The length was about 26 cm. The head, the throat, and the breast mantle were beige. The chestnut upperparts with a pale purple sheen on the carpals and the small wing coverts contrasted with a chocolate-coloured belly.
The Thick-billed Ground Dove might have preferred dry beach forests on the Solomon Islands
of Makira
(formerly San Cristobal), and the tiny island of Ramos which belongs to Malaita
. It is likely that it also occurred on other islands in that region in the past. It was a ground-dweller like its congeners, and so it was an easy prey for introduced rats and feral pigs, cats and dogs. The logging of the lowland forests in its habitat and the hunting sealed its fate.
Despite the fact that it was last seen in 1927, the IUCN has long hesitated to declare this species extinct. Many surveys in its former range were undertaken in the later part of the 20th century (Dutson, 2003), but when the last search for this species on Ramos in 2004 had failed too it was officially declared extinct in 2005. It probably became extinct in the mid-20th century following the increased activity around the time of World War II
, which affected several populations of endemic birds in the region.
