THE BIRDS OF EPPING FOREST 39 Redwing (Turdus musicus, L.).—A winter visitor. The appearance of this species is controlled by the food supply, and consequently its movements are very uneven. For example, 1922 was a notoriously good fruit year and redwings were strikingly numerous. On the other hand 1923 was as bad a fruit year as 1922 was good, and redwings were almost entirely absent. Fieldfare (Turdus pilaris, L.).—A winter visitor, but much less numerous than the redwing. The remarks on the movements of the redwing also apply to the fieldfare. Blackbird (Turdus m. merula, L.).—A common resident. Numbers very much increased in winter. Redstart (Phoenicurus p. phoenicurus, L.).—A common summer visitor. The many nesting-holes provided by the pollard trees are probably the reason of the prevalence of this species in the Forest. Average date of arrival April 17th. British Redbreast (Erithacus rubecula melophilus, Hart.).—An abundant resident. Common Nightingale (Luscinia m. megarhyncha, G. L. Brehm).— A common summer visitor. If the volume of song can be taken as a guide, the numbers of this species vary from year to year. Average date of arrival April 22nd. British Stonechat (Saxicola torquata hibernans, Hart.).—Recorded twice. Nested in 1921, and 2 ♂ s and 1 ♀ recorded from Fairmead Bottom, on September 29th, 1923. Whinchat (Saxicola r. rubetra, L.).—A scarce spring and autumn bird of passage. Wheatear (Oenanthe o. oenanthe, L.).—A scarce spring and autumn bird of passage. British Hedge-Sparrow (Prunella modularis occidentalis, Hart.).— A common resident. Wren (Troglodytes t. troglodytes, L.).— An abundant resident. Swallow (Hirundo r. rustica, L.).—A summer visitor, not too com- mon, but more so at time of autumn migration. Average date of arrival April 20th. Martin (Delichon u. urbica, L.).—As swallow. Average date of arrival May 3rd. Sand-Martin (Ripania r. riparia, L),—An occasional bird may be seen during the summer. British Great Spotted Woodpecker (Dryobates major anglicus, Hart.).—A common resident, probably increasing. The prevalence of this handsome species is a feature of the Forest. British Lesser Spotted Woodpecker (Dryobates minor comminutus, Hart.).—A well represented resident, although less numerous than the great spotted. Green Woodpecker (Picus viridis virescens, G. L. Brehm.).—A common resident, more partial to the open spaces than the other two woodpeckers. Wryneck (Jynx t. torquilla, L.). —Only records two occurrences at end of April, 1918.
