While our mountain retreat offers breathtaking views of the Costa Rican highlands, a whole other world exists just beyond the horizon – the vast expanse of the Pacific Ocean. Today, we set our sights on a creature that calls this watery realm home: the Audubon’s shearwater.

Tropical Travelers:
Unlike many of the birds you’ll encounter at our retreat, the Audubon’s shearwater (Puffinus lherminieri) is a true globetrotter of the skies. Though they nest on islands throughout the Caribbean and across the Pacific, these birds spend most of their lives soaring above the ocean waves. Their range extends as far north as the Gulf Stream and the Arabian Sea, making them a bird of truly tropical waters.
Masters of the Wind:
The Audubon’s shearwater is a marvel of avian adaptation. Their long, slender wings, designed for effortless gliding, allow them to exploit updrafts and currents over the ocean, barely needing to flap their wings. This skimming flight technique, coupled with webbed feet for paddling, makes them graceful dancers on the surface of the water when taking off or landing.
Dusky Beauties:
While not the most vibrantly colored bird, the Audubon’s shearwater possesses a certain elegance. Their dark chocolate brown back contrasts beautifully with their white underbelly, giving them a tuxedo-like appearance in flight. Their eyes are dark and beady, perfectly suited for spotting prey in the open ocean.
A Life at Sea:
As with most seabirds, the Audubon’s shearwater spends most of its life far from land. They come ashore only to breed, nesting in burrows on islands or coastal cliffs. Their diet consists mainly of fish, squid, and crustaceans, which they snatch up from the water’s surface while skimming or by diving from short heights.
A Glimpse from the Coast:
While you won’t find the Audubon’s shearwater soaring through the mountain air around our retreat, avid birders venturing to Costa Rica’s Pacific Coast may be lucky enough to spot them. Boat tours or pelagic birding trips offer the best chance of encountering these remarkable seabirds.
A Call to Conservation:
The Audubon’s shearwater, though currently classified as “Least Concern” by the IUCN, faces threats like habitat loss due to invasive predators on nesting islands and pollution in the oceans. By supporting organizations dedicated to seabird conservation, we can help ensure these magnificent birds continue to grace the skies for generations to come.
So, the next time you find yourself gazing out at the vast Pacific Ocean, remember the incredible creatures that call it home. The Audubon’s shearwater, a tireless traveler and master of the open sky, is a testament to the wonders that exist beyond our mountain sanctuary.
