Common Greenshank

Tringa nebularia

The common greenshank is a wader in the large family Scolopacidae, the typical waders. 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 nebularia is from Latin nebula "mist". Like the Norwegian Skoddefoll, this refers to the greenshank's damp marshy habitat. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 12°C (typically 8 to 19°C, from 21 areas). That range is wide, so temperature alone does not explain when it turns up.

Over the weeks it was present in the past year, its centre in Europe ranged from 43°N in October to 66°N in June, about 2,600 km apart.

Arrival dates

The week it was first heard regularly in each region, after at least six weeks away. Dates differ from south to north, so a region has a range.
