Taxonomy and systematics
Cabanis's wren, with what are now the canebrake wren (C. zeledoni) and the isthmian wren (C. elutus), were called the plain wren. The three were split from each other in 2016 on the basis of a 2015 publication that described their different vocalizations and genetic divergence.[1][2] Cabanis's wren is monotypic according to the International Ornithological Committee (IOC) and the Clements taxonomy.[1][3] However, BirdLife International (BLI) retains C. modestus as "plain wren" with elutus as a subspecies of it rather than as a full species.[4]
