# The genome sequence of the black-headed gull, Chroicocephalus ridibundus (Linnaeus, 1766)

## TL;DR

This paper provides the genome sequence of the black-headed gull, including chromosomal and mitochondrial data.

## Contribution

The novel contribution is the first genome assembly for the black-headed gull, including chromosomal pseudomolecules and mitochondrial DNA.

## Key findings

- The genome assembly spans 1,417.60 megabases and includes 33 chromosomal pseudomolecules.
- The mitochondrial genome is 16.82 kilobases in length and has been fully assembled.

## Abstract

We present a genome assembly from an individual male
Chroicocephalus ridibundus (the black-headed gull; Chordata; Aves; Charadriiformes; Laridae). The genome sequence spans 1,417.60 megabases. Most of the assembly is scaffolded into 33 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 16.82 kilobases in length.
