The first complete mitochondrial genome sequence of an Australian raven (Corvus coronoides)

Here, we report the complete mitochondrial genome of an Australian raven (Corvus coronoides). The mitogenome of C. coronoides was characterised as a circular molecule of 16,925 bp in length encoding a typically conserved structure similar to those of other Corvidae. It consisted of 13 protein-coding genes (PCGs), two rRNA genes, and 22 tRNA genes, with all protein-coding sequences commencing with methionine. The lengths of 12S ribosomal RNA and 16S ribosomal RNA were 980 bp and 1600 bp, respectively, and were located between tRNA-Phe and tRNA-Leu. The overall base composition of the mitogenome of C. coronoides was slightly higher AT (56.0%) content than GC (44.0%). A phylogenetic tree using available complete mitogenome sequences of the family Corvidae revealed a close evolutionary relationship of C. coronoides with the now extinct Chatham raven (C. moriorum), a large songbird that was native to the Chatham Islands east of New Zealand.
