Fauna of Pacific Islands
JOrnitho: I'm making this new topic to discuss the animals living in the Pacific islands. Since there is so many islands in the world, I believe that discussing about them in only one topic would be confusing. So, for the sake of organization, I'll leave the other topic that I did to discuss only the fauna of Atlantic islands. To start this topic, I want to talk about the Easter Island. I believe that it would have an interesting fauna, with a combination of species introduced by the humans here and those from the close Eonesia. For example, the Chilean tinamou (Nothoprocta perdicaria) that was introduced here could have a flightless descendant in the Neocene of the island.

JOrnitho: Would a hummingbird be capable of reaching the island? Or another bird could have evolved to feed on nectar and thus help with pollination?
Автор: JOrnitho пишет: Would a hummingbird be capable of reaching the island? Their flight abilities make it possible. So, it's not a main question here. JOrnitho пишет: to feed on nectar and thus help with pollination Here is the question. The flora of islands is usually rather poor. So, Stephen Buchmann and Gary Paul Nabhan in their book "The Forgotten Pollinators" noted the poor flora and pollinator diversity of the Galapagos Islands compared to the continent. Of course, Hawaii seem to ba an exception, but I think the fauna of pollinator birds at the remote islands of non-continental origin must be poor.
JOrnitho: Автор пишет: but I think the fauna of pollinator birds at the remote islands of non-continental origin must be poor. I see. Then I think that it would be more probably that insects are the ones doing pollination here.
