Here at our Costa Rican retreat, nestled amidst the verdant embrace of the mountains, we’re surrounded by a symphony of life. Among the vibrant flora and the rustling leaves, some of nature’s most dazzling residents flit by – the hummingbirds. Today, we turn our gaze to a tiny emerald wonder, the White-tailed Emerald (Elvira chionura).

This miniature marvel is a true resident of the highlands. Unlike some hummingbird species that grace the Central Valley, the White-tailed Emerald prefers the cooler, subtropical or tropical moist montane forests. So, if you’re venturing on hikes or nature walks during your stay at our mountain retreat, keep your eyes peeled for this dazzling creature.

The White-tailed Emerald is a feast for the eyes. Males boast an iridescent emerald green plumage that shimmers like a polished gemstone in the sunlight. This brilliance extends across their bodies, except for the striking contrast of their bright white lower belly and the outermost tail feathers. The effect is breathtaking – a tiny emerald darting through the air, leaving a trail of white behind it.

Females share a similar emerald shimmer, but their white extends further up their bodies, often reaching the throat. Both sexes have short, slightly decurved bills, perfectly adapted for reaching the nectar of the mountain flowers they favor.

While they might be tiny, at under 3 grams, White-tailed Emeralds are bursting with energy. They flit from flower to flower, their wings beating so rapidly they appear almost invisible. This rapid wingbeat allows them to hover mid-air, extracting nectar with their long, slender bills. Watching them feed is a mesmerizing dance of color and movement.

If you’re fortunate enough to spot a White-tailed Emerald during your stay, take a moment to appreciate this tiny ambassador of the Costa Rican mountains. Their frenetic energy and dazzling plumage are a true testament to the wonders that flit through our rainforests.

Tips for Spotting the White-tailed Emerald:

• Early mornings and late afternoons: These times tend to be more active feeding periods for hummingbirds.
• Near flowering plants: Look for flowers with red or orange colors, which tend to attract hummingbirds.
• Listen for their buzzing: The rapid wingbeat of hummingbirds creates a distinctive buzzing sound.
• Be still and patient: Hummingbirds are skittish creatures. Remain calm and still to increase your chances of spotting one.

With a little patience and a keen eye, you might just be rewarded with a glimpse of this sparkling jewel in the heart of the Costa Rican mountains.
