Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Adults have pristine white underparts, head, and tail, with pale grey upperparts. The most distinctive feature is the prominent black patch on the leading edge of the underwing and the 'shoulder' (carpal joint) on the upperwing. The primary flight feathers are dark grey to black, contrasting with the paler grey upperwing coverts. The tail is square-tipped and white.

2. 2

   Beak shape

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

   Small, sharply hooked black beak with a yellow cere.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Bright red eyes, set in a black facial mask that extends from the eye to the beak.

4. 4

   Leg color

   Leg and foot color.

   Bright yellow legs and feet.

5. 5

   Distinguishing features

   Standout features that separate this species.

   Bright red eyes, prominent black 'shoulders', and a distinctive hovering flight. The white underparts and pale grey upperparts are key.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles have a brownish wash on the head and breast, with rufous-brown mottling on the upperparts and wing coverts. The black shoulder patches are present but may be less sharply defined. The eyes are initially yellowish-brown, gradually turning red with age.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   No significant seasonal plumage changes. Plumage remains consistent year-round.

8. 8

   Sexual dimorphism

   How males and females differ.

   Males and females are generally similar in plumage and size, though females may be slightly larger on average.

Key field marks

• Plumage. Look for the stark contrast of pure white underparts and head against pale grey upperparts. The most crucial mark is the prominent black patch on the 'shoulder' (carpal joint) of the upperwing and the leading edge of the underwing.
• Eyes. The bright red eyes are a key identifier, especially in adults, contrasting with the black facial mask.
• Flight Style. Observe its characteristic hovering flight, often facing into the wind, with rapid wing beats. It will often drop silently onto prey.
• Size and Shape. A relatively small, slender raptor with long, pointed wings and a short, square tail. Appears very elegant in flight.
• Legs and Feet. Bright yellow legs and feet are visible when perched or in flight.
