78 THE ESSEX NATURALIST. coal tits and great tits. One's first impression was that leaves were being driven wildly by wind. In reality it was a calm bright day and the "leaves" were birds—chiefly bramblings. A few bramblings may sometimes be seen near the Jubilee Retreat in frosty weather. I have also heard and seen them on trees at Leppitt's Hill. Snow-Bunting. On March 13th, 1925, I saw a Snow- Bunting at High Beach. The bramblings, mentioned above, had left and there were very few birds about, when suddenly this bird, in dazzling black and white plumage, shot out from the base of the bank just below me. The Snow Bunting had not previously been recorded for Epping Forest, but as at that time there lived near-by a man who kept various birds in captivity, it may possibly have been an escape from a cage. The excellent condition of its plumage is, however, a point in favour of its having been of genuinely wild origin. Lesser Redpoll. On October 9th, 1930, among the birch trees above Dick Turpin's Cave, I saw a flock of at least fifty redpolls, clinging in tit-like fashion to the twigs. The crackling of the birch cones was audible whilst they fed and in the sunshine the crimson heads were clearly seen. Birds of the Hornbeam and Oak Forest. In typical Forest, such as Bury Wood and Hawk Wood, the Spring season is marked by the arrival of several species of migrant birds, that come for the nesting season. Those that are present in large numbers are the Chiffchaff, Willow Warbler, Garden Warbler, Blackcap, Whitethroat and Spotted Flycatcher. The Lesser Whitethroat is fairly frequent. Two species of migrants which come regularly but in small numbers are the Redstart and the Wood Warbler. When the migrants have left in the autumn, the Forest is peopled with parties of resident birds, which explore the trees and the ground for food. Amongst these are flocks of Greenfinches and Chaffinches and parties of Longtailed, Great, Blue, Coal and Marsh Titmice, Goldcrests and Treecreepers. Often such parties of small insect-eating birds are made up of several species. This year (1930) has apparently been very favourable to successful bird-rearing in Epping Forest. For a week from
