Extant relations, such as the Bali myna ("Leucopsar rothschildi") and the white-headed starling ("Sturnia erythropygia"), have similarities in colouration and other features with the extinct Mascarene species. According to Hume, since the Rodrigues and Mauritius starlings seem morphologically closer to each other than to the hoopoe starling—which appears closer to Southeast Asian starlings—there may have been two separate migrations of starlings from Asia to the Mascarenes, with the hoopoe starling the latest arrival. Except for Madagascar, the Mascarenes were the only islands in the southwestern Indian Ocean with native starlings, probably due to their isolation, varied topography, and vegetation.
