• Phylogenetic placement: Passeri: Passerides: Sylviida: Aegithaloidea
• Distribution: Eurasia and western North America
• Number of extant genera: 3
• Number of extant species: 11

Traditional genus-level classification of extant Aegithalidae following the AviList checklist v2025.(link) The number of subspecies is given in parentheses. The phylogenetic arrangement is based on Päckert et al. (2010). The BOW Phylogeny Explorer tree v1.6 differs by considering Psaltriparus being embedded in Aegithalos. (link)
