# Complete mitochondrial genome sequencing and phylogenetic analysis of the Light-vented Bulbul (Pycnonotus sinensis) killed by window collision in South Korea in 2023

## TL;DR

This paper reports the full mitochondrial genomes of five Light-vented Bulbuls found dead in South Korea and shows they are closely related to a Chinese subspecies.

## Contribution

The study provides complete mitochondrial genome sequences and phylogenetic analysis of Pycnonotus sinensis in South Korea.

## Key findings

- The mitochondrial genomes of five P. sinensis individuals are 16,923bp long with standard gene content.
- South Korean P. sinensis forms a monophyletic group with P. sinensis hainanus from China.
- The findings suggest high genetic similarity and regional adaptation insights.

## Abstract

The Light-vented Bulbul (Pycnonotus sinensis) has rapidly expanded across East Asia, particularly in South Korea since the early 2000s. This study presents the complete mitochondrial genomes of five individuals died from window collisions in Seoul. The genomes, sequenced using next-generation sequencing technology, are 16,923bp long and contain 13 protein-coding genes, 22 tRNAs, and 2 rRNAs. Phylogenetic analysis revealed that South Korean P. sinensis forms a monophyletic clade with P. sinensis hainanus from China, indicating high genetic similarity. These findings provide essential data for understanding of P. sinensis population structure and regional adaptation.
