The long-billed curlew (Numenius americanus) is a large North American shorebird. Its diet consists of insects, marine crustaceans, and bottom-dwelling marine invertebrates. The long-billed curlew uses its long, curved bill to reach deep into mud and sand for aquatic invertebrates on its coastal wintering grounds and to pick up insects, including grasshoppers, beetles, and caterpillars, on the breeding grounds.

What You'll Learn
Long-billed curlews eat insects, crustaceans and other invertebrates
The long-billed curlew (Numenius americanus) is a large North American shorebird with a distinctive long, curved bill. This physical feature is not just for show, as it allows the bird to reach deep into mud and sand to extract aquatic invertebrates. The long-billed curlew's diet consists of insects, crustaceans, and other invertebrates.
On grasslands, the long-billed curlew feeds mostly on insects, including beetles, grasshoppers, caterpillars, and spiders. The bird's long bill enables it to probe the ground for these insects, and it has been observed walking or running quickly with its bill extended forward in search of prey. The curlew's bill is also useful for flushing up grasshoppers and other insects during the breeding season.
In coastal areas, the long-billed curlew's diet expands to include crustaceans and other marine invertebrates. The bird uses its long, curved bill to probe small burrows in tidal mudflats and marshes, searching for mud crabs, ghost shrimps, and other creatures. This adaptation allows the curlew to reach prey that other birds cannot access.
The long-billed curlew's diet is not limited to invertebrates. They have been known to eat small vertebrates, such as toads, and even the eggs and young of other bird species. While this behaviour is less common, it demonstrates the adaptability of the long-billed curlew's diet.
The long-billed curlew is a highly migratory bird, travelling long distances between its breeding grounds in grasslands and its wintering grounds in coastal areas. This migratory behaviour influences the bird's foraging habits, as they often forage in relation to the tides rather than the time of day. The long-billed curlew typically forages in small flocks, sometimes joining other shorebird species such as Willets and Marbled Godwits.

They forage in small groups
The long-billed curlew is a large North American shorebird with a distinctive long, curved bill. It is the largest shorebird in the United States, and is part of the Scolopacidae family. This bird species has a diverse diet, and forage in small groups, particularly during migration and on wintering grounds.
Long-billed curlews are often seen some distance away from the shore, and forage in shallow wetlands, marshes, mudflats, and coastal prairies. They are highly migratory, and frequently stray from their normal range. They forage in relation to the tides, rather than the time of day. They are often seen walking quickly, with their long bills extended forward, probing for food in the mud or sand. They also peck at the ground to eat insects and other invertebrates.
The long bill of the curlew allows it to reach deep into mud and sand burrows to feed on aquatic invertebrates, crabs, shrimp, and other small creatures. They also feed on grasshoppers, beetles, caterpillars, spiders, toads, and sometimes the eggs and young of other birds. During the breeding season, they search for prey in groups, walking side by side to flush up grasshoppers and other insects.
The long-billed curlew is a social bird, and they often gather in small flocks, or "curfews", to forage together. They also forage with other shorebirds, such as Willets and Marbled Godwits, which are similar in size and colour pattern, but have upturned bills.

They use their long bills to reach into mud and sand
The long-billed curlew is a large North American shorebird. It has an incredibly long, curved bill, which is longer in adult females than in males and juveniles. The female's bill is also flatter on top, with a more definite curve at the tip, while the male's bill is gently curved throughout.
The long bill of the curlew allows it to reach for food in mud and sand. It uses its bill to probe the mud or other substrates for crabs, shrimp, and other small invertebrates. The bill's end is controlled by separate muscles, allowing it to act like a finger. Curlews often search for prey in groups, walking side by side to flush up grasshoppers and other insects during the breeding season. They also feed on beetles, caterpillars, spiders, toads, and sometimes the eggs and young of other birds.
Curlews are mostly coastal birds, and their foraging techniques are often related to the tides rather than the time of day. They use a variety of foraging techniques, but the most common is probing into wet sand or mud. They are also known to peck at the ground, eating grasshoppers, or simply picking food from the ground or water.
Curlews are graceful creatures and are fascinating to watch as they walk quickly along, feeding and dexterously manipulating their long bills. They are also capable swimmers, with webbed front toes.

Their diet includes beetles, caterpillars, spiders and grasshoppers
The long-billed curlew, a large North American shorebird, has a varied diet. Its long, down-curved bill is well-adapted to foraging for beetles, caterpillars, spiders, grasshoppers, and other insects and invertebrates.
Beetles are a common food source for the long-billed curlew. The bird's long bill allows it to reach into small crevices and burrows to extract these insects. The bill's end is controlled by separate muscles, giving it dexterity and precision when feeding. This adaptation is particularly useful when hunting beetles, as they can be difficult to extract from their hiding places.
Caterpillars are also a part of the long-billed curlew's diet. The bird's pecking technique is well-suited for capturing these insects, as they are often found on the surface of leaves or branches. The curlew's bill can also be used to probe into crevices where caterpillars may be hiding.
Spiders are another food source for the long-billed curlew. The bird has been observed feeding on trap-door spiders, which build burrows in the ground. The pause-probe feeding method is particularly effective for hunting these spiders. This technique involves standing motionless for a few seconds, holding the bill partially submerged and slightly open, then suddenly lurching to capture the prey.
Grasshoppers are an important part of the long-billed curlew's diet, especially during the breeding season. Curlews often search for prey in groups, walking side by side to flush up grasshoppers and other insects. Pesticide spraying has been found to negatively impact curlew populations by reducing their food supply, particularly grasshoppers.

They also eat small marine creatures like shrimp and crabs
The long-billed curlew is the largest North American shorebird. It has a distinctive long, curved bill, which is longer in females than in males. This bird is a member of a large and diverse family of shorebirds, most of which are northern breeders that migrate long distances. The long-billed curlew is a short-distance migrant, travelling from California to Mexico in mid-March, before its nesting grounds dry out.
The long bill of the curlew allows it to reach small marine creatures like shrimp and crabs in their deep burrows in the mudflats. The bird uses its bill to probe the mud or other substrates for food. Its bill is controlled by separate muscles, allowing it to act like a finger. The long-billed curlew's diet also includes other small invertebrates, such as earthworms and insects.
During migration and on the wintering grounds, long-billed curlews forage in small groups, often alongside other shorebirds such as Willets and Marbled Godwits. They can be found foraging in shallow wetlands or resting with their bills tucked under their shoulders. The curlews often gather in small flocks and search for food by walking quickly with their long bills extended forward. They are also able to swim if necessary, as they have webbed front toes.
On grasslands, the long-billed curlew's diet consists mostly of insects, including beetles, grasshoppers, caterpillars, and spiders. They also eat toads and sometimes the eggs and young of other birds. The curlews use their long bills to probe the ground for these food sources.
