Autumn is here: the first of the post-breeding shorebirds are on their way south. At Slimbridge, while I was watching the Spoonbill, there were at least six Green Sandpipers (Tringa ochropus) feeding on the edges of the same pool. I was going to illustrate this post with my own photos, and then Vic Savery sent me this excellent shot:

Green Sandpiper is the earliest of our sandpipers to appear on southbound migration, always being seen somewhere locally from the end of June onwards, so no need to panic about winter being on the way just yet. Any freshwater wetland with reasonable areas of exposed mud will be graced by Green Sandpipers over the next few months. The birds turning up at the moment are adults, whereas juvenile birds will occur from August onwards (a pattern common to most migrant shorebirds). Green Sandpipers also overwinter in the region in moderate numbers, tending to inhabit shallow slow-flowing streams and ditches and marshy sites.
Green Sandpipers nest in bogs from Scandinavia eastwards through Russia. Unusually for a shorebird, they nest in trees, in disused birds nests. Occasionally, pairs nest in Scotland. A lookalike species, Solitary Sandpiper (Tringa solitaria), replaces Green Sandpiper in North America. They have occured in southwest England after Atlantic storms in autumn several times, usually on the Isles of Scilly, but there was one in Devon a few years ago, so it’s possible that one could turn up near Bristol one day.
Here are a couple of my own Green Sandpiper photos as well, showing a Slimbridge bird in some different poses, and highlighting how birds can look different in different lighting conditions. You can also see, by looking closely at individual feathers, that this is a different bird from the one Vic photographed.
