The green sandpiper (Tringa ochropus) is a small wader (shorebird) of the Old World. The green sandpiper represents an ancient lineage of the genus Tringa; its only close living relative is the solitary sandpiper (T. solitaria). They both have brown wings with little light dots and a delicate but contrasting neck and chest pattern. In addition, both species nest in trees, unlike most other scolopacids.
Given its basal position in Tringa, it is fairly unsurprising that suspected cases of hybridisation between this species and the common sandpiper (A. hypoleucos) of the sister genus Actitis have been reported. The green sandpiper was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the current binomial name Tringa ochropus. The genus name Tringa is the Neo-Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific ochropus is from Ancient Greek okhros, "ochre", and pous, "foot". The species is monotypic: no subspecies are recognised.

Possible
About 30% of wildlife watchers report a Green Sandpiper sighting in Vasai-Virar on a given day, based on 406 verified sightings from GBIF citizen-science data. It is the 47th most-seen of the 217 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
October to March
In those months about 40% of wildlife watchers report a Green Sandpiper in Vasai-Virar on a given day, against under 5% in May–June and August, the lowest months. Those are among Vasai-Virar's driest months, with about 20 mm of rain a month against 840 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Green Sandpiper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 143 cities where we can rate Green Sandpiper sightings, Vasai-Virar has the highest daily chance: about 30%. Next come Xi'an (China, about 20%) and Kathmandu (Nepal, about 20%).
Same genus: Tringa
The closest relatives of the Green Sandpiper that you can see in Vasai-Virar (genus Tringa, Shanks, Tattlers, and Allies) are Wood Sandpiper (about 40%), Marsh Sandpiper (about 10%) and Common Greenshank (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green Sandpiper is recorded against all the birds logged in Vasai-Virar (406 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
