While our mountain retreat offers stunning views and a symphony of rainforest sounds, Costa Rica boasts an incredible diversity that extends far beyond the jungle’s embrace. Today, we take a virtual journey to the sun-drenched shores of the Caribbean coast, where a fascinating bird, the Black Skimmer, graces the turquoise waters with its unique technique.

A Striking Appearance:

Imagine a tern-like bird dipped in black and white paint. The Black Skimmer (Rynchops niger) is a medium-sized seabird, measuring 16-20 inches in length with a wingspan reaching a remarkable 42-50 inches. Its plumage is a study in contrasts – a sleek black cap, nape, and upper body brilliantly offset by a snowy white forehead and underparts. But the most striking feature is undoubtedly the bill. Unlike any other bird, the Black Skimmer possesses a long, lower mandible that extends far beyond the upper one. This seemingly odd adaptation holds the key to their remarkable feeding strategy.

Skimming the Surface for Dinner:

The Black Skimmer’s claim to fame lies in its one-of-a-kind hunting technique. They are the only birds on Earth that feed by skimming! With their long lower mandible cutting through the water’s surface like a plow, they fly low over the waves with their bills open. Their keen senses detect the presence of small fish brushing against the mandible, triggering a lightning-fast snap that scoops up the unsuspecting prey. This incredible adaptation allows them to hunt even in low-light conditions, making them active at dawn, dusk, and sometimes even at night.

A Coastal Charmer:

While you won’t find Black Skimmers soaring over our mountaintop retreat, a trip to Costa Rica’s Caribbean coast offers the chance to witness their graceful skimming technique. Popular spots include Tortuguero National Park, Barra del Colorado Wildlife Refuge, and Cahuita National Park. Here, you might see them gracefully gliding along the coastline, their red legs flashing as they take flight, or witness them congregating in noisy colonies on sandy beaches, their calls – a series of barking “kak-kak-kaks” – adding to the coastal ambiance.

Black Skimmers – More Than Just a Pretty Bill:

These fascinating birds play a vital role in the coastal ecosystem. By preying on small fish, they help maintain a healthy balance in the marine food web. Their presence also serves as an indicator of a healthy coastal environment, reminding us of the importance of protecting these fragile ecosystems.

Witnessing the Wonders of Costa Rica:

While the Black Skimmer might not grace our mountain retreat, their presence on the Caribbean coast adds another layer to the incredible biodiversity of Costa Rica. As you explore this beautiful country, keep an eye out for these unique birds – their specialized technique and striking appearance are sure to leave a lasting impression.

Who knows, maybe on your next Costa Rican adventure, you’ll find yourself captivated by the Black Skimmer’s dance with the sea!
