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. 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".
All Crypturellus are in the family Tinamidae, thus are classed as ratites, making them relatives of the cassowary, emu, kiwi, ostrich and rhea. Unlike these larger birds, however, tinamous still have the ability to fly, albeit somewhat weakly and not for prolonged periods (typically flying up, to perch on branches, when fleeing threats). It is thought that all ratites evolved from prehistoric flying birds, hence their distant populations in Australia and Oceania; the tinamou is the closest, smallest living relative of these birds.

Rare
Under 5% of wildlife watchers report an Undulated Tinamou sighting in Campo Grande on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 221 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
October and December
In those months about 10% of wildlife watchers report an Undulated Tinamou in Campo Grande on a given day, against under 5% in January–September and November, the lowest months. Those are among Campo Grande's wettest months, with about 150 mm of rain a month against 30 mm in July.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Undulated Tinamou sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Campo Grande, in our data
Campo Grande is the only city on Wallace's Line with enough records to rate Undulated Tinamou sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Undulated Tinamou is recorded against all the birds logged in Campo Grande (24 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
