Les oiseaux de l'archipel des loyauté (nouvelle-calédonie) : Inventaire et éléments d'écologie et de biogéographie

摘要: The avifauna of the Loyalty Islands comprises 62 species, including 14 breeding or erratic seabirds, 5 migratory birds, 7 herons, ducks and rails, 4 birds prey, 28 indigenous land breeders (belonging to 33 subspecies) 2 species introduced from Grande Terre (main island New Caledonia). Six are endemic: 3 on in (New Caledonian Friarbird Philemon diemenensis, Green-backed White-eye Zosterops xanthochrous, Striated Starling Aplonis striatus) only found (Ouvea Parakeet Eunymphicus uvaeensis, Large Lifou inornatus Small Z. minutus). is an endemic genus New Caledonia. Eight subspecies both the 11 exclusive Islands. Of 24 taxa whose geographical origin could be identified, 58% identical or similar those Terre, 105 km away, 42% have affinities with Vanuatu, twice as far away (225 km). paths cyclones explain specific influence Vanuatu. correlation between islands’land area number species that successfully settled very close (r = 0.97) confirms this biogeographical standard. frequencies vary, rare localized limited some islands (Bluefaced Parrotfinch Erythrura trichroa, Ouvea Parakeet), possibly extinct (Island Thrush Turdus poliocephalus) others frequency varies widely place (Fan-tailed Cuckoo Cacomantis flabelliformis, Gerygone flavolateralis, Silvereye lateralis), while show high (Red-bellied Fruit-Dove Ptilinopus greyii), average (Melanesian Flycatcher Myiagra caledonica, Sacred Kingfischer Todiramphus sanctus) low (Emerald Dove Chalcophaps indica) that remain comparable these islands. ecology has been determined associated wide forests, e.g. Parakeet, typical open settings. The threats onto mainly linked habitat destruction impact species. A effort should made ensure protection populations for which there greatest concern, i.e.
