Further genetic and bioacoustic investigation is required to resolve the taxonomic status of this lineage. This cryptic lineage may be more widespread in its breeding quarters, extending to the Chinese and Russian mainland, in which case the name florensis would apply to it. Conclusions: Our data show that the mitochondrial signature previously documented in resident Taiwanese populations of the Northern Boobook extends to migratory populations. Further, the samples belong to the mitochondrially distinct lineage previously characterized in resident Taiwanese populations rather than to the well-known nominate migratory lineage. This is the first official record of this species in Singapore and represents a considerable range extension for the species. Results: Two out of four Singaporean samples and the Brunei sample were identified as Northern Boobooks. Methods: PCR of cytochrome-b and Sanger sequencing of Ninox samples from Singapore and Brunei were used to determine sample identity. Overlap in ranges during migration and morphological similarity have led to difficulties in distinguishing the Brown Boobook from the Northern Boobook. For the purposes of clarity and brevity, we will refer to this mitochondrial lineage as the "undetermined lineage" henceforth.īackground: The Brown Hawk Owl complex is said to consist of three species, the Brown Boobook (Ninox scutulata), the Chocolate Boobook (Ninox randi) and the Northern Boobook (Ninox japonica), which includes the nominate migratory lineage Ninox japonica japonica and a mitochondrially distinct lineage of taxonomically uncertain status that has been recorded year-round at least in Taiwan. 2015), a name based on type material from the wintering range in East Indonesia that may extend to Taiwan if future research can verify the connection between the type of florensis and mainland Chinese breeding populations. (2013) refer to this as an unnamed population, but it may well have a taxonomic name already if mainland populations are shown to belong with it: based on morphological considerations, many treatises nowadays refer to mainland populations as N. Avian Research *Correspondence: 1 Department of Biological Sciences, National University of Singapore, 14 Science Drive 4, 117543 Singapore, Singapore Full list of author information is available at the end of the article of Taiwan only, unsampled breeding populations in mainland China and Russia may well be closely related or identical to this lineage. This is further supported by the relatively high abundance of terrestrial prey remains preserved in sediment deposits at former laughing owl nest sites. Osteological analyses and a comparison of the wing and leg proportions of the laughing owl with those of other owls supports Gould's (1865) contention that it was largely a terrestrial owl, and predominantly caught prey on the ground. Accordingly, we synonymize Sceloglaux with Ninox, and recommend that the laughing owl hereafter be referred to as Ninox albifacies. Our results provide strong support for Sceloglaux being nested within Ninox Hodgson, 1837, as sister taxon to the clade containing the barking owl (Ninox connivens Latham, 1801), Sumba boobook (Ninox rudolfi Meyer, 1882), and morepork (Ninox novaeseelandiae Gmelin, 1788). ![]() Here, we present a high-coverage mitogenome for the sole member of the genus, New Zealand's extinct laughing owl (Sceloglaux albifacies Gray, 1845), and assess its phylogenetic relationships. It does not store any personal data.The taxonomic affinities of the monotypic owl genus Sceloglaux Kaup, 1848 have been widely debated.
