Lesser Black-Backed Gull

Fascinating facts about the Lesser Black-Backed Gull

• In the 1950s, fewer than 1,000 pairs of lesser black-backed gulls nested in Britain. Today there are over 300,000. This explosion happened because they learned to eat our garbage — a 70-year population recovery driven entirely by human waste and the birds' willingness to change their diet from fish to landfill.
• A lesser black-backed gull from Iceland can reach North America in under two weeks, crossing 2,000 km of open ocean in a single flight. They don't memorize routes or follow landmarks. Instead, they navigate by polarised light patterns in the sky — a biological compass so precise it works on cloudy days when the sun is below the horizon.
• Watch a lesser black-backed gull on a beach and you'll see it stamp its feet in shallow water. This looks like restless dancing, but it's actually hunting. The stamping tricks small fish and crustaceans into thinking a storm is coming and they surface in panic — straight into the gull's beak.
• The darker your gull's back, the higher its rank in the colony. Lesser black-backed gulls have pitch-black backs, making them visually dominant over paler cousins like herring gulls. In mixed-species feeding groups, a darker back acts like a uniform — other birds yield their food without a fight, just from the color alone.
• A lesser black-backed gull can live 30 years in the wild, and one individual ringed in 1969 was still alive in 2000. Over three decades, a single bird might raise 60 chicks across 30 breeding seasons. These long-lived scavengers are now so abundant in European cities that they've become the top predator on some urban rooftops — a role filled by hawks just 50 years ago.

About the Lesser Black-Backed Gull

As the tide ebbs and flows, the Lesser Black-Backed Gull dances along the shoreline, its agile form weaving in and out of the waves with an effortless elegance, its slate-grey feathers glistening like polished stone in the sunlight. With a piercing cry, it takes to the skies, its wings beating in a powerful, slow rhythm as it soars overhead, scanning the waters below for the telltale signs of its next meal. In its mastery of the coastal realm, this gull embodies a perfect harmony of grace and opportunism, a true monarch of the marine fringe.
