Redshank Diet and Size: Feeding Habits, Predators, and Measurements
The Redshank (Tringa totanus) is a distinctive wading bird that graces the coastlines and wetlands of the United Kingdom. Known for its vibrant red legs, which give it its name, the Redshank is a medium-sized member of the sandpiper family. These birds play a crucial role in coastal ecosystems and are a delight for birdwatchers across the country.
In this article, we’ll explore the dietary habits, breeding patterns, size, and conservation status of the Redshank, providing valuable insights into this charismatic coastal resident!

The Dietary Habits Of The Redshank
Redshanks have a varied diet that adapts to their coastal and wetland habitats, changing with the seasons and food availability.
What Does A Redshank Eat?
Redshanks primarily feed on small invertebrates found in mudflats, saltmarshes, and coastal areas. Their diet consists mainly of insects, molluscs, crustaceans, and worms. They use their long, sensitive bills to probe into mud and shallow water, searching for their prey.
During the breeding season, Redshanks consume more insects and their larvae, which provide the necessary protein for egg production and chick growth. In coastal areas, they feed on small crustaceans like shrimp and tiny crabs, as well as marine worms and small molluscs.
In winter, when insect populations decline, Redshanks adapt by incorporating more marine invertebrates into their diet. They can often be seen foraging in groups, moving methodically across mudflats and shallow waters in search of food.
What To Feed A Baby Redshank?
Baby Redshanks, known as chicks, are precocial, meaning they can feed themselves shortly after hatching. However, they initially rely on their parents for guidance to suitable feeding areas.
In the wild, Redshank chicks primarily eat small insects and other invertebrates. Their parents may lead them to areas rich in tiny crustaceans, flies, and other soft-bodied insects that are easy for the chicks to consume and digest.
Breeding Habits Of Redshanks
Redshanks have interesting breeding behaviours that are well-adapted to their coastal and wetland habitats.
Do Redshanks Mate For Life?
Redshanks are often monogamous, with many pairs remaining together for multiple breeding seasons. While they don’t necessarily mate for life in the strictest sense, they do show a strong tendency towards long-term pair bonds.
During the breeding season, Redshanks perform elaborate courtship displays, including aerial chases and ground-based rituals. Males often perch on fence posts or other elevated spots, calling loudly to attract females and defend their territories.
Pairs frequently return to the same breeding areas year after year, which can contribute to their long-term monogamy. This site fidelity allows them to take advantage of familiar, successful breeding grounds.
The Size & Weight Of Redshanks
Redshanks are medium-sized waders, well-proportioned for their coastal lifestyle.
How Much Does A Redshank Weigh?
Adult Redshanks typically weigh between 110 to 140 grams. Males are slightly lighter, averaging around 110 grams, while females are a bit heavier, averaging about 130 grams.
This relatively light weight allows Redshanks to be agile both on the ground and in flight. Their weight can fluctuate seasonally, with birds often being heavier before migration when they build up fat reserves for their long journeys.
How Big Is A Redshank?
Redshanks measure approximately 28 cm in length from bill to tail. They have a wingspan of about 62 cm, which enables them to perform their agile flight displays and navigate coastal winds effectively.
Their long legs, which can be up to 50% of their body length, are well-adapted for wading in shallow waters and mudflats.
Are Redshanks Under Threat?
Redshanks face several challenges in the UK and are currently classified as Amber under the UK Birds of Conservation Concern. Globally, they are listed as Least Concern on the IUCN Red List of Threatened Species.
The main threats to Redshanks include habitat loss due to coastal development and sea-level rise, which affects their breeding and feeding grounds.
What Eats A Redshank?
Redshanks face predation from various sources. Adult birds are preyed upon by birds of prey such as Peregrine Falcons and Sparrowhawks. Their eggs and chicks are vulnerable to predation by gulls, crows, and mammals like foxes and stoats.
To protect themselves and their young, Redshanks have developed several defence mechanisms. They are highly vigilant and will give loud alarm calls to warn others of approaching danger.
When nesting, they rely on camouflage and will only flush from the nest at the last moment to avoid revealing its location.
Where Can I See Redshanks In The UK?
Redshanks can be seen year-round in the UK, with numbers increasing in winter due to the arrival of migratory birds from Iceland and other northern regions.
During the breeding season, which is from April to July, Redshanks can be found in coastal saltmarshes, wet grasslands, and inland marshes. Key breeding areas include the east coast of England, particularly in Norfolk, Suffolk, and Lincolnshire.
In winter, Redshanks are more widely distributed around the UK coastline. Excellent places to spot them include estuaries such as the Dee Estuary in Cheshire, the Humber Estuary in Yorkshire, and the Thames Estuary in the southeast.
