ITS BIRDS 79 Wanstead Park and elsewhere. In the " Sixties" they used to breed on Fairmead and near the Wake Arms, but have ceased to do so. They are now seldom seen within the Forest, but there are some fields just outside its limits to which they still resort in spring. Landrail or Corncrake. A summer visitor nesting and remaining till the middle of September. Water-rail. Not so rare as is sometimes supposed. Owing to their silence and habit of creeping along the sides of brooks, and rarely taking to the water, they are not often seen ; but they are sometimes very noisy in the breeding season. Heron. These birds come to the heronry in Wanstead Park HERONS. at the end of January or beginning of February, and at once begin nesting operations. The old nests seem to require little repair. The number of nests for the last twenty years was as follows :—1882, 40 ; 1883, 36 ; 1884, 41 ; 1885, 45 ; 1886, 48 ; 1887, 46 ; 1888, 49 ; 1889, 51; 1890, 53; 1891, 50; 1892, 56; 1893, 61 ; 1894, 68 ; 1895, 55 ; 1896, 53 ; 1897, 48 ; 1898, 50 ; 1899, 50 ; 1900,48; 1901,45. The young birds may be heard in the nests early in March. The birds do not seem to mind the people, but I think there is some danger of their being evicted by the rooks, which have greatly increased of recent years. They are continually fighting the herons in the air, and instances are not unknown of a heronry being driven out in this way. The greater number of these birds leave the heronry towards the middle of summer, but a few remain throughout the year.
