The Rodrigues solitaire (scientific name Pezophaps solitaria) was a large, flightless bird belonging to the family Columbidae (pigeons and doves). It was endemic to Rodrigues, a remote island in the Mascarene archipelago of the southwestern Indian Ocean. The species is extinct; the last reliable accounts date to the late 18th century.

The Rodrigues solitaire was a close relative of the dodo (Raphus cucullatus), another extinct flightless pigeon from the neighboring island of Mauritius. Molecular and morphological analyses place both species within a distinct clade of island-dwelling columbids.
Physical description
The bird measured approximately 70–80 cm (28–31 in) in length and weighed around 10–15 kg (22–33 lb). It possessed a robust, heavily built body, short wings reduced to vestigial stubs, and strong, stout legs adapted for terrestrial locomotion. The plumage was reported by early observers to be primarily brownish‑gray with a slightly iridescent sheen, and the head featured a small, hooked beak. The male was thought to have a more pronounced crest of feathers than the female, though sexual dimorphism is not well documented.
Distribution and habitat
P. solitaria inhabited the dense native forest and scrubland of Rodrigues Island. It was a ground‑dwelling forager, feeding on fruits, seeds, and possibly small invertebrates. The bird’s restricted range made it vulnerable to habitat alteration.
Historical accounts
The first European description of the Rodrigues solitaire appears in the travel narratives of French explorer François Leguat (late 17th century) and Dutch naturalist Peter C. K. van Aken (early 18th century). These accounts noted the bird’s inability to fly, its large size, and its tendency to be hunted for meat. In 1841, British zoologist Richard Owen examined skeletal remains that had been collected from the island, providing the first scientific description of the species.
Extinction
The Rodrigues solitaire became extinct by the end of the 18th century. Contributing factors included:
- Overhunting: The bird was hunted for its meat by early settlers and passing ships.
- Introduced predators: Cats, rats, and pigs introduced by humans preyed upon eggs, chicks, and juveniles.
- Habitat destruction: Deforestation for agriculture reduced available nesting and foraging sites.
The exact date of the last sighting is uncertain; the most reliable account dates to 1761, when a French naturalist reported observing a solitary individual.
Specimens and scientific study
Only a limited number of subfossil bones and a few fragmentary specimens survive in museum collections (e.g., the Natural History Museum, London; Muséum national d'Histoire naturelle, Paris). These remain the primary sources for modern morphological and phylogenetic analyses.
Significance
The Rodrigues solitaire, together with the dodo, exemplifies the vulnerability of island endemics to human activities and introduced species. It continues to be a subject of interest in evolutionary biology, biogeography, and conservation education as an illustration of rapid anthropogenic extinction.
