A Traveler from Afar
Primarily a European bird, the Lesser Black-backed Gull breeds on the Atlantic coasts, migrating south for the winter. However, in recent decades, their populations have been increasing in North America, with Costa Rica becoming a more frequent stop on their long journeys.
These gulls are adept fliers, easily spotted soaring with their long, slender wings that can reach an impressive span of nearly 60 inches (150 cm). Their plumage is a study in cool tones – a dark grey back contrasting with a white underbelly and head. Adults have bright yellow legs and a yellow bill, which can appear dark brown with a yellow tip in younger birds.
Masters of Adaptation
The Lesser Black-backed Gull is an opportunistic omnivore, thriving on a varied diet. While fish and crustaceans are their preferred meals along the coast, their adaptable nature allows them to find sustenance in unexpected places. Here in Costa Rica, you might see them scavenging for scraps around fishing villages or following farmers as they plow fields, hoping to snatch up unearthed grubs and insects.
A Glimpse from the Mountains
Though not as common as some of our resident birds, the Lesser Black-backed Gull can occasionally be spotted from our mountain retreat. They are most likely seen near bodies of water, such as the man-made lakes or the flowing rivers that snake through the valleys. Keep your eyes peeled as you explore the lush landscape – you might just be rewarded with a sighting of this elegant traveler.
Conservation and Coexistence
The Lesser Black-backed Gull is currently listed as Least Concern by the IUCN. However, populations in parts of their European range are experiencing declines. Here in Costa Rica, their increasing presence highlights the interconnectedness of our planet’s ecosystems. By protecting healthy habitats and minimizing human impact on the environment, we can ensure that these magnificent birds continue to grace our shores for generations to come.
So, the next time you’re relaxing on your balcony at our retreat, take a moment to scan the skies. You might just be lucky enough to witness the Lesser Black-backed Gull, a testament to the wonders of avian migration and the beauty of Costa Rica’s diverse wildlife.
