Taxonomy and systematics

The Andean lapwing was originally described as ''Charadrius resplendens'' and has sometimes been placed in genus ''Ptiloscelys''. It is monotypic.

Description

The Andean lapwing is about long and weighs . The sexes are alike and have no seasonal changes in plumage. Adults have a creamy gray head and neck with a dark brownish gray patch around the eye. Their upperparts are bronzy green with a purple patch on the wing coverts. Their breast is dark gray and their belly white. Their bill is pinkish orange with a black tip, their eye is reddish, and their legs are also reddish. Juveniles have a brownish head and neck, buff mottling on the breast, and pale buff fringes on the upperparts feathers.Wiersma, P. and G. M. Kirwan (2020).

Distribution and habitat

The Andean lapwing is found in the Andes from southwestern Colombia south through Ecuador, Peru, and Bolivia into northern Chile and northwestern Argentina. It inhabits a variety of open landscapes including ''páramo'' and '' puna'', shore meadows, and open parts of marshes. It is usually found near lakes or rivers but shuns saline waters. In general it ranges between of elevation but is found as high as in Chile and as low as in the southern parts of its range. It occasionally reaches the coast during the austral winter.

Behavior

Movement

The Andean lapwing is essentially resident in most of its range but moves to lower elevations during the austral winter.

Feeding

Nothing is known about the Andean lapwing's foraging techniques or its diet.

Breeding

The Andean lapwing's breeding season is mostly between October and December though occasionally it may extend to February. One nest was a depression in the ground lined with plant material including lichens. The clutch size is three or four. The incubation period and time to fledging are not known.

Vocalization

Like most lapwings, the Andean is noisy. " ually heard are a sharp 'wik' in alarm, a harsh 'criee-criee-cri' call, a staccato 'cwi-cwi-cwi...' or more mellow and melodic 'dididi---celeec-celeec-celeec-ce...'." It also makes "a soft querulous 'cow' note...or a low, tremulous 'kwiwiwiwirrr'."

Status

The IUCN has assessed the Andean lapwing as being of Least Concern. It has a large range, and its estimated population of under 6700 mature individuals is believed to be stable. No immediate threats have been identified. "Occupation of bleak high-altitude habitats with relatively low densities of humans suggests hat thespecies is probably secure at present."
