Taxonomy
The yellow-billed tit-tyrant's genus, Anairetes, is believed to be most closely related to the genera Mecocerculus and Serpophaga; however, there is no definitive evidence supporting this claim. Members of the genus Anairetes are known commonly as tit-tyrants because their active foraging behavior and crests are reminiscent of the true tits in the family Paridae.
