Cinereous Tyrant vs Hudson's Black-Tyrant

The Cinereous Tyrant and Hudson's Black-Tyrant are both small, dark flycatchers of the genus Knipolegus. The Cinereous Tyrant is more likely to be seen alone or in pairs, while Hudson's Black-Tyrant is less conspicuous and migratory. Key differences include plumage details and habitat preferences.

Look for the gray wingbars and gray outer tail feather webs in male Cinereous Tyrants. Females have rufous on the crown and two white wingbars. Hudson's Black-Tyrant lacks these specific markings and is more migratory, often found in different habitats depending on the season.

Both species are similar in size, typical of small tyrant flycatchers.

Male Cinereous Tyrants are black with red irides, gray wingbars, and gray outer tail feather webs. Females are olive-brown with rufous on the crown and nape, white lores, and two white wingbars. Hudson's Black-Tyrant males are also black but lack the distinctive gray wingbars and tail feather markings.

Cinereous Tyrants are often seen actively twitching their tails and gleaning insects, typically alone or in pairs. Hudson's Black-Tyrant is less conspicuous and tends to be more migratory.

Cinereous Tyrants are found in northern Argentina, Bolivia, Paraguay, and southwestern Brazil below 1000 meters. Hudson's Black-Tyrant breeds in the Monte and Espinal habitats of Argentina and migrates north to Bolivia and western Paraguay.
