Figure 1. A in Small islands and large biogeographic barriers have driven contrasting speciation patterns in Indo-Pacific sunbirds (Aves: Nectariniidae)

Figure 1. A, map of the Indo-Pacific region with study regions marked inside boxes. The range of the olive-backed sunbird is shaded horizontally in yellow, the range of the black sunbird vertically in purple, both according to BirdLife International. Seas deeper than 200 m are represented by a darker blue. Biogeographic barriers (Wallace, 1863; Lydekker, 1896) are represented with red lines. B, map of south-east Sulawesi and the Wakatobi Islands in Wallacea, with olive-backed sunbird sampling sites marked with yellow downward-pointing triangles, black sunbird sampling sites with purple upward-pointing triangles. C, map of Australia and New Guinea on the Sahul Shelf, with olive-backed sunbird sampling sites marked with yellow downward-pointing triangles, black sunbird sampling sites with purple upward-pointing triangles. D, map of the Bismarck Archipelago with the sampling site of the B10K black sunbird marked with a purple triangle.Published as part of Marcaigh, Fionn Ó, Kelly, David J., O'Connell, Darren P., Analuddin, Kangkuso, Karya, Adi, Mccloughan, Jennifer, Tolan, Ellen, Lawless, Naomi, Marples, Nicola M., O, Darren P. & Connell, 2022, Small islands and large biogeographic barriers have driven contrasting speciation patterns in Indo-Pacific sunbirds (Aves: Nectariniidae), pp. 1-21 in Zoological Journal of the Linnean Society CLXVI (CLXVI) on page 2, DOI: 10.1093/zoolinnean/zlac081, http://zenodo.org/record/757383
