Mitogenome assembly
The mitochondrial genome was assembled from the primary genome assembly using MitoHiFi v3 (Uliano-Silva et al., 2022). MitoHiFi identified the rock warbler Origma solitaria (NCBI reference sequence NC_053100.1; Feng et al., 2020) as the most closely-related publicly available mitochondrial genome. The mitochondrial genome was visualised with MitoZ v2.3 (Meng et al., 2019).
