10-10-2017 - VILLALONGA RESERVOIR, VALENCIA - GREEN SANDPIPER (Tringa ochropus)

The Green Sandpiper, Tringa ochropus, is a small wader, or shorebird, with a somewhat plump appearance. It boasts a dark greenish-brown back and wings, complemented by a greyish head and breast. The underparts are predominantly white, with the back featuring white spots that vary in extent depending on the season and age of the bird. The legs and short bill are a matching dark green, creating a harmonious color palette for this avian species.

When observing the Green Sandpiper, look for its distinctive flight pattern, which reveals dark wings above and below, punctuated by a striking white rump. This feature is a reliable identifier, setting it apart from its close relative, the slightly smaller Solitary Sandpiper of North America. Additionally, the Green Sandpiper's white-spotted back is most pronounced in breeding adults and less so in winter and juvenile plumage.

The Green Sandpiper is a freshwater aficionado, often found in more confined spaces than other waders, which typically prefer open vistas. It thrives in a variety of freshwater habitats, avoiding the more gregarious nature of some wader congregations.

This bird breeds across subarctic Europe and extends its range east across the Palearctic. It is migratory, seeking winter respite in southern Europe, the Indian Subcontinent, Southeast Asia, and tropical Africa.

The Green Sandpiper is not known for its sociability, as it is rarely seen in large groups. It prefers to forage alone, methodically picking small invertebrate prey from the mud along the edges of ponds and streams.

In flight, the Green Sandpiper emits a characteristic three-note whistle, which can be heard over the quiet waters it frequents.

A unique nester among waders, the Green Sandpiper lays 2 to 4 eggs in the abandoned arboreal nests of other bird species, such as the Fieldfare. The eggs incubate for approximately three weeks before hatching.

The Solitary Sandpiper (T. solitaria) is the Green Sandpiper's closest living relative and the most similar in appearance. However, the Solitary Sandpiper can be distinguished by its smaller size and different geographical range, being native to North America.

The diet of the Green Sandpiper consists of small invertebrates, which it diligently collects from the muddy edges of its freshwater habitat.

The IUCN classifies the Green Sandpiper as Least Concern, indicating a stable global population. It is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA), ensuring concerted efforts for its conservation.
