Larus argentatus
A large, familiar gull with a bright red bill-spot.
Size: 54-60 cm | Habitat: Pond, Lake & River Birds | Season: All year
The classic large 'seagull' of British seaside towns, the herring gull has a pale grey back, white body, black wingtips, and pink legs, with a heavy yellow bill marked by a red spot near the tip. Increasingly found well inland, from reservoirs to rubbish tips and rooftops.

Herring gulls are bold, adaptable, and highly opportunistic, scavenging from bins, following boats and ploughs, and increasingly nesting on flat rooftops in towns. Chicks peck at the red bill-spot to prompt a parent to regurgitate food.
A chick's instinct to peck at its parent's red bill-spot for food is so strong that even a simple painted stick with a red dot can trigger the same feeding response — a classic discovery in animal behaviour science.
The Herring Gull (Larus argentatus) is the archetypal "seagull" of British seaside towns: a large, pale grey-backed gull with black, white-spotted wingtips, pink legs, and a heavy yellow bill marked with a red spot.
Herring gulls are bold, resourceful, and highly opportunistic, scavenging from bins, following fishing boats and ploughs, and increasingly nesting on flat urban rooftops where they can raise chicks safely away from ground predators — a striking behavioural shift from their traditional coastal cliff colonies. Chicks instinctively peck at the red spot on a parent's bill to trigger feeding, one of the most famous examples in the study of animal behaviour.
Understanding the herring gull reveals a genuine conservation paradox: a bird that feels overwhelmingly common in daily life around coastal towns can still be in serious national decline, because visible urban success doesn't necessarily reflect the health of the wider breeding population.
🔴 Conservation status: Red (UK Birds of Conservation Concern 5)
Red-listed. Despite being one of the most familiar and vocal gulls in British towns, the herring gull's true breeding population has fallen by more than half since the 1970s, largely due to declining food availability at sea and reduced breeding success at traditional coastal colonies. Its Red-listed status is a reminder that a bird can seem abundant in daily life around bins and rooftops while its wider population is in real trouble.
