As we delve into the scientific realm, we encounter the enigmatic Calidris ruficollis, the Red-necked Stint—a species etched into the tapestry of avian diversity. This tiny shorebird boasts a distinctive lineage, with alternate names emerging from different corners of the world. Ornithologists recognize it as Tringa ruficollis and Erolia ruficollis in various scientific texts, each name reflecting a chapter in its taxonomic history.

Alternate Names and Taxonomic Synonyms

Throughout the annals of ornithological research, the Red-necked Stint has acquired a constellation of alternate names, each reflecting its unique characteristics and regional dialects. Ruff-necked Sandpiper and Red-necked Sandpiper are popular monikers that highlight its distinctive reddish-brown plumage. Tringa ruficollis remains the scientific synonym most frequently employed in older literature, a testament to the species’ historical classification within the genus Tringa.

Physical Appearance of the Red-necked Stint: A Tiny Agile Shorebird

The Red-necked Stint, a small and distinctive shorebird, captivates with its unique physical attributes. Measuring just 14-16 cm in length, this diminutive bird has a _weight of around 20-30 grams_ and a _wingspan that extends up to 35 cm_.

Despite its petite size, the Red-necked Stint boasts an unmistakable plumage. Its reddish-brown neck, which lends it its name, stands out against the contrasting black, white, and gray patterns of its body. Its _upperparts are adorned with mottled black and white feathers_, while its _underparts and rump are predominantly white_.

The bird’s bill is relatively short and straight, with a black tip that contrasts with the orange-yellow base. Its legs, which are typically a deep olive-green, add to its overall coloration. During breeding season, the male Red-necked Stint exhibits a _dark chestnut breast and belly with a bold white stripe down the center_. This striking plumage helps attract mates and establish territories.

Habitat and Range of the Red-necked Stint

The Red-necked Stint (Calidris ruficollis), a diminutive shorebird, inhabits diverse wetland ecosystems. During its breeding season, it sojourns in the Arctic tundra, seeking out shallow pools, marshy areas, and freshwater wetlands. In these pristine environments, the stint flourishes, its reddish-brown neck and contrasting plumage providing camouflage amidst the verdant surroundings.

As winter approaches, the Red-necked Stint embarks on an epic journey, migrating south to warmer climes. Its extraordinary adaptability allows it to thrive in various habitats, including mudflats, saltmarshes, and estuarine environments. From the vast coastal plains of Europe to the wetlands of Australia and New Zealand, this resilient bird adapts to diverse landscapes.

Its extensive wintering range encompasses a multitude of locations, including tropical mudflats, mangrove swamps, and coastal lagoons. In these habitats, the Red-necked Stint forages for its preferred prey, invertebrates, and nimbly navigates the varying conditions.

Diet and Feeding Behavior of the Red-necked Stint

The unassuming Red-necked Stint, a diminutive shorebird, possesses a remarkable appetite for the tiny creatures that inhabit its watery realm. As a true omnivore, it savors a wide range of invertebrates, including insects, crustaceans, mollusks, and worms.

Stealthy and agile, the Red-necked Stint scours mudflats and shallow waters, its specialized beak an ideal tool for probing the sediment. It deftly extracts its prey, utilizing its sensitive bill to locate and capture hidden treasures. This highly efficient feeding technique allows it to capitalize on the abundant invertebrate populations found within its habitat.

One remarkable adaptation of the Red-necked Stint is its ability to switch between feeding strategies based on prey availability. When food is scarce, it employs a technique called pecking, using its sharp bill to rapidly peck at the surface of the water to catch unsuspecting prey. In contrast, when prey is abundant, it engages in probing, inserting its bill deep into the mud to locate buried invertebrates.

With its versatile diet and adaptable feeding behaviors, the Red-necked Stint thrives in various wetland environments. Its ability to capitalize on diverse food sources ensures its survival and contributes to its widespread distribution across the globe.

Conservation Status: A Delicate Balance for the Red-necked Stint

Despite its Least Concern classification by the IUCN, the Red-necked Stint faces certain challenges that may impact its population stability. Like many shorebirds, its existence is intertwined with the preservation of its habitats, which include wetlands, mudflats, and saltmarshes. These areas are often threatened by human activities such as coastal development, pollution, and climate change.

Habitat loss and degradation can lead to reduced breeding and feeding grounds, impacting the Stint’s reproductive success and overall population numbers. Furthermore, environmental factors like rising sea levels and extreme weather events can displace entire colonies, forcing them to search for suitable nesting sites.

Another concern for the Red-necked Stint is the potential impact of hunting in some parts of its range. While hunting isn’t widespread, local practices and traditional uses can affect their survival. Additionally, changes in food availability due to climate change or shifts in invertebrate populations can influence the Stint’s health and reproductive capabilities.

Preserving the habitats used by the Red-necked Stint and implementing sustainable coastal management practices are crucial for safeguarding its future. Reducing pollution, mitigating the effects of climate change, and promoting responsible hunting practices are essential steps in ensuring the survival of this resilient yet vulnerable shorebird.
