How to identify the Pied Avocet

To correctly identify the Pied Avocet (Recurvirostra avosetta), check each of these features. Birds can be tricky: habit, habitat, and call often confirm a sighting that a single photo cannot.

Size at a glance

Length

42-45 cm (16.5-17.7 in)

Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Adults have a pristine white body with bold black markings. These include a black cap extending from the bill to the nape, two broad black stripes on the back, and black primary and secondary flight feathers. The underparts are pure white.

2. 2

   Beak shape

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

   Long, slender, and distinctly upcurved, black in color. This unique shape is adapted for its specialized feeding method.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown, almost black.

4. 4

   Leg color

   Leg and foot color.

   Long, slender, bluish-grey legs and feet.

5. 5

   Distinguishing features

   Standout features that separate this species.

   The combination of its pied black and white plumage, long bluish-grey legs, and especially its unique upcurved bill makes it unmistakable. In flight, the long legs trail behind the tail, and the black and white wing pattern is prominent.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles resemble adults but have a duller, browner tinge to the black markings, particularly on the head and back. The black areas may appear more greyish-brown, and the white plumage might be less pristine.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   There are no significant seasonal plumage changes in adults. Breeding and non-breeding plumages are essentially identical.

8. 8

   Sexual dimorphism

   How males and females differ.

   Males and females are generally monomorphic in plumage, though females may appear slightly smaller and have a slightly less pronounced bill curvature. These differences are subtle and not reliable for field identification.

Key field marks

• Plumage. Look for the striking black and white pattern: pure white body, black cap, and two prominent black stripes on the back. Black primary and secondary flight feathers are visible in flight.
• Bill Shape. The long, slender, and distinctly upcurved black bill is the most unique and defining feature, used in its characteristic sweeping feeding motion.
• Legs. Observe the long, slender, bluish-grey legs, which extend well beyond the tail in flight.
• Behavior. Watch for its distinctive feeding behavior: wading in shallow water and sweeping its bill from side to side. Often seen in flocks.
• Call. Listen for its clear, repeated 'kluit' or 'klooit' call, especially when disturbed or in flight.
