The pin-striped tit-babbler (Mixornis gularis), also known as the yellow-breasted babbler, is a species of bird in the Old World babbler family Timaliidae that is found in South and Southeast Asia. Taxonomy and systematics The pin-striped tit-babbler was formally described in 1822 by the American naturalist Thomas Horsfield based on a specimen collected in Sumatra. He coined the binomial name Timalia gularis. The pin-striped tit-babbler was formerly placed in the genus Macronus but based on the results of a large molecular phylogenetic study published in 2019, the species was moved to the genus Mixornis that had been introduced in 1842 by the English zoologist Edward Blyth. The genus name combines the Ancient Greek mixis meaning "mixed" or "mingling" with ornis meaning "bird". The specific epithet gularis is Modern Latin meaning "-throated". The pin-striped tit-babbler belongs within a clade that includes the genera Dumetia and Timalia. The species has also been split following a study by Nigel Collar to distinguish the morphologically distinct Bornean and Javan populations, which have since been renamed the bold-striped tit-babbler (Mixornis bornensis), from the rest of the pin-striped tit-babbler species complex.
