Whimbrel Life Cycle: Nest Building To Fledging (and everything in between)
The Whimbrel is a large wading bird well known for its long legs and a bill that curves slightly at the end. Brown on top and white underneath, it shows a striking white ‘V’ shape on its back when in flight.
In this article, we will look into the Whimbrel’s life cycle, including their habitat of choice, nest building, and the stages of chick growth. Keep reading to learn more.

How Long Does A Whimbrel Live?
A Whimbrel usually lives for about 10 years in the wild, but some have been known to live much longer. The longest lifespan recorded for a whimbrel is about 24 years, according to banding data.
How Fast Can A Whimbrel Fly?
During migration, a Whimbrel generally flies at speeds around 52.9 kilometres per hour, or roughly 33 miles per hour. In an extraordinary tracked journey, a whimbrel was noted flying at an average speed of 22 miles per hour over a span of six days. This highlights their endurance at moderate speeds and the ability to adapt for long migrations.
Are Whimbrels Aggressive?
Some aggressive behaviours are displayed by Whimbrels, especially during the breeding season when they protect their nests. If humans or other intruders get too close, these birds may chase them away. This display of aggression can involve both threat postures and physical actions such as dive-bombing or chasing.
Outside the breeding season, whimbrels typically show less aggression, focusing instead on feeding and migration. Still, they can show territorial behaviours, especially when claiming feeding territories.
Various postural displays are also part of whimbrel behaviour, likely linked to social hierarchy within flocks. Bowing, head-bobbing, and bill-tapping are actions thought to signify dominance or submission.
What Is A Whimbrel’s Habitat?
Found primarily in the Arctic tundra, Whimbrels prefer open habitats that range from wet lowlands to dry uplands. Nests are built in these areas, often near the treeline and in sheltered areas like small shrubs or in hummocks.
During the non-breeding season, these shorebirds migrate to various coastal habitats. They are often spotted on beaches, mudflats, and salt marshes, foraging for food. Their winter homes include coastal meadows, estuaries, swamps, and sandy beaches, providing feeding grounds for their survival in this season.
They breed across regions from Greenland and Iceland to northern Scandinavia and Siberia, and winter as far south as Africa and South America.
How Long Does It Take For A Whimbrel To Build A Nest?
It typically takes Whimbrels about 1 to 3 days to build their nests. They build these simple nests as shallow scrapes in the ground, lining them with vegetation like grasses or lichens.
Often, the nests are located on raised spots, such as hummocks or small ridges, which provide better visibility and protection from the wind. The quick nesting process allows Whimbrels to concentrate on incubating and raising their young during the short Arctic summer.
Eggs
Let’s take a look at when Whimbrels lay their eggs, how many they lay, what the eggs look like, and how long they take to hatch.
When Do Whimbrels Lay Eggs?
Whimbrels typically lay their eggs from late spring to early summer, specifically between May and August, depending on their location. This timing helps ensure that the chicks are born during warmer months, which is essential for their growth and survival.
How Many Eggs Does A Whimbrel Lay?
A clutch of Whimbrel eggs usually consists of three to four eggs, although the exact number can change slightly due to local or environmental factors. In some cases, they may even lay as many as five eggs.
What Do Whimbrel Eggs Look Like?
The eggs of the Whimbrel are typically described as bluish-green to olive, often marked with brown splotches and markings. In terms of size, they usually measure about 5.14 to 6.59 cm long and 3.55 to 4.28 cm wide.
How Long Do Whimbrel Eggs Take To Hatch?
Typically, Whimbrel eggs take about 22 to 28 days to hatch. Both parents share this duty, taking turns to keep the eggs warm and protecting them from potential dangers.
Chicks
Let’s take a look at the journey of Whimbrel chicks, from how many hatch to when they first open their eyes and take flight.
How Many Chicks Does A Whimbrel Have?
The number of Whimbrel chicks in a typical brood usually ranges from three to four. This number depends on the number of eggs laid by the female in a clutch, which is generally within this range.
When Do Whimbrel Chicks Open Their Eyes?
Whimbrel chicks are precocial, meaning they are quite mature and able to move around shortly after they hatch. They open their eyes almost right away, which is critical for their survival in the wild. This early stage of development allows them to be alert and responsive to their surroundings from the start.
When Do Whimbrel Chicks Fledge?
Around 35 to 42 days after hatching, Whimbrel chicks usually fledge. They spend the first few weeks in the nest, fully reliant on their parents for food and safety. As they grow, they gain the feathers and strength required for flight.

Frequently Asked Questions
The lifespan of a Whimbrel is typically about 10 years in the wild, though some individuals have been known to live up to 24 years.
Whimbrels display various behaviours, including migration and territoriality. During the breeding season, they can be aggressive in defending their nests, employing both postural displays and physical actions. In non-breeding seasons, they focus on feeding and migrating, showing less aggression but still engaging in territorial behaviours over feeding grounds.
A Whimbrel typically lays a clutch of three to four eggs, although the number can vary slightly due to environmental factors.
Whimbrel eggs are usually bluish-green to olive in colour and are often marked with brown splotches.
