Seagull

A seagull is a common informal name for a gull, a seabird in the family Laridae.

Updated July 30, 20261 min readCited sources

A seagull is the common informal name for a gull, a seabird in the family Laridae. The term has no fixed taxonomic meaning and is used broadly for several gull species, especially those near coasts and waterways.

What it is

Seagull is a layperson’s term for gulls, not a formal scientific classification. Gulls belong to the family Laridae and subfamily Larinae, in the order Charadriiformes. Ornithologists generally prefer “gull” over “seagull.”

Key details

Gulls are medium to large seabirds with webbed feet, long wings, and plumage that is typically white, grey, or dark-backed. They are opportunistic feeders, eating fish, crustaceans, carrion, and human food waste. Gulls are highly adaptable and live along coasts, inland waterways, and urban areas.

Why it matters

Gulls are common across Canada’s Atlantic, Pacific, and Arctic coasts, as well as around the Great Lakes and major urban waterfronts. Their adaptability and scavenging habits make them familiar birds in coastal cities and ports, often interacting with human environments.

In short

  • Seagull is an informal name for gulls, not a scientific term.
  • Gulls are adaptable seabirds found on coasts and inland areas.
  • They are opportunistic feeders, often scavenging near humans.
  • In Canada, gulls are common along all three coasts and the Great Lakes.

Quick questions
