The rufous-headed ground roller (Atelornis crossleyi) is a species of bird in the ground roller family, Brachypteraciidae. It is endemic to Madagascar.

Unlike the four other species, the fifth species lives in the dry southwestern spiny bushes of Madagascar. The Atelornis crossleyi species of the ground rollers lives with most of its family in humid forests. The International Union for Conservation of Nature considers the bird to be near-threatened because, although it is present in a number of protected areas, it is hunted for food and the forests in which it lives are threatened by slash-and-burn cultivation. The bird's scientific name commemorates Alfred Crossley who collected mammals, birds, butterflies and moths in Madagascar and Cameroon in the 1860s and 1870s. Many of these are in the Natural History Museum, London.
The sexes are similar in this distinctively-coloured bird about 25 cm (10 in) long. The head and breast are reddish-brown, the upper parts olive green and the underparts buff with darker markings. There is a narrow... Wikipedia →

Rare
Under 5% of wildlife watchers report a Rufous-headed Ground Roller sighting in Mantadia National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 83rd most-seen of the 98 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rufous-headed Ground Roller in Mantadia National Park on a given day, so our monthly data shows no clear season. January to April have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Rufous-headed Ground Roller sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
2nd of 2
Of the 2 parks where we can rate Rufous-headed Ground Roller sightings, Mantadia National Park ranks 2nd at under 5%. The best odds are in Ranomafana National Park (Madagascar, about 30%).
GBIF citizen-science records
It is estimated from how often the Rufous-headed Ground Roller is recorded against all the birds logged in Mantadia National Park (14 verified sightings from 2019 to 2026), 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.
