The Black-whiskered Vireo: An Intriguing Bird Species

The Black-whiskered Vireo is a small, yet fascinating bird species. This songbird belongs to the Vireonidae family and resides in Central America and parts of South America during nesting season. In this blog post, we will explore the basic description of the Black-whiskered Vireo, where to find this bird, its habitat, food preferences and some cool facts about it.

Basic Description:

The Black-whiskered Vireo has a distinguishing black stripe that runs from its beak to under its eye giving it an iconic look. Additionally, it has an olive-green back with a white chest that blends into yellow-tinged undertail coverts. The bird measures approximately 13 cm in length with pointed wings and a moderately long tail.

Where To Find This Bird:

This specific type of vireo can be found in various areas throughout Central and South America during nesting season between March through September or October. Some countries you may spot them include Costa Rica, Nicaragua, Honduras as well as Colombia among others.


Black-whiskered vireos prefer lowland forests or subtropical moist forests but can also be found near pineapple plantations due to their nest building behavior using Bromeliads plants which are commonly found on these plantations.


These birds primarily feed on insects such as beetles and caterpillars along with fruits such as berries for added nutrition sources since they do not migrate like other North American species.

Cool Facts:

Did you know that the male black-whiskered vireos have larger territories than females? Also interestingly enough they use spider silk (notoriously known for being one of the strongest materials) while constructing their nests! Another little-known fact is that although males possess striking features like black whiskers; female black whistling vira’s also have this feature, which is not as pronounced as the males.

In summary, the Black-whiskered Vireo is a unique bird that inhabits specific areas of Central and South America during nesting seasons. They prefer lowland forests or subtropical moist areas where they consume insects with occasional fruits for added nutrition. It’s fascinating to know that these birds use spider silk while constructing their nests and both male and female black whistling vira’s possess this striking feature despite being more subtle in females than males.
