Curlew Sandpiper Diet and Size: Feeding Habits, Predators, and Measurements
Curlew Sandpipers are charming waders known for their slender builds and uniquely long, curved bills that help them in their search for food. During the breeding season, their deep chestnut plumage adds to their appeal.
In this article, we will look at their feeding habits, body measurements, and the predators they face in their habitat. Keep reading to learn more.

The Dietary Habits Of The Curlew Sandpiper
Let’s take a look at the diet of the Curlew Sandpiper, including what it eats in its habitat and what it feeds its young.
What Does A Curlew Sandpiper Eat?
The Curlew Sandpiper primarily consumes a variety of small invertebrates, which include insects, crustaceans, and worms. Its diet typically includes flies, beetles, and small molluscs and crustaceans such as amphipods, brine shrimps, and copepods. From time to time, seeds may also be part of its diet. This bird usually forages in soft mud found on marshes and coasts, where its keen eyesight helps it locate food.
What To Feed A Baby Curlew Sandpiper?
Adult Curlew Sandpipers feed their chicks with a diet primarily made up of insects and their larvae during the breeding season. This kind of diet is typical for waders since it provides essential nutrients for the growth and development of the chicks. After the breeding season, both adult and juvenile Curlew Sandpipers primarily feed on small marine animals.
Breeding Habits Of Curlew Sandpipers
High arctic regions of Siberia serve as the primary breeding grounds for Curlew Sandpipers, who choose tundra habitats near freshwater for nesting. They have a unique breeding behaviour where males perform courtship displays but only stay in the breeding area for around 10 days.
After mating, the males depart, leaving the females to stay longer to incubate the eggs and look after the chicks. Once the chicks are independent, which usually takes 14 to 16 days after hatching, the females also leave for southern wintering grounds.
Do Curlew Sandpipers Mate For Life?
Known for being socially monogamous, Curlew Sandpipers pair up during the breeding season to mate and raise their chicks. This bond, however, usually only lasts for a single breeding season instead of being permanent.
Pairings often change from one season to the next, rather than forming a lifelong connection.
The Size & Weight Of Curlew Sandpipers
Let’s take a look at the weight and size of Curlew Sandpipers and why there are some small differences between males and females.
How Much Does A Curlew Sandpiper Weigh?
The average weight of the Curlew Sandpiper ranges from 45 to 90 grams. In particular, females are often heavier, which plays an important role in aiding egg production and incubation.
How Big Is A Curlew Sandpiper?
A small to medium-sized wader, the Curlew Sandpiper typically measures around 18-23 cm in length and has a wingspan of 38 to 41 cm. This makes it a bit larger than a Dunlin, another type of sandpiper.
Are Curlew Sandpipers Under Threat?
Considered a vulnerable species, Curlew Sandpipers are currently under threat globally, as reported by the IUCN Red List. Their status has been escalated from ‘Near Threatened’ to ‘Vulnerable’ following a global population decrease of over 30%.
This decline is largely due to habitat loss, degradation, disturbances, hunting, and the consequences of climate change.
In the UK, the Curlew Sandpiper is listed as an ‘Amber’ species, which indicates that they are of medium conservation concern due to the pressures on their population and habitats.
What Eats A Curlew Sandpiper?
Predators of the Curlew Sandpiper in the Arctic, particularly during the breeding season, include the Arctic Fox, various birds of prey like skuas, and gulls.
The Arctic Fox preys on the eggs and chicks of shorebirds, including the Curlew Sandpiper, especially in years when lemmings are in short supply. Such predation can have a major impact on the breeding success of Curlew Sandpipers, which can also change their migration and moult timing.
Where Can I See Curlew Sandpipers In The UK?
Curlew Sandpipers can be seen in the UK during their migration periods, especially in the autumn months. Coastal and estuarine locations are some of the best spots for birdwatching. Titchwell Marsh in Norfolk is known as a top location for spotting these birds.
They can also be found along the east and southern coasts of England in areas like salt marshes, muddy pools, and coastal lagoons from April to May and again from July to October. These regions provide excellent conditions for observing Curlew Sandpipers as they rest and feed during their long migrations.

Frequently Asked Questions
The difference between a Curlew Sandpiper and a Dunlin lies in their size and plumage. Curlew Sandpipers are larger with a typical length of 18-23 cm and a wingspan of 38 to 41 cm, and they display a distinct deep chestnut plumage during the breeding season. In contrast, Dunlins are smaller and lack the uniquely long, curved bills of the Curlew Sandpipers.
Threats to the Curlew Sandpiper include habitat loss, degradation, disturbances, hunting, and the effects of climate change. These factors have led to a global population decrease of over 30%, and the species is currently listed as vulnerable on the IUCN Red List.
