The Wren is a tiny brown bird, although it is heavier and not as slim as the even smaller Goldcrest. For such a small bird it has a remarkably loud voice.
The name derives from Old English sand-yrðling, “sand-ploughman”.
The Sanderling (Calidris alba) is a small wading bird.
It is highly gregarious in winter, sometimes forming large flocks on coastal mudflats or sandy beaches.
This bird is similar in size to a Dunlin, but stouter, with a thick bill.
Oystercatchers are large and noisy plover-like birds, with massive long orange or red bills.
The different species of Oystercatcher show little variation in shape or appearance.
The plumage of all species is either all-black, or black (or dark brown) on top and white underneath.
They show sexual dimorphism, with females being longer-billed and heavier than males.
