Amaze-wing Facts About The White Rumped Sandpiper

Check out these awesome white rumped sandpiper facts.

The white rumped sandpiper (Calidris fuscicollis) is a migration bird and a species of shorebird. They are of the order Charadriiformes,  family Scolopacidae, and are part of a group of sandpipers or waders. Shorebirds are a group of species of birds found in the mud, ground, or sand near bodies of water. They are typically found in North America and sometimes in South America. This means that they often fly to different locations depending on the season and for breeding.

The rump of a bird is the area of its body just above the tail feathers. Don't be fooled, even though they are named a 'white rumped' sandpiper, sometimes the rump is actually dark brown!

These birds are a species known for their graceful long wings and the males who are very vocal. Thankfully, these birds are not endangered and there are plenty to be seen in the wild. They have a conservation status of Least Concern. However, their populations are said to be decreasing. This is mostly due to habitat loss because of climate change. The high Arctic is in danger and is no longer safe for all birds. It is important to learn about climate change and nature's amazing creatures so that we can preserve our planet and its animals forever.

Did you know...

The white rumped sandpiper actually has dark rump feathers!

The oldest white rumped sandpiper recorded was at least seven years old. It was banded for recording in Quebec in 1972 and discovered in Nunavut in 1978.

Their feeding depends on the tides. When it is low tide, they feed more because there is more prey to be found on uncovered mud and sand.

This bird is also prey for other animals. Arctic foxes love to prey on eggs and young white rumped sandpipers and can be found hunting on their breeding grounds. Sometimes they can even be prey to other birds including the peregrine falcon.

This bird has the longest migration route of any bird in North America. Actually, birds flying south have been said to fly from high arctic Canada to southern South America and the surrounding islands. To make migration journeys down south, this bird flies over the Atlantic ocean and crosses the Amazon basis. This migration trip normally takes a month.
