Hábitat

Es un ave común dentro de su área de distribución, habita en bosques, matorrales y áreas de crecimiento secundario (donde rebrotan los árboles tras la tala).

Vive sobre el suelo, por entre la vegetación baja. Tiene reclamo silbante.

Alimentación

La dieta consiste en semillas, bayas e insectos.

Reproducción

Según algunos estudios el macho se aparea con varias hembras, que se desplazan en grupo de un macho a otro. Cada macho guarda un solo nido, en el cual incuba los huevos de todas sus parejas.

Subespecies

Se conocen seis subespecies de Crypturellus undulatus:​

  • Crypturellus undulatus manapiare – sudeste de Venezuela.
  • Crypturellus undulatus simplex – Guyana .
  • Crypturellus undulatus adspersus – norte de Brasil.
  • Crypturellus undulatus yapura – desde Ecuador hasta el oeste de Brasil.
  • Crypturellus undulatus vermiculatus – este de Brasil.
  • Crypturellus undulatus undulatus desde el este de Bolivia hasta Paraguay y Argentina.

Undulated tinamou

The undulated tinamou (Crypturellus undulatus) is a species of ground bird found in a wide range of wooded habitats in eastern and northern South America.

Undulated Tinamou is a ubiquitous species of river forest and second growth in the Amazon basin but also occurs in the drier tropical and subtropical regions of south central and eastern South America. As with most species in the genus Crypturellus, its plumage lacks strong color patterns. A ground-foraging omnivore, Undulated Tinamou feeds on small fruits, seeds, and insects and is considered fairly common throughout its range. Its distinctive three-note song often is among the first bird sounds one learns in Amazonia.

Etymology

Its generic name Crypturellus is formed from three Latin or Greek words – kruptos meaning «covered» or «hidden», oura meaning «tail», and ellus meaning «diminutive». Therefore, Crypturellus means small, hidden tail. The specific name undulatus originates from the Latin word unda, meaning «wave», and means «furnished with wave-like markings».

Taxonomy

All tinamous are from the family Tinamidae, so are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds.

Subspecies

  • C. u. manapiare is only known with certainty from the vicinity of the Ventuari River in northern Amazonas State in Venezuela, but probably also occurs in southwestern Amazonas State.[3][8]
  • C. u. simplex occurs in southern Guyana, French Guiana (where only known from sight records), and northeastern Brazil (east of the Rio Negro and north of the Amazon River).
  • C. u. adspersus occurs in Brazil south of the Amazon River, from the Tapajós River to the Madeira River.
  • C. u. yapura occurs in southeastern Colombia, eastern Ecuador, northeastern and east-central Peru, and western Brazil (east to Rio Negro and the Purús River).
  • C. u. vermiculatus occurs in eastern Brazil from Maranhão, Tocantins, and Mato Grosso and east.
  • C. u. undulatus occurs in southeastern Peru, eastern and northern Bolivia, the Pantanal region in Brazil, Paraguay, and northern Argentina.

Habitat

Tropical zone, mainly in forest, dry scrub, cerrado, savanna, islands of forest in savannas, forest edgevideo , chaco forest, várzea, open dry forest, moist gallery forest, river-island forest; also in young secondary forest and near flooded areas. In chaco forest and caatinga of Brazil found only at edge, possibly because replaced here by species better adapted to dry conditions.

Movement

Presumably sedentary in general. Moves away from river islands during flooding, e.g. observed to cross R Japurá from várzea to terra firme during the annual flood (apparently few documented records of this kind of behaviour). Has been seen flying over small channels and lagoons on Amazon.

Diet and Foraging

Small fruits, seeds and insects, especially bugs (Hemiptera), Odonata, and adult and larval beetles (Coleoptera).

Sounds and Vocal Behavior

Distinctive 3-note melancholy “whoo, whu-whooo”video , sometimes rising at end, repeated at rather long intervals.

Breeding

Feb–May in Colombia. Clutch 4–5 eggs  , pale pink  , wine-pink or pale ash; incubation 17 days (in captivity).

Conservation Status

Conservation status on BirdlifeLC Least Concern

Not globally threatened (Least Concern). Generally common in floodplain, várzea and gallery forest throughout Amazonia, where its easily-identifiable song is a charateristic sound. Declining in cerrado region of C Brazil as a result of extensive habitat deterioration and intense hunting pressure; adversely affected also by widespread deforestation of Amazonia. In SE Brazil survives well in two areas of NE São Paulo, where the setting-up of special reserves would have conservation benefit for this and many other species.
