ITS BIRDS 71 Redwing. Large numbers roost in the denser thickets dur- ing hard winters, especially when there is a good supply of holly and other berries. At sunset they come troop- ing in from all quarters, and sweep round the trees in graceful flight before settling down for the night in the lower brushwood. Fieldfare. In hard weather they come close to the houses to feed on holly berries. Missel Thrush. Common. His grating note is heard in Wanstead Park in mid-winter and the early months. Wryneck. Comes with the cuckoo, and is frequently heard in April, but soon leaves us for the more retired parts of the Forest. Green Woodpecker. May be constantly heard tapping, and occasionally seen, in the northern part of the Forest. Very frequent about Cook's Folly, near Walthamstow. GREEN WOODPECKER. Greater Spotted Woodpecker. Fairly common in several parts. The rattling of his beak on a hollow branch is audible at a long distance. Lesser Spotted Woodpecker. "Three times seen in my garden at Leytonstone."—A. L. Not very uncommon in the Forest. Nuthatch. Generally found in the neighbourhood of old elm trees. In such positions, if supplied with nuts, they carry them off every morning, invariably leaving unsound ones, '' Many years ago a pair used to come to my whistle every morning to be fed at an old mul- berry tree in my garden. They would run down the branch to within a yard of my outstretched hand, but never quite ventured to take the nuts I offered them until I laid them down.''—A. L. Hoopoe. More than one example of this rare bird has been observed in the neighbourhood. One bird frequented a garden at Knotts Green for several days some years ago.
