Here at Hotel Rivel, nestled amidst the emerald embrace of the Costa Rican mountains, we’re surrounded by a breathtaking symphony of nature. But while vibrant quetzals and toucans steal the show, there are hidden gems waiting to be discovered by the keen-eyed adventurer. Today, we turn our gaze to a fascinating winter visitor, the Lesser Scaup.

The Lesser Scaup (Aythya affinis) is a small diving duck, a true globetrotter that migrates all the way from North America to grace our Costa Rican waters during the winter months. This shy beauty is a sight to behold, with the males sporting a sleek black and white coat, a contrasting bright yellow eye, and a distinctive peaked head that sets them apart from their close relative, the Greater Scaup. The females are a study in understated elegance, with a rich brown plumage and a white patch at the base of the bill.

Unlike many ducks that dabble at the water’s surface, Lesser Scaup are adept divers. They disappear with a graceful plunge, venturing deep underwater to search for their favorite food – mollusks like mussels and clams. Their diet also includes aquatic plants and small fish, making them important players in maintaining the delicate balance of the ecosystem.

While Lesser Scaup can be found in various freshwater habitats back in their North American breeding grounds, here in Costa Rica, they seem to have a particular fondness for the calm waters of larger lakes and lagoons. If you’re lucky enough to spot a flock on your next birding adventure around Hotel Rivel, keep an eye out for their characteristic behavior. They often rest in dense groups, occasionally tipping their heads underwater in a rhythmic bobbing motion as they search for food. Their flight is strong and direct, with rapid wingbeats that create a distinctive whistling sound.

The presence of the Lesser Scaup in Costa Rica is a testament to the interconnectedness of our planet. Their long-distance migration highlights the importance of preserving healthy ecosystems across vast geographical regions. Here at Hotel Rivel, we’re committed to sustainable practices that protect the habitats of these remarkable visitors.

So, the next time you’re exploring the serene lakes around our hotel, keep an eye out for the Lesser Scaup. With a little patience and a keen eye, you might just be rewarded with a glimpse of this beautiful avian gem from afar.
