Curlew Sandpiper Cycle: Nest Building To Fledging (and everything in between)
Curlew Sandpipers stand out in flight due to their long, curved bills and a striking white rump. During autumn, they show a softer, paler appearance with a white eyestripe, while in spring and summer, their plumage shifts to a deep chestnut for breeding.
In this article, we will look at the life cycle of the Curlew Sandpiper, including their nest construction, the timing of when they lay their eggs, and the growth of their chicks before they first take to the skies. Keep reading to find out more.

How Long Does A Curlew Sandpiper Live?
The lifespan of a Curlew Sandpiper usually reaches about 10 years in the wild. However, some have been recorded living as long as 19 years.
How Fast Can A Curlew Sandpiper Fly?
During migration, the Curlew Sandpiper can reach an average speed of about 65 km/h. This speed is vital for a species that makes one of the most remarkable migrations among shorebirds, spanning continents and hemispheres.
Are Curlew Sandpipers Aggressive?
Curlew Sandpipers aren’t usually seen as aggressive birds. They are very social and often gather in flocks with other wading birds, like Dunlins. While there may be some territorial or competitive behaviours during the breeding period, these are often limited and not significantly aggressive.
What Is A Curlew Sandpiper’s Habitat?
The Curlew Sandpiper primarily inhabits coastal wetlands and mudflats, which are crucial for feeding and breeding. During the breeding season, these birds are found in the lowland tundra of Siberia, often nesting near marshes or pools. Their nesting sites are usually on dry patches of tundra, providing safety for their eggs and young.
When the breeding season ends, Curlew Sandpipers migrate to various locations such as Australia, Africa, Southern Asia, and South-east Asia, where they are commonly observed on intertidal mudflats of lagoons, estuaries, and mangroves, along with beaches and rocky shores. These habitats are suitable for their diet, which mainly includes small invertebrates.
How Long Does It Take For A Curlew Sandpiper To Build A Nest?
Nests built by Curlew Sandpipers are generally simple, consisting of shallow scrapes in the ground that are lined with bits of vegetation. Given their simplicity, the time taken to build these nests can vary from a few hours to a few days.
Eggs
Let’s look at the timing of egg-laying of Curlew Sandpipers, the typical number of eggs, their appearance, and the time they take to hatch.
When Do Curlew Sandpipers Lay Eggs?
The eggs of Curlew Sandpipers are usually laid from mid-June until late August. This aligns with the brief Arctic summer, allowing enough time for incubation and chick growth before their migration.
How Many Eggs Does A Curlew Sandpiper Lay?
A typical clutch for Curlew Sandpipers consists of four eggs. This is commonly seen in numerous shorebird species, allowing them to handle incubation and the care of their young efficiently within the short breeding season of the Arctic.
What Do Curlew Sandpiper Eggs Look Like?
The eggs of the Curlew Sandpiper are generally yellow, cream, or olive with dark markings. This particular pattern allows the eggs to blend into the surrounding tundra habitat, helping them avoid predators.
How Long Do Curlew Sandpiper Eggs Take To Hatch?
It generally takes about 19 to 20 days for Curlew Sandpiper eggs to hatch. During this time, the female focuses on keeping the eggs warm, while the male helps to watch the nest for any possible predators.
Chicks
Here, we’ll look at Curlew Sandpiper chicks, from how many they have, when they first open their eyes, and when they’re ready to fledge.
How Many Chicks Does A Curlew Sandpiper Have?
Generally, Curlew Sandpipers lay four eggs, which means they can have up to four chicks each time they breed. However, the number of chicks that actually hatch and survive can differ based on factors such as predation, the environment, and the availability of food.
When Do Curlew Sandpiper Chicks Open Their Eyes?
Precocial in nature, Curlew Sandpiper chicks hatch with their eyes open and downy feathers. This helps them be fairly mature and able to move around shortly after hatching. As a result, they can leave the nest and follow their parents to feeding spots within just a few hours.
When Do Curlew Sandpiper Chicks Fledge?
Curlew Sandpiper chicks usually fledge around 14 to 16 days after they hatch. Until they are ready to fledge, these chicks are especially at risk from predators and harsh weather. Fledging at 14 to 16 days reduces this vulnerable period, allowing them to fly away from ground predators. It also gives them the chance to start honing their flying skills, which are essential for their migration to warmer regions.
