                                                  curved trailing edge than Grey Heron’s, neck creating
                                                  deeper bulge, larger feet sometimes obvious.
           uch more of a reedbed bird than the Grey
        MHeron, the Purple Heron is consequently
        more difficult to see unless it flies over the reeds or
        chooses to feed at the edge of a reedy pool. It
        breeds in small groups, but is generally a less social
        bird than most herons. It has often been predicted
        that the Purple Heron will spread north and breed
        in the UK, but this has so far failed to develop: it
        remains a rather rare visitor north of its usual range.
        VOICE Short, simple, harsh krekk.
        NESTING Large pile of reed stems and other
        vegetation, often in reeds, sometimes in trees; 4 or 5
