As indicated previously, adult puffins mostly eat small fish, such as sand eels, herring, sprats, hake, and capelin.
In Witless Bay capelin abound, a favorite of humpback whales in the area, but as a non-fish expert I cannot
vouch for the identity of the fish in these two images of the same puffin.

These and the remaining images were taken in a third area that our wonderful guide Tony Power took us to.
