Charadrius semipalmatus
The Semipalmated Plover, a small but charismatic shorebird, is a marvel of long-distance migration and adaptation. Measuring approximately 14-20 cm (5.5-8 inches) in length with a wingspan of 45-50 cm (17.5-20 inches) and weighing 35-50 grams (1.2-1.8 oz), this species is characterized by its brownish-grey upperparts, pristine white underparts, and a single, prominent black breast band. Its most distinctive field marks include bright yellow-orange legs, a short, thick bill that is black with ...
This plover primarily inhabits open coastal areas, mudflats, and shorelines during migration and winter, transitioning to tundra and open gravelly areas for breeding in the Arctic.
Their diet consists almost exclusively of small marine and aquatic invertebrates, including marine worms, various crustaceans (such as amphipods and copepods), and a wide array of insects and their larvae.
Semipalmated Plovers are diurnal foragers, often seen resting in small, loose flocks during high tide or at night. Their foraging strategy is a classic 'stop-run-peck' technique, where they sprint a short distance, abruptly stop to visually locate prey, then quickly peck it from the surface or ju...
The Semipalmated Plover boasts an expansive geographic distribution, breeding across the Arctic and subarctic regions of North America, from western Alaska, across the Canadian Arctic Archipelago, Greenland, and south to parts of Newfoundland and Labrador. Their epic migration routes take them ac...
Least Concern
- The name "Semipalmated" refers to their partially webbed feet, a unique adaptation among plovers that helps them walk on soft, muddy substrates without sinking. - They are one of North America's longest-distance migrant shorebirds, traveling from the Arctic tundra to as far south as Patagonia a...
