We have noticed that local birds tend to choose grassland of about 30cms in length that is long enough to hide in, but short enough to look out of if necessary. Adults need to be able to hide safely as well as lookout over the vegetation during the early stages of nesting when they are more visible.
The nest is a shallow indentation in the grass. It is made by the curlew swivelling and pressing down its chest. Dead or dry grass is left or added at the bottom.
