Habitat Comparison
Pink-footed Goose
Breeds on tundra and cliff ledges in Greenland, Iceland, and Svalbard. Winters on agricultural fields, saltmarshes, and estuaries in Scotland, England, Netherlands, and Denmark.
Blue-billed Teal
Freshwater lakes, marshes, pans, and flooded grasslands across sub-Saharan Africa from Senegal and Sudan south to the Cape. Nomadic; follows seasonal rains. Common but easily overlooked among reed beds.
Song & Call Comparison
Pink-footed Goose
A musical, high-pitched 'wink-wink' — noticeably higher and more musical than Greylag or Bean Goose. The 'wink' call is a reliable identification feature in winter flocks.
Blue-billed Teal
Male utters a soft, teal-like peep; female gives a muted quack. Pairs call quietly in dense papyrus; soft contact calls help birds maintain proximity in thick African marsh vegetation.
Geographic Range & Migration
Pink-footed Goose
Breeds on Arctic and sub-Arctic tundra ponds across North America; winters on both US coasts and Gulf Coast estuaries.
Blue-billed Teal
Breeds in Arctic and subarctic Eurasia; winters at sea in the North Atlantic and from western Europe to eastern Africa.

About These Birds
Pink-footed Goose
A compact short-necked goose with a pink-and-black bill, pink feet, and warm brown-grey body. Breeds in Greenland, Iceland, and Svalbard; winters in northwestern Europe. One of Britain's most spectacular winter visitors; massive roosts of over 200,000 birds occur in Scotland.
Blue-billed Teal
A small dark teal with blue-grey bill and legs, brown-streaked plumage, and fine pale spotting on the flanks. The most widespread teal in sub-Saharan Africa. Found on freshwater lakes and marshes. Highly nomadic; follows seasonal rainfall. Swims low in the water like a pochard.
