Crested cuckoo-dove

The crested cuckoo-dove (Reinwardtoena crassirostris) is a species of bird in the pigeon family, Columbidae. First described by English zoologist John Gould in 1856, it is endemic to the Solomon Islands archipelago, where it mainly inhabits hill forests at elevations of 500–900 m (1,600–3,000 ft). It is a large and robust pigeon, with a length of 40–42 cm (16–17 in) and a distinctive pale purplish-grey crest. Adults are mainly bluish-grey, with a pale greyish-buff throat, blackish tail, and yellow-tipped reddish bill. Both sexes look alike. Juveniles lack the crest, have darker heads, and have duller wings.

The species feeds on fruit in the canopy and is usually seen alone or in pairs. The only known nest was found in November 1995 on an inaccessible cliff. Nests contain a single egg, which is incubated by both parents. The dove is listed as being near threatened on the IUCN Red List due to its presumed moderately small population, which is thought to be declining due to widespread deforestation in lowland forests across the species's range.
