Application to the work of E. Bellemain and co-authors: linking geographical distribution and phylogenetic data for bananaquit birds Bellemain and co-authors performed a phylogenetic analysis of bananaquit birds (Coereba flaveola) caught in various places in Latin America and Caribbean islands. 20 Geographical positions of catching sites are displayed (in their Fig. 1 ) and the genetic analyses led to two phylogenetic trees (their Figs. 2 and 3) . Relationships between geographical origin of birds and taxonomy are discussed, and conclusions about the evolutionary history are made. Despite that this work has been successfully achieved without the help of any visualisation tool, a coloring based on the taxonomic tree would have considerably helped these authors.
