Fulmar Life Cycle: Nest Building To Fledging (and everything in between)
Greyish-white feathers and stiff wings make Fulmars distinct as they glide gracefully over the sea. Their unique flight style, with white underparts and greyish backs, makes them stand out.
In this article we’ll take a closer look at the Fulmar’s journey, from the start of nest building to the nurturing of their eggs, and how their chicks develop before leaving the nest. Keep reading to learn more.

How Long Does A Fulmar Live?
The Fulmar has an impressive lifespan for a seabird. Their average lifespan is typically estimated at 31 years, with some individuals reaching an impressive 51 years in the wild.
How Fast Can A Fulmar Fly?
At an average of 47 kilometres per hour (around 29 miles per hour), the Fulmar’s flight speed is perfectly suited to the sea. They glide with stiff wings, and their quick wingbeats make it easy to travel across the waves.
Are Fulmars Aggressive?
Aggressive behaviour is often seen in Fulmars, particularly at their nesting sites. These seabirds have a range of vocal and visual tactics they use to show aggression. They might “cackle” or “bray” at varying speeds to warn off intruders or to defend their nests. Their physical displays can include raising their wing, charging at other birds, and even pushing them to establish dominance.
One of the most striking defensive behaviours is their ability to spit a foul smelling stomach oil. This oil not only discourages predators but can also affect the waterproofing and flight capabilities of avian threats, posing a significant risk to them.
What Is A Fulmar’s Habitat?
The Fulmar is mostly found in the open ocean, moving across the northern Atlantic, Pacific, and Arctic Oceans. These seabirds are specially adapted to life over deep waters, where they feed and spend most of their time.
During the breeding season, they can be found in large groups on cliffs in the subarctic and Arctic regions. Fulmars nest in places ranging from the high Arctic to temperate zones, often on cliffs and islands. Their habitats extend from areas close to pack ice in the Arctic to milder oceanic waters, showing their adaptability.
How Long Does It Take For A Fulmar To Build A Nest?
The nests of Fulmars are generally simple. They create a basic scrape on a rock ledge or a shallow depression on the ground, sometimes adding small stones or bits of vegetation. This minimalistic process can take anywhere between a few hours to a few days depending on the location and materials used.
For example nests built on grass take significantly less time to create than those built on sand. Both the male and female take part in the nest preparation.
Eggs
Here’s everything you need to know about Fulmar eggs, including when they are laid, how many there are, and how long they take to hatch.
When Do Fulmars Lay Eggs?
The Fulmar starts its breeding season in late spring, with egg laying occurring mainly in May to early June.
How Many Eggs Does A Fulmar Lay?
Fulmars lay only one egg per season, which is common among seabirds that breed in tough environments. By laying only one egg, the parents can concentrate all their energy on raising that single chick.
What Do Fulmar Eggs Look Like?
The eggs of a Fulmar are mostly white and usually measure 74 mm by 51 mm (roughly 2.9 inches by 2 inches).
How Long Do Fulmar Eggs Take To Hatch?
The incubation period for Fulmar eggs typically lasts between 47 and 54 days. This allows both parents to take turns incubating, which is critical for the chick’s survival in the challenging environments these birds breed in.
Chicks
Let’s take a look at what happens in a Fulmar chick’s life, from how many are raised to when they are ready to leave the nest.
How Many Chicks Does A Fulmar Have?
Typically, Fulmars raise only one chick per season. Each pair lays just one egg, and after incubation, which both parents take part in, they direct all their energy towards ensuring the chick’s survival.
When Do Fulmar Chicks Open Their Eyes?
Fulmar chicks are altricial, meaning they are born completely dependent on their parents. Their eyes remain closed at birth and only open after a few days.
When Do Fulmar Chicks Fledge?
It takes about 70 to 75 days for Fulmar chicks to fledge. During this period, they grow and learn how to survive independently, with both parents continuing to care for and protect them until they are ready to leave the nest.
