Why Do Arctic Bird Cliffs Have Bright Green Grass and Orange Rocks?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do Arctic bird cliffs have bright green grass and orange rocks?

The Big Idea

Arctic bird cliffs are green and orange because seabirds feed the plants without trying! Their droppings work like fertilizer. That makes grass and orange lichens grow lush and bright. Let's see how!

Fish from the Sea

Step one: fish from the sea. Seabirds catch fish in the ocean and carry the food back to the cliffs. They also leave droppings there, lots of them, since thousands of birds live together.

Natural Fertilizer

Step two: natural fertilizer. The droppings act like fertilizer, so grass grows lush and green below the nests. Plants love the extra nutrients, which are scarce in the Arctic otherwise.

Orange Rocks

Step three: orange lichens. Orange lichens love the extra nutrients and cover the rocks above the nests. The cliffs look like colorful paintings, all thanks to the birds' food.

A Closer Look

Let's take a closer look! Birds bring fish from the sea. They nest on the cliffs. Green grass grows lush below the nests, where the nutrients wash down. And orange lichens cover the rocks.

Quick Facts

Quick facts! Seabird droppings carry sea nutrients onto land. The food turns into plant food, so it helps the whole area. Insects, foxes, and other animals also live around bird cliffs. Watch bird cliffs from far away, and with a grown-up.

Think Like a Scientist

Now, think like a scientist! Draw a cliff with the sea at the bottom. Use arrows to show fish going to birds, and nutrients going to plants. Can you follow the whole trip? Share what you discover with a grown-up.
