Psaltria exilis The pygmy bushtit (Aegithalos exilis) is a species of bird in the bushtit family Aegithalidae.
[2] The species was once placed, along with the rest of its family, with the true tits, Paridae.
[3] It is endemic to Indonesia, where it occurs only on the island of Java.
The pygmy bushtit was formerly placed in its own monotypic genus Psaltria.
It was moved to the current genus Aegithalos based on the results of a molecular phylogenetic study published in 2016.
