Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Adults have a grayish-brown body plumage, darker on the back and lighter on the flanks. The most distinctive feature is the prominent white patch at the base of the bill, which gives the species its name. The belly is marked with irregular, broad black bars, which become more extensive with age. The undertail coverts are white. The wings are dark brown with lighter coverts, and the tail is dark with white outer feathers.

2. 2

   Beak shape

   Shape and color of the bill: a key field mark.

   Relatively short and stout, pinkish-orange with a white nail. The white frontal patch extends from the base of the bill to the forehead.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown

4. 4

   Leg color

   Leg and foot color.

   Bright orange

5. 5

   Distinguishing features

   Standout features that separate this species.

   The combination of the white frontal patch at the base of the bill, the pinkish-orange bill, and the black barring on the belly are key diagnostic features for adults. Juveniles lack the white frontal patch and belly barring.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles are duller overall, lacking the white frontal patch and the black belly barring. Their bill is grayish-pink, and their legs are dull orange. The white frontal patch and belly barring develop during their first winter.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   No significant seasonal plumage changes in adults, other than the gradual increase in black belly barring with age. Juveniles acquire adult characteristics during their first winter.

8. 8

   Sexual dimorphism

   How males and females differ.

   Males (ganders) and females (geese) are generally monomorphic in plumage, though ganders tend to be slightly larger than geese.

Key field marks

• White Frontal Patch. Look for the distinct white patch at the base of the bill, extending onto the forehead. This is present in adults and develops in juveniles during their first winter.
• Black Belly Barring. Observe the irregular, broad black bars on the belly. These are more extensive in older individuals and absent in juveniles.
• Bill Color. Note the pinkish-orange bill color. This contrasts with the darker bills of some other goose species.
• Leg Color. Identify the bright orange legs, a consistent feature in adults.
• Vocalization. Listen for the characteristic 'laughing' call, a high-pitched 'wah-wah-wah' or 'kow-lyow-lyow', which is very distinctive.
• Size and Shape. It's a medium-sized goose, larger than a Cackling Goose but smaller than a Canada Goose, with a relatively compact body.
