Spoon-billed Sandpiper vs Grey-crowned Yellowthroat

In short

The Spoon-billed Sandpiper is a small wader with a distinctive spatula-shaped bill, while the Grey-crowned Yellowthroat is a passerine with a more typical warbler appearance and a grey crown. These species differ significantly in structure and habitat preferences, making them unlikely to be confused in the field.

Identification tips

1. Look for the spatula-shaped bill of the Spoon-billed Sandpiper, a unique feature among sandpipers. 2. Note the habitat: mudflats for the sandpiper versus scrub and savannas for the yellowthroat. 3. Observe plumage: rufous tones in breeding Spoon-billed Sandpipers versus the grey crown and yellow underparts of the Grey-crowned Yellowthroat. 4. Listen for vocal differences: sandpiper calls versus warbler songs.

Size

The Spoon-billed Sandpiper is a small shorebird, while the Grey-crowned Yellowthroat is a small songbird, generally larger and more robust.

Plumage

Spoon-billed Sandpipers in breeding plumage have vibrant rufous tones on the face and upperparts, whereas Grey-crowned Yellowthroats have a grey crown and yellow underparts. In non-breeding plumage, the sandpiper is paler gray, which is distinct from the yellowthroat's consistent coloration.

Behaviour

Spoon-billed Sandpipers are often seen foraging in mudflats, while Grey-crowned Yellowthroats are more likely to be found in shrubs and savannas, often seen flitting through vegetation.

Habitat

Spoon-billed Sandpipers are typically found in coastal mudflats and estuaries, whereas Grey-crowned Yellowthroats inhabit semi-arid scrub, savannas, and lowland fields, sometimes up to 2000 m elevation.

Voice

The vocalizations of these species are quite different, with the Spoon-billed Sandpiper having typical sandpiper calls and the Grey-crowned Yellowthroat producing warbler-like songs.
