What Do Great Skuas Look Like? (how to identify them)

Great Skuas, with their scientific name Stercorarius skua, are formidable seabirds, roughly the size of a herring gull. They have a robust build and sport a predominantly dark plumage with striking white wing flashes visible in flight. 

Adults are streaked greyish brown with a black cap, whereas juveniles are warmer brown without streaking below. Their powerful flight and short, blunt tail make them easily distinguishable.

Differences Between Male And Female Great Skuas

Males and females are similar in appearance, though females are typically a bit larger. Juveniles, in contrast, lack the adults’ streaking and are darker overall.

What Do Great Skuas Eat?

Great Skuas are opportunistic feeders with a varied diet, including fish, carrion, and other birds like Puffins. They are known for their aggressive piracy, often stealing food from other seabirds mid-flight and even preying on lambs or pony foals. 

Their ability to scavenge from fishing vessels also plays a significant role in their diet.

Where Do Great Skuas Live? (inc. migration info)

Breeding primarily in Iceland, Norway, the Faroe Islands, and the Scottish islands, Great Skuas are migratory birds. They spend winters in the Atlantic Ocean, ranging from the coasts of Spain and Africa to North American waters. 

During migration, their presence is especially notable off the southwestern coasts of the UK.
