Spotted Nothura

Identification

The spotted nothura is a small tinamou measuring approximately 24 to 25.5 cm in length. Its plumage is characterized by brown upper parts with streaked buff markings, while the under parts are buff with streaking and barring in black and brown, particularly on the breast and flanks. The crown is black streaked with buff, and the throat is distinctly white. The legs are dull yellowish-grey or brown. A notable feature shared only with the closely related Chaco nothura is barring on both webs of the primary feathers, a distinguishing characteristic among tinamous.

Coloration varies considerably across the species' range, influenced by regional soil differences and environmental conditions. This variation follows recognized patterns across its nine recognized subspecies, which range from northeastern Brazil south to Argentina.

Range & Habitat

The spotted nothura is native to eastern and southern Brazil, Paraguay, Bolivia, Uruguay, and eastern and northern Argentina. The species avoids the Mata Atlântica forests and coastal planalto uplands. It inhabits dry savanna grasslands, temperate grasslands, and pasture land, occurring at elevations up to 2,300 m.

Behaviour & Diet

This species produces a characteristic call consisting of a series of brief high-pitched notes. The spotted nothura feeds on both plant and animal matter, with a diet primarily comprising seeds and insects. Notably, populations in Argentina appear to consume significantly more animal matter than those in other regions of the range.

The species exhibits remarkable reproductive capacity, enabling rapid population recovery. Females reach maturity within two months and can produce five to six broods annually. Males, conversely, mature more slowly but take full responsibility for incubation and chick-rearing. Each clutch contains 4 to 6 eggs, which have distinctive glossy, porcelain-like shells colored rich maroon or chocolate brown—a characteristic feature of tinamous.

Best Time & Places to See It

The spotted nothura is widely distributed across grassland habitats throughout much of southern and central South America, with an occurrence range of 3,900,000 km². Its adaptability to pasture lands and grassland habitats makes it potentially accessible across its broad range, from Brazilian grasslands through Paraguay and into Argentina. The species' high reproductive rate and wide distribution have resulted in its IUCN classification as Least Concern, despite hunting pressure.

Photography Tips

Photographing the spotted nothura presents challenges typical of ground-dwelling grassland birds. Early morning hours often provide the best light for capturing this species in its natural habitat. The bird's cryptic coloration and preference for remaining on the ground mean patience and careful approach are essential. Pay attention to subtle plumage details—the white throat, streaked crown, and distinctive barring on the flanks—which help distinguish this species from other tinamous. The species' rapid reproduction and relatively stable populations mean encounters may be more frequent than with other tinamou species in suitable grassland habitats.
