The Least Seedsnipe (Thinocorus rumicivorus) is a truly unique member of the order Charadriiformes, often referred to as the 'shorebird that thinks it's a finch' due to its specialized herbivorous diet. This diminutive species, typically measuring 16-19 cm (6.3-7.5 inches) in length and weighing 40-70 grams (1.4-2.5 oz), is the smallest of the seedsnipes, and indeed, one of the smallest shorebirds globally. Its distinctive field marks include a stocky, plover-like body with short legs, a smal...
Found in arid and semi-arid grasslands, steppes, scrubland, and open country, from sea level up to high Andean plateaus exceeding 4,000 meters.
Primarily herbivorous, consuming a variety of seeds, leaves, and buds from small plants, supplemented occasionally by small invertebrates such as insects or spiders.

The Least Seedsnipe boasts a broad distribution across southern South America, extending from Ecuador, Peru, Bolivia, and Chile south through Argentina to Tierra del Fuego and the Falkland Islands. Its breeding range encompasses much of the Patagonian steppe in Argentina and Chile, as well as hig...
