The petrel bird is a master of flight, using air currents above the waves to soar for thousands of miles.
The "Storm Bird"
The petrel is a seabird that never fails to captivate me. People often call it the "storm bird," and once you've seen one in action, you'll understand exactly why - these incredible creatures have this almost magical ability to dance with the fiercest waves and howling winds, as if they were born to embrace the ocean's wildest moods.
What's fascinating is that this single name actually encompasses dozens of species from the Procellariidae family - all pelagic birds that have made the vast open ocean their permanent home. What truly amazes me about petrels is their remarkable resilience and how perfectly they've adapted to thrive in one of Earth's most challenging environments. They're not just birds; they're living embodiments of the ocean's untamed spirit.
How to Identify a Petrel
Although species vary in size and color, all petrels share a unique feature: they are "tubenoses".
The most reliable identification feature is their bill. It is topped with two tubes that serve as nostrils. This remarkable structure is connected to a special gland that allows them to filter and expel excess salt from the seawater they ingest. If you see a seabird with this "tube" on its bill, it's a member of the Procellariiformes order (petrels, albatrosses, shearwaters).
The key feature of the petrel bird: tubular nostrils that allow it to process salt from the sea.
Our Ornithologist's Advice
By the Les-Oiseaux.com team, published on June 17, 2025
My advice: for the petrel, swap your binoculars for your ears and daylight for darkness. The most memorable experience is auditory, not visual. Unlike noisy, daytime seabird colonies, the petrel lives a life of stealth. To avoid predators like gulls, most petrels only return to their nests—often in burrows—under the cover of night.
If you're ever near a breeding colony, listen carefully after dusk. You'll hear strange, haunting, and mesmerizing calls rising from the ground. It’s an almost mystical atmosphere, a secret concert that reveals the true nature of this ghost of the oceans. An unforgettable experience!

Petrel vs. Puffin: Don't Confuse Them!
The Petrel is sometimes confused with the Atlantic Puffin, but they are very different. Here's how to tell them apart:
Petrel
Silhouette: Slender, with long, thin wings.
Beak: Dark and thin, with visible nostrils in a tube on top.
Flight: Effortless, acrobatic gliding, often low over the waves.
Family: Procellariiformes (Tubenoses).
Atlantic Puffin
Silhouette: Stocky and compact, like a "flying football".
Beak: Thick, triangular, and brightly colored during breeding season.
Flight: Direct and whirring, with very fast wing beats.
Family: Alcidae (Auks).
Habitat and Distribution
Petrels are found in every ocean in the world, from the Arctic to the Antarctic. They are the epitome of the pelagic bird: they only come ashore to breed, choosing remote islands and inaccessible cliffs to stay safe from land predators. The rest of the year, their home is the vastness of the ocean.

Flight and Behavior
The petrel's behavior is as unique as its anatomy. It practices dynamic soaring, using the energy from winds deflecting off the waves. This allows it to travel thousands of miles with very little energy expenditure.
The smaller species, like the Storm Petrel, are famous for their feeding technique: they hover into the wind, pattering on the water's surface with their feet to stir up plankton, which gives them the appearance of dancing or walking on water.
Conservation Status: A Threatened Group
The petrel family is one of the most threatened bird groups in the world. Their ground-nesting habits make them extremely vulnerable to invasive species (rats, cats) introduced to their breeding islands. They are also victims of accidental capture by fishing gear (longlines) and plastic ingestion.
Frequently Asked Questions (FAQ)
Why do petrels have a "tube" on their beak?
This tube houses their nostrils and is connected to a salt gland. It allows them to drink seawater and excrete the salt as concentrated saline droplets, a vital adaptation for a bird that spends its entire life at sea.
Why are they called "storm birds"?
This nickname comes from ancient sailors who often observed them before or during bad weather. In reality, petrels don't cause storms, but their ability to navigate strong winds allows them to remain active when other birds are grounded.
Do petrels have a good sense of smell?
Yes, and it's exceptional for a bird! Their large nasal passages give them an excellent sense of smell, which they use to locate schools of krill or other food sources from miles away across the vast ocean.
