Definition
The Andean lapwing (Vanellus resplendens), also known as the resplendent lapwing, is a medium-sized wading bird belonging to the family Charadriidae. It inhabits the high‑altitude grasslands and puna ecosystems of the central Andes in South America.
Overview
The species is distributed across the Andean regions of Peru, Bolivia, northern Chile, and northwestern Argentina, typically at elevations between 2,500 and 4,500 m. It favors open, often semi‑arid grasslands, dry lakeshores, and agricultural fields where it forages on the ground for insects, arachnids, and other small invertebrates. The Andean lapwing is largely sedentary, though local movements may occur in response to seasonal changes in temperature and food availability.
Etymology / Origin
- Andean: Refers to the Andes mountain range, the primary geographical range of the species.
- Lapwing: The common English name for birds of the genus Vanellus, derived from Old English lēapewince (“leaping winch” or “leaping bird”), reflecting the bird’s characteristic erratic, leaping flight.
- Scientific name Vanellus resplendens: The genus name Vanellus is Latin for “lapwing”. The specific epithet resplendens means “shining” or “splendid”, alluding to the bird’s bright plumage.
Characteristics
- Size: Approximately 30–35 cm in length; wingspan 60–70 cm.
- Plumage: Adults display a striking contrast of dark slate‑gray upperparts, a white throat and breast, and bold black facial markings. The belly and vent are white, while the under‑wing coverts are iridescent green‑blue. In flight, the wings show a conspicuous white trailing edge and a narrow black band.
- Sexes: Male and female plumage are similar; juveniles are duller, with brownish tones on the head and back.
- Vocalizations: A harsh, repetitive “kik‑kik‑kik” call, often given while the bird is perched on a rock or low branch.
- Behavior: Typically found singly or in loose pairs; sometimes forms small flocks with other lapwing species during migration or at abundant feeding sites. It is known for a characteristic “run‑and‑stop” foraging style, punctuated by sudden, short flights.
- Reproduction: Breeding occurs during the austral summer (October–January). Nests are simple scrapes on the ground, lined with vegetation. Clutch size is usually 2–3 eggs, which are cryptically colored. Both parents share incubation duties and care for the chicks, which are precocial and leave the nest shortly after hatching.
