Tichodroma

For the journal, see Tichodroma (journal).

Tichodroma is the only known genus in the family Tichodromidae. Initially, Linnaeus placed Tichodroma in the family Certhiidae, along with the treecreepers,^[1] while other authorities have placed it the nuthatch family Sittidae, as its own subfamily. A 2016 phylogenetic study of members in the superfamily Certhioidea suggests it is a sister of the Sittidae.^[2]

Certhioidea Tichodromidae: wallcreeper – 1 species Sittidae: nuthatches – 29 species Salpornithidae: spotted creepers – 2 species Certhiidae: treecreepers – 9 species Polioptilidae: gnatcatchers – 22 species Troglodytidae: wrens – 96 species
