The Bahamas Bananaquit or Bahamanian Bananaquit (Coereba bahamensis), by some authorities (Coereba flaveola bahamensis), is a species of passerine bird tentatively placed in the Thraupidae family and is a member of the Bananaquit complex, but classified as incertae sedis by the AOU. The precise classification of bananaquits is debated, and they are often placed their own family Coerebidae. It feeds predominately on nectar. Historically the bird was a single species but has since been split.[1]
Taxonomy
Coereba bahamensis was split from the mainland species C. flaveola following phylogenetic evidence that they are genetically distinct enough to be considered separate species.[2]
The following excerpt is from a study published in 2008, from BMC Evolutionary Biology:
Phylogenetic support for taxonomic distinctions among subspecies Our molecular systematic appraisal of bananaquits permits us to assess phylogenetic support for taxonomic distinctions among the many named subspecies. Two subspecies groups were recognized by Paynter [7]: bahamensis (from the Bahamas) and flaveola (representing all other populations), but most populations in the West Indies have received specific or subspecific epithets at some time in the past, Bond [29] recognizing 16 subspecies. Our data confirm the genetic distinctiveness of the bahamensis birds; however, the flaveola group encompasses mtDNA haplotype clades that are nearly as divergent as flaveola and bahamensis groups. For example the JA/CY/DR clade is approximately 5% diverged in mitochondrial sequence from the remainder of the populations recognized as the flaveola subspecies by Paynter [7]. Additionally, subspecies such as portoricensis on Puerto Rico represent distinct evolutionary lineages. However, more often than not closely related or identical mtDNA haplotypes encompass several subspecies. For instance, the northern LA mtDNA haplotype clade includes four subspecies (sancti-thomae, bartholemica, martinicana, and dominicana), the two Panama bananaquits comprise different subspecies (columbiana and aterrina), and birds from Bolivia and Peru belong to three different subspecies (intermedia, dispar and alleni). Although finer genetic distinctions consistent with morphological differences between populations may exist, this study adds evidence that presently recognized bird subspecies often do not represent historically and phylogenetically equivalent evolutionary lineages (e.g., [30]).[3]
