A tale of two plumages:
The White-flanked Antwren is a master of disguise, with two distinct plumages depending on its sex. Males are the stars of the show, adorned with a sleek black coat with contrasting white markings. A bold white patch adorns their flanks, hence their name. Their wings are adorned with white spots, and even their tail feathers have white tips.
Females, on the other hand, opt for a more subdued look. They are dressed in soft gray-brown plumage with a touch of cinnamon spots on the wings. However, the revealing white flanks still peek through, making them identifiable even in their most sober attire.
A busy life in the forest:
These small active birds are rarely seen alone. They usually feed in pairs or join mixed-species flocks, flitting through the undergrowth in search of their next meal. Their short, sharp beaks are perfectly adapted to catching small insects like ants, spiders, and caterpillars.
The White-flanked Antwrens are experts at collecting insects from leaves and branches, but they also demonstrate impressive aerial skills. They can be seen darting into short flights to catch prey in the air, adding a touch of acrobatics to their foraging routine.
Where to find them?
The White-flanked Antwren is a widespread resident of Costa Rica, found on both the Caribbean and Pacific slopes. They thrive in a variety of forest habitats, from lowland rainforests to the foothills of mountains.
