The taxonomical relations of F. panarium remain unclear. It is sometimes placed in a distinct family Foratidae. It was considered possibly related to cuckoos, turacos and/or the puzzling hoatzin of the Amazon.[1] A phylogenetic analysis conducted by Field & Hsiang (2018) indicated that Foro panarium was a stem-turaco.[2]
