While our mountain retreat offers stunning views of the Costa Rican highlands, spotting a resident of the open ocean might seem like a long shot. But fear not, bird enthusiasts! Today, we turn our gaze skyward to a remarkable visitor gracing our Pacific shores – the Pink-footed Shearwater (Ardenna creatopus).
A Globetrotting Guest
Imagine a bird with a wingspan stretching over a meter, effortlessly gliding on air currents. That’s the Pink-footed Shearwater, a true master of long-distance travel. These incredible birds breed on islands off the coast of Chile, but their migratory journeys take them across the equator, with some individuals reaching the waters off the west coast of North America, including Costa Rica.
Spotting a Seafarer
While primarily an oceanic bird, Pink-footed Shearwaters can occasionally be spotted from the shores of Costa Rica, particularly during the northern hemisphere’s summer months (roughly May to September). Joining pelagic birding tours, which venture further offshore, offers the best chance of encountering these magnificent creatures.
Look for These Clues
So, how do you identify a Pink-footed Shearwater amidst the vastness of the ocean? Here are some key features:
- Size and Shape: Measuring around 48 cm in length, this shearwater boasts a long, slender body and impressive wingspan (around 109 cm).
- Coloration: Look for a bird with a brown back and white underparts. Some individuals may have a darker overall plumage.
- Flight Style: Pink-footed Shearwaters are graceful gliders, often utilizing updrafts to stay aloft with minimal effort. They exhibit a characteristic dipping flight pattern, skimming close to the water’s surface before rising again.
A Life on the Ocean Waves
Pink-footed Shearwaters are true specialists when it comes to life at sea. They feed by diving for small fish, squid, and crustaceans, often following fishing boats to snatch up scraps. Their webbed feet propel them underwater, while their streamlined bodies allow for efficient swimming.
A Cause for Concern
Sadly, the Pink-footed Shearwater faces several threats. Introduced predators like rats and cats on nesting islands pose a significant danger. Additionally, bycatch in commercial fishing operations can take a toll on their populations. The IUCN currently classifies them as Vulnerable, highlighting the need for conservation efforts.
A Glimpse into a Different World
Spotting a Pink-footed Shearwater during your Costa Rican retreat is a rare and unforgettable experience. It’s a chance to connect with a creature that embodies the vastness and wonder of the ocean. While our mountain retreat offers a haven for birds of the forest, keep your eyes peeled towards the horizon – you might just encounter a magnificent visitor from the other side of the world.
