Temminck’s Stint Life Cycle: Nest Building To Fledging (and everything in between)
The Temminck’s Stint, or Calidris temminckii, is a small, elusive wader that breeds in the northern regions of Europe and Asia. Named after the Dutch ornithologist Coenraad Jacob Temminck, this bird is known for its remarkable migratory journeys and distinctive breeding habits.
With a preference for freshwater habitats, the Temminck’s Stint offers a fascinating glimpse into the life of shorebirds.
This article explores the life cycle of Temminck’s Stint, from nest building to fledging, and answers key questions about their lifespan, flying speed, aggressiveness, habitat, nesting period, and chick development.

How Long Does A Temminck’s Stint Live?
Temminck’s Stints typically live for about 5 to 7 years in the wild. However, some individuals have been known to reach up to 10 years of age.
This lifespan is relatively long for a bird of its size, considering the challenges it faces during its annual long-distance migrations. Factors such as predation, habitat loss, and climate change can impact their longevity. The bird’s ability to adapt to various environments during its migratory journey contributes to its survival.
Interestingly, Temminck’s Stints reach sexual maturity in their first year, allowing them to contribute to the population from an early age. This early breeding capability is crucial for maintaining stable populations, especially given the various threats these birds face in their habitats.
How Fast Can A Temminck’s Stint Fly?
While not known for extremely high speeds, Temminck’s Stints make up for it with their stamina. They can cover vast distances, sometimes flying non-stop for several days during migration. On average, the Temmink’s Stint flies at 46.8 kph (or around 13 metres per second).
Their flight is typically swift and direct, with rapid wing beats that allow them to maintain a steady pace over long periods.
Are Temminck’s Stints Aggressive?
Temminck’s Stints are generally not aggressive birds. They are known for their peaceful and shy nature, often avoiding confrontations with other birds.
During the breeding season, males may display territorial behaviour, but this is usually limited to vocal displays and aerial chases rather than physical aggression. They use a distinctive trilling call to establish and defend their breeding territories. This call, described as a rapid, high-pitched “tirr-irr-irr”, is often the first sign of a Temminck’s Stint’s presence in its breeding habitat.
Outside of the breeding season, Temminck’s Stints are often seen in small flocks, foraging peacefully alongside other wader species. Their non-aggressive nature allows them to coexist with various shorebirds in shared feeding areas, which is beneficial during their energy-demanding migratory periods.
What Is A Temminck’s Stint’s Habitat?
Temminck’s Stints prefer freshwater habitats with muddy or pebbly shores. During the breeding season, they inhabit the arctic and subarctic tundra regions of northern Europe and Asia.
In their breeding grounds, these birds favour areas near lakes, rivers, and wetlands with low vegetation. They often nest in damp, grassy areas close to water bodies. The tundra provides them with an abundance of insects and small invertebrates, which form the bulk of their diet during the breeding season.
How Long Does It Take For A Temminck’s Stint To Build A Nest?
Temminck’s Stints take approximately 3 to 5 days to build their nests. The female selects a site, usually on the ground in a well-hidden location amidst vegetation or rocks.
The nest is a simple scrape lined with plant material, feathers, and moss. This minimalistic approach ensures quick construction and effective camouflage from predators.
The choice of nesting site is crucial for the protection of eggs and chicks from predators and environmental factors such as flooding and extreme temperatures.
Eggs
The egg-laying process is a crucial phase in the Temminck’s Stint’s life cycle, marking the beginning of a new generation. Let’s explore the various aspects of their eggs and laying habits.
When Do Temminck’s Stints Lay Eggs?
Temminck’s Stints typically lay eggs from May to June, depending on their location and local climate conditions.
The timing of egg-laying is crucial for these birds, as they need to ensure their chicks hatch when food is most abundant.
Interestingly, Temminck’s Stints have a unique breeding system where females may lay two clutches of eggs. The first clutch is usually incubated by the male, while the female may move to a new territory and lay a second clutch with a different mate.
This strategy, known as double-clutching, allows the species to maximise its reproductive output during the short breeding season.
How Many Eggs Does A Temminck’s Stint Lay?
A Temminck’s Stint typically lays a clutch of 3 to 4 eggs, although clutches of 5 eggs are not uncommon.
This clutch size is well-adapted to their breeding strategy and environment. Laying four eggs allows the parents to invest significant energy in each offspring while still having a good chance of successfully raising multiple chicks to fledging.
What Do Temminck’s Stint Eggs Look Like?
Temminck’s Stint eggs are pear-shaped and measure approximately 28 to 31 mm (2.8 to 3.1 cm) in length and 20 to 22 mm (2 to 2.2 cm) in width. They have a pale buff or olive background colour with dark brown spots and blotches.
The pear shape of the eggs is an adaptation common to many waders, as it allows for efficient incubation and helps prevent the eggs from rolling away in the simple nest scrape.
The speckled colouration provides excellent camouflage, helping to protect the eggs from predators.
How Long Do Temminck’s Stint Eggs Take To Hatch?
Temminck’s Stint eggs typically take 20 to 22 days to hatch. Both parents share incubation duties.
During this period, the parents take turns sitting on the eggs, carefully regulating the temperature to ensure proper embryo development. The shared incubation allows both parents to maintain their own body condition while providing constant care for the eggs.
As the hatching date approaches, the parents become increasingly attentive, rarely leaving the nest unattended to protect against predators and maintain optimal incubation conditions.
Chicks
The arrival of Temminck’s Stint chicks marks an exciting new phase in the breeding cycle. Let’s examine the key aspects of chick development and care.
How Many Chicks Does A Temminck’s Stint Have?
A Temminck’s Stint pair typically raises 3 to 4 chicks per brood, corresponding to the number of eggs laid.
However, not all eggs may hatch successfully, and some chicks may not survive to fledging due to various factors such as predation or adverse weather conditions.
The parents invest considerable energy in caring for their brood, balancing the needs of individual chicks with the overall survival of the family group.
When Do Temminck’s Stint Chicks Open Their Eyes?
Temminck’s Stint chicks are precocial, meaning they hatch with their eyes open and are capable of leaving the nest within hours of hatching.
This adaptation is crucial for their survival in the open tundra environment. Being able to see and move immediately after hatching allows the chicks to follow their parents to feeding areas and respond quickly to potential threats.
Despite their early mobility, the chicks still rely heavily on their parents for protection and guidance in finding food during their first few weeks of life. The parents use soft calls to communicate with their chicks, guiding them to good feeding spots and warning them of approaching dangers.
This precocial nature is a common adaptation among many wader species.
When Do Temminck’s Stint Chicks Fledge?
Temminck’s Stint chicks typically fledge, or become capable of flight, at around 15 to 18 days after hatching.
The fledging period is relatively short compared to many other bird species, which is an adaptation to the brief summer season in their breeding grounds.
Even after fledging, the young birds may continue to receive some parental care for a short period as they perfect their flying and foraging skills. This rapid development from hatching to fledging is crucial for the species’ survival, allowing the young birds to prepare for their first migration before the onset of autumn.
