While most of our birding adventures at the retreat focus on the vibrant residents of the Costa Rican rainforests and mountains, today we set our sights on a true globetrotter – the Sooty Shearwater. Though not a permanent resident, these incredible birds grace our Pacific shores during their epic migrations.
The Sooty Shearwater, also known as the Tīti or Muttonbird, is a medium-sized seabird with a dark brown coat and silvery flashes on its underwings. These unassuming birds are anything but ordinary. Buckle up, as we delve into the fascinating life of this avian marvel.
Masters of the Skies and the Seas
Sooty Shearwaters are champions of flight, utilizing wind currents to soar effortlessly over the ocean. Their stiff wingbeats propel them across vast distances, making them some of the world’s most impressive long-distance migrants. Imagine this – a Sooty Shearwater can travel up to 40,000 miles in a single year, tracing a figure-eight pattern across the Pacific and Atlantic Oceans!
But their talents extend beyond gliding. Sooty Shearwaters are adept divers, plunging deep into the ocean depths in pursuit of fish and other marine creatures. With their wings tucked close, they propel themselves underwater, reaching depths of up to 220 feet – an impressive feat for a bird!
A Southern Soul with a Northern Heart
Sooty Shearwaters breed on islands in the Southern Hemisphere, including New Zealand and the Falkland Islands. However, their nesting season coincides with our Costa Rican dry season (December to April). This is when these incredible birds embark on their incredible journey north, gracing our Pacific shores with their presence.
While not as commonly spotted as some resident birds, Sooty Shearwaters can be seen off the Pacific coast of Costa Rica, particularly near the Gulf of Papagayo and the Osa Peninsula. With a bit of luck, you might catch a glimpse of these magnificent birds gliding effortlessly over the waves, a fleeting reminder of the wonders that lie beyond our mountainous haven.
Ambassadors of a Fragile World
The Sooty Shearwater population, though abundant, is classified as Near Threatened by the IUCN. Habitat degradation, climate change, and threats from invasive predators all pose challenges to these remarkable birds.
So, the next time you spot a Sooty Shearwater gliding over the Costa Rican Pacific, take a moment to appreciate this ambassador of the vast oceans. Their presence is a reminder of the interconnectedness of our planet and the importance of protecting the delicate balance that sustains all life.
