rusthalslo Oreopholus ruficollis

Handsome and distinctive plover of windswept open grasslands and sandy dunes from Patagonian steppe to the high Andes; also ranges to agricultural fields, mainly during migration and winter. Mostly uncommon and often rather local. Usually found as pairs or small groups, running well and blending in easily with its grassy steppe habitat. Note the elegant, tall-standing posture, bold face pattern, straight pointed bill, bright rusty throat, and striped back. No similar species.
