In short

The Pied Avocet and Curlew Sandpiper can be distinguished primarily by their bill shape and plumage patterns. The Avocet has a distinctively upturned bill and striking black and white plumage, while the Curlew Sandpiper features a slightly decurved bill and more muted, often reddish tones during breeding season.

Identification tips

Plumage: Note the Avocet's bold black and white pattern against the Sandpiper's more subdued tones. 3. Size: Avocets are larger and more robust. 4. Behavior: Observe feeding behavior; Avocets sweep their bills, Sandpipers probe. 5. Habitat: Consider the habitat; Avocets prefer saline wetlands, Sandpipers are often on mudflats.

Size

The Pied Avocet is larger and more robust compared to the smaller, more delicate Curlew Sandpiper.
