Hi !
Caloenas canacorum is from New Caledonia.
Caloenas canacorum was larger than C. nicobarica, the bird must have been about 43 cm from head to tail. That's all I know.
Bye Alex

Elsewhere in Tonga, bird bones have been recovered from archeological sites on Tongatapu (unstudied; ref. 28), Niuatoputapu (only seabirds; ref. 29; unpublished observations), and Lifuka. From the Tongoleleka Site on Lifuka (Ha'apai Group), cultural strata that span much of Tonga's prehistory (ca. 3000-1000 years B.P.; refs. 30 and 31) produced bones of the megapodes Megapodius cf. molistructor and M. alimentum, the pigeons Caloenas cf. canacorum, Ducula cf. david, Ducula new sp., and D. pacifica, and starling Aplonis tabuensis (32). Only the last two species survive anywhere today. All except M. cf. molistructor and C. cf. canacorum have been recovered at 'Anatl. These two extinct species are otherwise known only from New Caledonia (33). www.pnas.org/cgi/reprint/90/3/818.pdf |

New Caledonia has two extinct columbids, both the largest in their respective genera, Gallicolumba longitarsus and Caloenas canacorum, the latter almost 25% larger than C. nicobarica (Balouet & Olson 1989). www.rsnz.org/publish/jrsnz/2001/40.pdf |

Well, that's far back in time! Do we have any ancient representations of the bird, telling us what it was like?

@ Bowhead Whale
No, not yet, as far as I know nobody of us did see any bones of this species.

From subfossil bones found on New Caledonia and Tonga, an extinct species, the Greater Maned Pigeon (Caloenas canacorum) was described. It was a sizeable bird, about one-quarter larger than the Nicobar Pigeon. Considering that it must have been a good source of food, it was most likely hunted to extinction by the first human settlers of the islands where it occurred.
It remains a mystery to me why New-Zealand has just one pigeon while at the same time much smaller islands have five or more. The species richness, taxonomic diversity, and geographic distribution of pigeons and doves (Columbidae) have been altered irreversibly in Polynesia by 3500 years of human activity. Natural (without human influence) columbid faunas are estimated primarily by studying prehistoric bones. In all Polynesian island groups studied (except outlying Easter Island, Hawaiian Islands, or New Zealand), the prehistoric columbid faunas had more species, more genera, and more species per genus than modern faunas from the same island. Congeneric species pairs or triplets occurred on many islands for Ducula, Ptilinopus, and Gallicolumba. The losses of Polynesian columbids include the extinction of at least 9 species in the genera Ducula, Ptilinopus, Macropygia, Caloenas, Gallicolumba, and Didunculus as well as the extirpation of numerous island populations of extant species. If not for human impact, a typical East Polynesian island would support at least 5–6 species of columbids in 3–4 genera (compared to 0–3 species in 0–3 genera today). A typical West Polynesian island would support at least 6–7 species in 4–5 genera (compared to 1–6 species in 1–5 genera today). Since all Polynesian pigeons and doves are frugivorous and/or granivorous, their decline in recent millennia probably has affected the composition of Polynesian forests by limiting inter- and intra-island dispersal of plant propagules. |
