Bahia Wagtail-Tyrant Stigmatura bahiae

Small, slender, and long-tailed bird found in dry caatinga scrub in eastern Brazil. It has grayish brown upperparts, buffy-yellow underparts and eyebrow, and conspicuous white patches in the wings and tail. Very similar to Greater Wagtail-Tyrant, but slightly smaller and tends to have duller yellow underparts and browner upperparts. Even their voices are similar, with both species giving rollicking series of rattling trills, often as a duet. Bahia Wagtail-Tyrant’s song sounds less dry and buzzy and includes more clear, whistled notes. Recently split from Lesser Wagtail-Tyrant, which is restricted to river islands in the Amazon basin.
