sacs.Almost wholly aquatic, loons can swim long distances underwater and can dive from the surface to a depth of 60 metres (200 feet).
