Solitary Sandpiper

Tringa solitaria

The solitary sandpiper is a small shorebird. 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 solitaria is Latin for "solitary" from solus, "alone". Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 22°C (typically 15 to 28°C, from 35 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 North America ranged from 13°N in September to 43°N in July, about 3,400 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.
