Genetic evidence indicates that Tropical Pewee is paraphyletic (Harvey et al. 2020), and vocalizations also differ significantly between populations (Boesman 2016m). Therefore this species is split into three species: a monotypic Tumbes Pewee Contopus punensis; a polytypic Southern Tropical Pewee Contopus cinereus, with subspecies pallescens and cinereus; and a polytypic Northern Tropical Pewee Contopus bogotensis, with subspecies brachytarsus, rhizophorus, aithalodes, bogotensis, and surinamensis. Note that the split does not align with the three previously recognized groups: we had included subspecies bogotensis and surinamensis together with pallescens and cinereus in the group Tropical Pewee (Tropical) Contopus cinereus [cinereus Group], but bogotensis and surinamensis instead are allied to the taxa in the group Tropical Pewee (Short-legged) Contopus cinereus [brachytarsus Group].
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
