Here at our Costa Rican retreat, nestled amidst the emerald embrace of the mountains, we’re surrounded by a symphony of sights and sounds. Among the colorful orchestra of birds that grace our grounds is the aptly named White-lined Tanager, a species with a fascinating story written in its plumage.
A Dimorphic Dance:
The White-lined Tanager (Tachyphonus rufus) is a captivating member of the Thraupidae family, known for their vibrant displays. But this particular tanager takes dimorphism – the presence of distinct male and female appearances – to a whole new level.
Imagine a dapper gentleman clad in all black, with perhaps a hint of white peeking out from his shoulder – that’s the male White-lined Tanager. His plumage is a study in stark contrast, a sharp silhouette against the lush greenery. The white patch, however, is often quite subtle, a mere sliver that might go unnoticed by the casual observer.
The female, on the other hand, is a vision of rich, rufous brown. Her feathers lack the dramatic flair of the male, but hold a beauty all their own. Both sexes, however, share a sturdy, pointed bill, a common feature among tanagers and a hint to their likely insectivorous diet.
Habitat Hopping:
While the White-lined Tanager has a sizeable range stretching from Costa Rica all the way down to northern Argentina, it’s not a bird of the deep rainforest. Look for them instead in the open areas we have here at the retreat – shrublands, second growth forests, and forest edges are their preferred stomping grounds.
These are social butterflies (well, maybe tanagers!), often found in pairs or even flitting about in mixed-species flocks. Keep your eyes peeled as they hop from branch to branch, their black and rufous forms a delightful flash of color against the verdant backdrop.
A Song Unsung:
Information on the White-lined Tanager’s vocalizations is somewhat limited, but some sources describe their call as a high-pitched, whistled “whee-tee.” While not the most elaborate song in the avian repertoire, it likely serves its purpose in communication within their social groups.
Spotting Your Snowy-Shouldered Suitor:
If you’re here at our retreat and eager to catch a glimpse of the White-lined Tanager, keep an eye out for them in the open areas around the lodge. Patience and keen observation are key – their subtle plumage might make them easy to miss at first glance. But with a little focus, you might just be rewarded with the sight of this little black and rufous wonder flitting amongst the leaves.
So, the next time you’re here at our Costa Rican haven, take a moment to appreciate the diverse avian cast that graces our grounds. The White-lined Tanager, with its contrasting plumage and social spirit, is a small but captivating part of the incredible biodiversity that Costa Rica has to offer.
