What Do Puffins Eat?

Puffins are some of the most beloved birds worldwide. Their colourful beaks, fat white bellies, and penguin-like strutting while on land makes them a firm favourite for any bird watcher. But what does the puffin eat? We’re looking at what is on the menu for these beautiful birds below, and some of their dietary habits may be shocking to you.

Puffins hunt herring, capelin, hake and sand eels primarily. They will eat molluscs and shrimp too. A puffin’s diet greatly depends on the food sources in the area.

While many puffins eat almost exclusively fish, as we’ll see below, their diets can even change from colony to colony.

As puffins live across many different coastal areas around the world, their diets are nice and varied, as it greatly depends on what food is in the area. The time of year can even dictate what a puffin will put on its plate. Puffins have been known to hunt crabs, jellyfish, shrimp, molluscs and many different fish species.

What do puffins eat in the wild?

Puffins eat a wide variety of things in the wild. Their diet can include crabs, herring, hake, sand eels, shrimps, octopus, squid and molluscs. As long as it is seafood, a puffin will happily hunt and eat it.

Puffins have adapted to their local environments, so food sources for different colonies can be vastly different. Still, though, puffins tend to choose small fish and molluscs for most of their meals.

What are puffins favourite food?

It is difficult to say what a puffin’s favourite food is, as even from colony to colony, their diet habits can change.

However, puffins do love to eat small fish. They can hold a fish of up to 18cm (7 inches) in their beak, but most opt for smaller fish of around 7cm (3 inches).

We aren’t sure if the puffins favour smaller fish for their taste or because they can catch more of them quickly and easily.

How do puffins eat their food?

You may have seen puffins with fish sticking out their iconic beak as they make their way back to their nest to eat them. The puffin doesn’t simply gobble all the fish at once.

Instead, it takes them back to the nest, gives some to the baby if they have a baby at the time, and then eats them one by one until their plate is empty.

They eat about 40 fish a day, so they need a few trips out to sea per day to fill their belly. They will often eat smaller fish underwater as they hunt too.

How do puffins find food?

Puffins fly through the water, using their wings to propel themselves and their feet to steer. They hunt by sight while underwater and will make several short dives to catch up to 10 fish at once.

They dive to about 60 meters but can’t hold their breath for more than about 30 seconds. So several quick, deep dives are needed to fill their beaks.
