Species assemblages on islands are products of colonization and extinction events, with traditional models of island biogeography emphasizing build-up of biodiversity on small islands via colonizations from continents or other large landmasses. However, recent phylogenetic studies suggest that islands can also act as sources of biodiversity, but few such “upstream” colonizations have been directly observed. I report four putative examples of recent range expansions among the avifauna of Makira and its satellite islands in the Solomon Islands, a region that has recently been subject to extensive anthropogenic habitat disturbance. They include three separate examples of interisland dispersal, involving
