利用DNA-DNA杂交技术，对棕树鼩 Climacteris picumnus和棕树鼩 Climacteris rufa的核DNA与雀形目其它类群的DNA进行了比较。据发现，伐木工是最古老的二分法的后代（约公元前1000年）。45-48 MYA）在Menuroidea超科中，一个还包括琴鸟，灌木鸟和园丁鸟的群体。我们认识到家庭Climacteridae，总科Menuroidea，parvorder Corvi，suborder Passeres。在Climacteridae中，我们认识到两个属，Climacteris的picumnus，rufa，melanura，erythrops和affinis，和Cormobates的leucophaea（包括minor）和placens。
The technique of DNA-DNA hybridization was used to compare the nuclear DNAs of the Brown Treecreeper Climacteris picumnus and the Rufous Treecreeper Climacteris rufa with the DNAs of other passerine taxa. The treecreepers were found to be the descendants of the oldest dichotomy (ca. 45-48 MYA) in the superfamily Menuroidea, a group that also includes the lyrebirds, scrub-birds, and bowerbirds. We recognize the family Climacteridae, superfamily Menuroidea, parvorder Corvi, suborder Passeres. Within the Climacteridae we recognize two genera, Climacteris for the species picumnus, rufa, melanura, erythrops, and affinis, and Cormobates for leucophaea (including minor) and placens.
