The Herring Gull: The Classic 'Seagull' of Our Coasts
The Herring Gull (Larus argentatus), a robust and intelligent bird, is the quintessential coastal icon.
A Powerful and Charismatic Bird
You really can't overlook this guy when he makes an appearance! The Herring Gull (Larus argentatus) is the quintessential seaside tough guy—one of those birds that truly owns the scene. With his confident swagger, that piercing gaze that could slice through glass, and that loud call echoing from miles away across the harbors, he certainly knows how to make an entrance. But how often have you heard someone just refer to him as a "seagull"? That's a big mistake! This feathered powerhouse has a lot more going on in that head of his than his reputation for raiding trash would lead you to believe—his intelligence will genuinely astonish you.
How to Identify a Herring Gull
Identifying an adult Herring Gull is fairly straightforward if you focus on a few key features:
Size: It's a large, very robust bird, measuring about 24-26 inches (60-66 cm) long. It is visibly much larger and bulkier than a Black-headed Gull.
Bill: Its bill is yellow, thick, and powerful, with a very clear, bright red spot on the lower mandible. This is one of its most distinctive marks.
Legs: Its legs are thick and flesh-pink in color.
Eyes: It has a light, pale-yellow eye, giving it an intense, piercing stare.
Plumage: Its back and the tops of its wings are a medium grey ("herring" grey), contrasting with the pure white of its head and underparts. The wingtips are black with white spots.
The Secret of the Red Spot on its Bill
That famous red spot is not just for decoration. It plays a crucial role during the breeding season. It acts as a visual stimulus for the chicks. Hungry chicks instinctively tap this spot with their own bills, which triggers a regurgitation reflex in the parent, who then provides them with food. It is a fascinating example of innate communication in the animal world.
The red spot serves as a "button" that chicks press to ask for their meal.

The Herring Gull is primarily a coastal bird. It is found on rocky shores, beaches, fishing harbors, and estuaries. However, its incredible adaptability has led it to colonize further inland, following rivers and even nesting on city rooftops, where it finds food and safety.
Diet: A Formidable Opportunist
The Herring Gull is an omnivore with strong predatory tendencies. It feeds on fish, crabs, mollusks (which it drops from a height to break their shells), and the eggs and chicks of other birds. It is also an effective scavenger and will not hesitate to exploit human resources: garbage in landfills, picnic leftovers, or fish discarded by fishing boats.
Conservation Status
The Herring Gull is a common species, listed as "Least Concern" (LC) by the IUCN. Its populations have expanded for a long time, thanks in part to its ability to profit from human activities. Locally, this cohabitation can sometimes create conflicts, especially in urban environments due to noise and property damage.
