Redshank Life Cycle: Nest Building To Fledging (and everything in between)
The Redshank (Tringa totanus) is a captivating wading bird that adds a splash of colour to coastlines and wetlands across the UK. Known for their distinctive bright red legs, these medium-sized shorebirds are a common sight in mudflats, marshes, and estuaries.
Redshanks are not just visually striking; they’re also known for their loud, alerting calls that often announce their presence before they’re seen. These vocal birds play a crucial role in their ecosystems, serving as both predator and prey in the complex web of coastal life.
In this article, we’ll explore the life cycle of the Redshank, from nest building to fledging!

How Long Does A Redshank Live?
Redshanks typically live for about 4 to 10 years in the wild. However, some individuals have been known to live longer, with the oldest reaching 26 years of age.
The lifespan of a Redshank is influenced by various factors, including predation, habitat quality, and environmental conditions. Despite facing numerous challenges, including habitat loss and climate change, Redshanks have shown remarkable resilience.
Their relatively long lifespan, combined with their ability to breed from their first year, allows Redshanks to contribute significantly to their population over time.
How Fast Can A Redshank Fly?
Redshanks can fly at speeds of up to 30 to 40 kilometres per hour (19 to 25 miles per hour) when necessary, such as during migration or when evading predators.
While not known for exceptionally high speeds, Redshanks are agile flyers, capable of quick turns and sudden changes in direction. This agility serves them well in their coastal and wetland habitats, allowing them to navigate through flocks of other waders and quickly drop into cover when threatened.
During migration, Redshanks can cover significant distances. Some populations, particularly those breeding in Iceland, undertake impressive journeys to reach their wintering grounds in the UK and other parts of Europe.
Are Redshanks Aggressive?
Redshanks are generally not considered aggressive birds, but they can display territorial behaviour during the breeding season.
During nesting, Redshanks become more protective of their territory. They may engage in aggressive displays towards intruders, including other Redshanks, which can involve loud calls, wing displays, and even physical confrontations if necessary.
Outside of the breeding season, Redshanks are often seen in flocks, demonstrating their sociable nature. These flocks can include other wader species, highlighting the Redshank’s generally peaceful coexistence with other birds.
What Is A Redshank’s Habitat?
Redshanks are highly adaptable birds and can be found in a variety of wetland habitats. In the UK, they favour estuaries, mudflats, saltmarshes, and inland wetlands.
During the breeding season, they nest in saltmarshes and wet grasslands, while in winter, large numbers migrate to coastal wetlands from Iceland, making the UK a vital wintering ground for the species.
This variety of habitats provides Redshanks with abundant food sources such as earthworms, crustaceans, and insects, which they find by probing the mud and soil with their bills.
The UK’s coastal habitats are particularly important for Redshank populations, especially during the winter months when food is scarce in other parts of their range.
How Long Does It Take For A Redshank To Build A Nest?
Redshanks typically take about 2 to 7 days to build their nests. Both male and female participate in the nest-building process, working together to create a suitable home for their eggs and future chicks. Males typically choose the site and build the base, while females line the nest with soft material such as leaves.
The nest is usually a shallow scrape on the ground, often hidden in tussocks of grass or other vegetation. The birds line this scrape with grass, leaves, and other plant material, creating a simple but effective nest.
Redshanks show a preference for nesting in areas with some vegetation cover, which helps to conceal the nest from predators. They often return to the same nesting areas year after year if conditions remain favourable.
Eggs
The egg-laying stage is a crucial part of the Redshank’s breeding cycle. Let’s explore the details of their eggs and laying habits.
When Do Redshanks Lay Eggs?
Redshanks typically begin laying eggs in April, though the exact timing can vary depending on location and weather conditions. In the UK, the egg-laying period generally extends from mid-April to early July.
The timing of egg-laying is crucial, as it ensures that chicks hatch when food is abundant. This strategy increases the chances of survival for the young Redshanks.
How Many Eggs Does A Redshank Lay?
A typical clutch consists of 3 to 5 eggs, although larger clutches are not uncommon in areas with abundant food. Redshanks may lay fewer eggs if food is scarce or if the breeding season is delayed due to cold weather.
If the first clutch is lost early in the season, Redshanks may lay a replacement clutch. However, they usually only raise one brood per year.
What Do Redshank Eggs Look Like?
Redshank eggs are pear-shaped and relatively large for the size of the bird. They measure approximately 44 mm in length and 31 mm in width.
The eggs have a white, pale buff, or olive-green base colour, covered with dark brown or black spots and blotches. This colouration provides excellent camouflage, helping to conceal the eggs from predators when the parent is not incubating.
How Long Do Redshank Eggs Take To Hatch?
Redshank eggs typically take 22 to 24 days to hatch. Both parents share incubation duties, allowing for constant care of the eggs.
During incubation, the parents are highly attentive, rarely leaving the nest unattended. This dedication helps maintain the optimal temperature for embryo development and protects the eggs from predators.
As the hatching date approaches, the parents become increasingly vigilant. The chicks inside the eggs begin to vocalise shortly before hatching, which may help synchronise the hatching process among the clutch.
Chicks
The period from hatching to fledging is a critical time in a young Redshank’s life. Let’s explore this important stage of their development.
How Many Chicks Does A Redshank Have?
A Redshank pair typically raises 3 to 5 chicks per breeding season, corresponding to the number of eggs laid. However, not all eggs may hatch, and not all chicks survive to fledging.
Survival rates for Redshank chicks can vary greatly depending on factors such as food availability, weather conditions, and predation pressure. In favourable conditions, a high percentage of chicks may survive to fledging, while harsh conditions can result in significant losses.
When Do Redshank Chicks Open Their Eyes?
Redshank chicks are precocial, meaning they hatch with their eyes open and are capable of leaving the nest within hours of hatching.
This early development is an adaptation to their ground-nesting lifestyle, allowing the chicks to quickly move away from the nest site if necessary to avoid predators.
When Do Redshank Chicks Fledge?
Redshank chicks typically fledge (gain the ability to fly) at about 25 to 35 days after hatching. However, they become independent from their parents slightly earlier, usually around 20 to 25 days after hatching.
During the period between hatching and fledging, the chicks are cared for by both parents. The adults guide the chicks to suitable feeding areas and protect them from potential threats.
Even after fledging, young Redshanks may stay in family groups for several weeks before fully separating from their parents. This extended period of care helps to improve their chances of survival as they learn to fend for themselves.

Frequently Asked Questions
Redshanks are not currently considered endangered globally. However, they are classified as Amber under the UK Birds of Conservation Concern due to moderate declines in breeding populations.
Some Redshank populations are migratory, while others are resident. In the UK, many Redshanks that breed in Iceland migrate to spend the winter in British coastal areas.
Redshanks primarily feed on invertebrates such as worms, molluscs, and crustaceans. They use their long bills to probe into mud and sand in search of food.
Redshanks are easily identified by their bright red legs. They have a greyish-brown back, white underparts, and a long, straight red bill with a black tip. In flight, they show a white wedge up their back and pale wingbars.
