European Storm-petrel Bird Facts (Hydrobates pelagicus)

Visual Identification

Appearance

The European Storm-petrel is a small seabird with predominantly black plumage, slightly browner on the wings. It features a distinctive white rump and a white bar on the underwing, visible in flight. The tail is square-ended with a shallow fork.

They have black legs and feet and dark brown irises. They have a heavy black bill, which is relatively short, with a hooked tip and tubelike nostrils at the base.

Both sexes look alike, although in some Mediterranean populations, females are observed to have a wider tail band and longer wings. However, these differences are impossible to verify from a long distance away.

Their plumage may take on a brownish tinge at later points of the year, but other than that, there are no seasonal plumage differences. Juveniles are similar to adults but may have fresher, darker feathers and less pronounced wing bars.

Distribution

European Storm-petrels inhabit open oceans across the North Atlantic, Mediterranean, and Black Sea. They breed on remote, rocky islands off the coasts of Europe and North Africa, with significant colonies in the UK, Ireland, and Iceland.

During non-breeding seasons, they disperse widely across the Atlantic, reaching as far as the coasts of South America and South Africa. In the UK, they are most commonly seen off western coasts during late summer and autumn.

The Faroe Isles are home to the largest population of breeding storm petrels, with up to 275,000 pairs.

Distribution Map

This map gives you a rough idea of where you might spot a European Storm-petrel. The coloured areas show countries where these birds have been seen.

A few things to keep in mind:

Birds might not be everywhere in the coloured areas, for example, they may be present around the coast of that country
Where birds live can change with seasons and available food
This map is quite simple - it doesn't show exact locations

Bird Attributes Explained

Our bird attributes system rates various aspects of a bird's capabilities on a scale of 0-100, based on data from field observations, scientific studies, and expert knowledge.

Attribute Categories:

Agility: Manoeuvrability, speed, and grace in flight or movement.
Strength: Physical power, often correlating with size and hunting abilities.
Adaptability: Ability to thrive in various environments or changing conditions.
Aggressiveness: Territorial behaviour and assertiveness, particularly during breeding seasons.
Endurance: Stamina, often seen in migration patterns or foraging behaviours.

Understanding the Ratings:

0-20: Very Low
21-40: Low
41-60: Average
61-80: High
81-100: Very High

Remember, these attributes are relative to other bird species and don't necessarily indicate superiority.

Agility 90

Agility

Reflects the bird's manoeuvrability, speed, and grace in flight or movement.

The European Storm-petrel displays remarkable agility with its distinctive flight pattern, fluttering close to the water's surface and making rapid changes in direction. Its ability to 'walk' on water whilst feeding demonstrates exceptional manoeuvrability.

Strength 30

Strength

Indicates the bird's physical power, often correlating with size and hunting abilities.

As a tiny seabird weighing only 20-38 grams, the European Storm-petrel has limited physical strength. However, it possesses enough strength to survive long oceanic journeys and harsh weather conditions.

Adaptability 85

Adaptability

Represents the bird's ability to thrive in various environments or changing conditions.

These birds show high adaptability, thriving in various climates from temperate to tropical zones. Their ability to drink seawater and excrete excess salt, coupled with their long-distance migration capabilities, indicates strong adaptive traits.

Aggressiveness 20

Aggressiveness

Measures the bird's territorial behaviour and assertiveness, particularly during breeding seasons.

European Storm-petrels are not known for aggressive behaviour. Their nocturnal habits at breeding colonies to avoid predation suggest a more evasive than confrontational nature. However, they may display some aggression in defending nesting sites.

Endurance 95

Endurance

Reflects the bird's stamina, often seen in migration patterns or foraging behaviours.

With a lifespan of up to 30 years and the ability to undertake long-distance migrations across vast oceans, the European Storm-petrel demonstrates exceptional endurance. Their capacity to spend most of their lives at sea in varying conditions further supports this high endurance rating.

Diet

European Storm-petrels feed primarily on small fish, squid, jellyfish, and zooplankton. They often follow ships to feed on disturbed marine life and discarded offal. These birds have a keen sense of smell, which they use to locate food sources across vast ocean expanses.

Fluttering bat-like flight is another helpful factor in identifying a storm petrel – when feeding, they patter across the surface of the waves with their wings held in a V position.

Behaviour

European Storm-petrels are highly pelagic, spending most of their lives at sea. They have a distinctive flight pattern, fluttering close to the water's surface with rapid wing beats, often appearing to 'walk' on water as they pick food items.

These birds are typically nocturnal at breeding colonies to avoid predation.

Vocalisation

At sea, European Storm-petrels are a silent species, but at breeding colonies, they produce a variety of calls. The most common is a purring 'purr-r-r-r-r' sound, often given in flight. They also make a witch-like cackling 'hee-hee-hee' when in their burrows.

These vocalisations are typically heard at night when the birds are most active at their nesting sites.

Nesting & Breeding

Breeding occurs in loose colonies on remote, rocky islands. Pairs form long-term bonds and return to the same nesting site each year. The breeding season typically starts in late spring or early summer.

Nests are built in crevices, burrows, or under rocks, often lined with a few feathers or grass. Females lay a single white egg, sometimes with a faint ring of reddish specks.

Both parents share incubation duties for about 40 days. The chick is fed by both parents and fledges after 56-86 days, becoming independent soon after leaving the nest.

Conservation and Status

Global Conservation Status

Least Concern ^[1]

While currently listed as Least Concern, European Storm-petrels face threats from introduced predators at breeding sites and marine pollution.

Conservation efforts focus on protecting breeding colonies, particularly on small islands, and reducing plastic pollution in their feeding areas.

Did You Know?

European Storm-petrels can live for over 30 years, making them one of the longest-lived small seabirds.
They can drink seawater and excrete excess salt through special glands near their nostrils.
These birds were once known as 'Mother Carey's Chickens' by sailors, who considered their presence a sign of impending bad weather. ‘Mother Carey’ was the name given to a mythical sea witch in 19th-century folklore.

FAQs

Why are they called storm petrels?

The word ‘petrel’ is thought to have derived from the species’ ‘pitter-pattering’ stepping movements across the surface of ocean waves.

Another explanation, that the name has links to St Peter, due to stories that tell of his ability to walk on water, have been added at a later stage.

‘Storm’ comes from these small seabirds having a reputation for being able to withstand spells of severe weather at sea and frequently being spotted ahead of the arrival of major storms.

What is the superstition about storm petrels?

Storm petrels were seen by some to forecast death, due to their association with severe storms and bad weather at sea. Sightings of storm petrels were viewed as a bad omen by most sailors.
