Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Overall rufous-brown to buffy-brown, heavily streaked and mottled with dark brown or black. The underparts are paler, buffy-white, with prominent dark brown streaking and fine barring. The facial disc is well-defined, rufous-brown, bordered by dark brown. Prominent, widely spaced ear tufts are dark brown with buffy edges.

2. 2

   Beak shape

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

   Strong, hooked, and dark grey to black.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Bright orange-yellow to deep orange.

4. 4

   Leg color

   Leg and foot color.

   Feathered down to the toes, which are dark grey with black talons.

5. 5

   Distinguishing features

   Standout features that separate this species.

   Large size, prominent ear tufts, bright orange-yellow eyes, and heavily streaked plumage. The dark malar stripe (moustache) is also a key feature.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Similar to adults but often with softer, fluffier plumage, less distinct markings, and sometimes paler eyes. Ear tufts may be less developed.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   No significant seasonal plumage changes.

8. 8

   Sexual dimorphism

   How males and females differ.

   Females are generally slightly larger and heavier than males, but plumage is identical.

Key field marks

• Size and Shape. Look for a large, robust owl with a powerful build and prominent ear tufts that are held erect.
• Plumage Coloration. Observe the overall rufous-brown to buffy-brown plumage with heavy dark streaking and mottling. The underparts are paler with distinct dark streaks and fine barring.
• Eye Color. Note the striking bright orange-yellow to deep orange eyes, which are a key diagnostic feature.
• Facial Disc. Identify the well-defined rufous-brown facial disc, often bordered by a darker rim, and the prominent dark malar stripe (moustache).
• Ear Tufts. The large, widely spaced, and often erect ear tufts are a crucial identification mark, distinguishing it from other large owls without such prominent tufts.
• Vocalization. Listen for its deep, resonant 'hoo-hoo-hoo' call, especially at dusk or dawn.
