Viudita Patagona vs Viudita Picoplata

Hudson's Black-Tyrant and Spectacled Tyrant can be distinguished by their flight displays and wing patterns. The Spectacled Tyrant male is notable for its striking white wings visible in flight, while Hudson's Black-Tyrant is more uniformly dark and less conspicuous. Both species are migratory, but they occupy different habitats during breeding and non-breeding seasons.

Look for the white wings of the male Spectacled Tyrant during flight. Observe behavior: Spectacled Tyrants perform aerial displays with wing snaps. Note habitat: Hudson's Black-Tyrant prefers shrubby habitats.

The Spectacled Tyrant male has a dramatic contrast with largely white wings visible during flight, whereas Hudson's Black-Tyrant is more uniformly dark. Female Spectacled Tyrants are brownish with rusty wings and streaking, which can cause confusion.

Spectacled Tyrant males perform a noticeable aerial display with a wing snap that creates a finger-snapping sound. Hudson's Black-Tyrant is less conspicuous and does not have such a display.

Hudson's Black-Tyrant breeds in the Monte and Espinal habitats of Argentina and migrates to Bolivia and Paraguay. Spectacled Tyrants are migratory across the Andes, wintering on the Argentine or Bolivian side.
