Yellow-green Vireo vs Black-whiskered Vireo

In short

The Yellow-green Vireo and Black-whiskered Vireo are similar in size and general appearance, but the Black-whiskered Vireo is distinguished by its black lateral throat stripe and browner back. Both species have greenish plumage, but the Yellow-green Vireo lacks the distinctive 'whiskers' of the Black-whiskered Vireo.

Identification tips

• Look for the black lateral throat stripe on the Black-whiskered Vireo.
• Note the browner back of the Black-whiskered Vireo compared to the more uniformly green Yellow-green Vireo.
