Threskiornis spinicollis


60-75 cm. Dark wings with an iridescent sheen in sunlight, dark back and collar. White neck, white underparts and undertail, long, black, downcurved bill, legs are usually red near the top and dark grey toward the feet. Straw-like feathers on the neck of adults. Sexes are similar; males have longer bills and females have a dark band across their upper breast. Juveniles have duller colours, shorter bills with less curvature, and lack the straw-like plumes on the neck.

  • Diet: Includes aquatic insects, molluscs, frogs, and food sifted from the surface of the water, grasshoppers, crickets, and locusts.
