ネズミタイランチョウ Knipolegus signatus

Rare flycatcher found in cloud forest along the east slope of the Andes in northern and central Peru, barely reaching over the border into southeastern Ecuador. Male is dark sooty gray; female is grayish-olive with pale wingbars and faint streaking below. Similar to White-winged Black-Tyrant, but male Jelski’s is grayer and lacks white in the wings (which is usually only evident in flight) and female Jelski’s is much darker, especially on the underparts. No overlap with Plumbeous Black-Tyrant.
