Uccelli simili a Swan Goose

Key differences

The Swan Goose has a longer, more slender neck, a dark bill (vs. orange in Greylag), and a distinct dark stripe down the back of the neck. Greylag Geese lack the sharp contrast between dark hindneck and pale foreneck.

Key differences

Bean Geese have a shorter, thicker neck, and their bill is typically black with an orange band (though variable). They lack the distinct dark neck stripe and the white line at the bill base of the Swan Goose.

Key differences

Domestic forms often have a prominent knob at the base of the bill (especially males), are generally larger and heavier, and come in various color morphs (e.g., all white). Wild Swan Geese are uniformly patterned and lack the prominent knob.
