The Buff-necked Ibis is a South American ibis with a long downcurved bill and a pale buff neck. It forages in open grassland; in Valle del Cauca, Colombia, arthropods including insects formed much of its diet.
It has a pale buff neck, a long down-curved bill and pink legs.
It walks through open areas while foraging. A study in Colombia found arthropods and insects among its main prey and recorded roosting in palms.
It is usually found in pairs or small groups in open habitats such as pastures and savannas, often foraging far from water.
The back and wings are mostly grey, contrasting with the black belly and buff head and neck.
Males and females look alike, and it flies with its neck extended.
