Curlew Diet and Size: Feeding Habits, Predators, and Measurements
Curlews have remarkable adaptability to various feeding environments, foraging in soft mud and grassy areas where they use their long beaks to help them find food. This skill allows them to do well in a range of habitats, from coastal regions to upland fields.
In this article, we will learn about the Curlew’s diet, how their beak size influences what they eat, and the predators they face. Keep reading to learn more about these remarkable birds.

The Dietary Habits Of The Curlew
In this section, we’ll look at what curlews eat, along with how the length of their beaks and their location affect their food choices.
What Does A Curlew Eat?
The Curlew’s diet mainly consists of invertebrates, which are found in soft mud and wet soil. Using their long, sensitive beaks, they find shellfish, worms, and shrimps, relying on their touch sensitivity to locate these prey.
Depending on the region and the sex of the curlew, crabs and molluscs might also be part of their diet, with males favouring crabs as their shorter beaks are not as well-suited for digging deeply into the ground as those of females.
What To Feed A Baby Curlew?
Chicks of Curlews rely on a diet of insects, worms, and various small creatures that can be found on or near the surface of the ground. Adult birds use their long, sensitive bills to find and pull these invertebrates from the mud or soft soil, making it easier for the chicks to eat. This rich protein source supports their rapid growth and development in the early stages of life.
Breeding Habits Of Curlews
Ground nesting is a common trait of the Curlew, making a simple scrape mostly in upland regions like moors and rough pastures during spring and summer. They prefer open habitats that provide a good view to watch for predators, often found near water bodies like wet grasslands and marshy areas.
The nesting period starts around April or May, during which curlews generally lay a clutch of four eggs. Both parents take part in incubating the eggs and later in feeding their precocial chicks, which are quite mature and mobile soon after hatching.
Curlews show a strong site fidelity, often returning to the same breeding sites annually. They are also territorial during the breeding season, defending their nesting area from others of their species. This behaviour helps minimise competition for resources among breeding pairs.
Do Curlews Mate For Life?
Curlews are known to form long-term pair bonds, often remaining with the same mate throughout different breeding seasons. This monogamous behaviour helps them work together effectively in raising their young each year.
Their habit of returning to the same breeding areas each year supports this bond, allowing them to reconnect with the same mate over different seasons. However, these bonds aren’t always permanent. Changes can occur in partnerships, especially if they fail to breed successfully or if one of the partners dies.
The Size & Weight Of Curlews
Let’s look at the weight range of Curlews and their impressive size, including their length and wingspan.
How Much Does A Curlew Weigh?
Generally, Curlews weigh between 575 grams and 1,000 grams. Females tend to be larger than males, though the size differences are often subtle. When observed side by side, females not only have a higher weight but also have a longer bill, making it easier to tell them apart.
How Big Is A Curlew?
Measuring between 50 to 60 centimetres long, the Curlew is a large shorebird, with a wingspan that ranges from 80 to 100 centimetres. This size makes it the largest wader within its geographical area, which includes a variety of habitats across Europe and Asia.
Are Curlews Under Threat?
Facing serious threats, the Curlew is classified as Near Threatened on the global IUCN Red List and is placed in the Red category within the UK’s Birds of Conservation Concern.
Habitat loss due to urbanisation and intensive agricultural practices poses challenges, disturbing their breeding and feeding areas. Climate change worsens these problems by changing weather patterns that impact their habitats.
Additionally, human activities, such as construction and recreational use of land, contribute to their declining population. Even though hunting is banned in many areas, predation and previous hunting practices have also contributed to their numbers falling.
What Eats A Curlew?
Among the primary threats to Curlews are red foxes, known for hunting their eggs and chicks. These foxes are skilled at finding nests, making it easy for them to dig up eggs or capture chicks. Curlew nests also face dangers from other predators, like crows and magpies.
Where Can I See Curlews In The UK?
When it comes to observing the Curlew, several locations in the UK stand out, including Nigg Bay in Scotland. This site is known as an ideal bird watching spot, especially from the hides available at the reserve.
Other well-known sites include Morecambe Bay, Solway Firth, the Wash, and the Dee, Severn, Humber, and Thames estuaries, all recognised for their curlew populations during winter migration.
In Shropshire, the Weald Moors is famous for its wetland habitats, which support various wading birds, including the curlew. Spring and early summer are excellent times to observe the curlew’s breeding activities and hear their unique calls.
Caerlaverock in Scotland and Castle Espie in Northern Ireland are centres for observing curlews, especially during winter months when large flocks gather. These centres offer guided walks and hides for watching curlews and other waterbirds.
