The brown-eared bulbul (Hypsipetes amaurotis) is a medium-sized songbird native to East Asia and characterized by its prominent reddish-brown ear-coverts. Previous studies on it have primarily been from the taxonomic and morphological aspects, with limited research in the realm of molecular biology. In this study, we sequenced and annotated the complete mitochondrial genome of H. amaurotis, which was the first reported complete mitogenome of the genus Hypsipetes. The mitogenome of H. amaurotis is 17,871 bp in length and was predicted to encode 37 typical mitochondrial genes, including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs). Specifically, this mitogenome contains two D-loop control regions that are of similar length and sequencing pattern. A total of 8 Pycnonotidae and six outgroup taxa were used to determine the phylogenetic placement with two methods: Maximum Likelihood Approximation (IQ-TREE) and Bayesian inference (MrBayes). Our findings reveal that H. amaurotis is phylogenetically closely related to Ixos mcclellandii. The outcomes are generally consistent with the phylogenetic trees constructed in previous studies. The data gathered from this research provides valuable insights for future genomic investigations into the evolution, ecology, and conservation of this species.
