TURDIDAE—WARBLERS. 85 the year, especially in the Wanstead Park Woods." It breeds not uncommonly in both the Colchester and Paglesham districts (Laver), At Harwich it is scarce during the breeding season, though often numerous during migration (Kerry). Mr. Hope writes : Migratory individuals arrive " on the Essex coast in vast flocks and singly about the 10th of October ; I have had them fly aboard when off the Sunk lightship, so tame that they would hop all over one, apparently looking for water to drink ; it breeds at Havering." Fire-crest: Regulus ignicapilius. A rare and accidental visitor. A specimen " taken by a bird- catcher, at Epping, 26th Novem- ber, 1878, is preserved * * * in the British Museum " (Buxton—47. 91). Mr. J. H. Gurney, jun., records (40. 225) 1888, the occurrence of five specimens (three of which are in the possession of a Mr. Thos. Sorrell) in the month of November, some years ago, among about seventy Gold- crests taken on the Galloper L.V. Mr. E. R. Green, of Ilford, informs me that he shot specimens " in a small wood close to Barking Side," but, fire-crest, 1/2. though preserved, they were accidentally destroyed. Chiffchaff: Phylloscopus rufus. Locally, "Oven-builder." A regular summer visitant, though by no means common and decidedly local in Essex. Its name is derived from its familiar note. Of all our spring migrants, it is the earliest to arrive, being sometimes heard before the middle of March. In 1878, Dr. Bree both saw and heard it in his garden at Colchester, as early as March 5th (29. Mar. 9). In 1881, I heard the first on April 4th, near Audley End. In 1883, I did not hear the first here until April 7th. At Sudbury, it is only a very occasional visitor (Grubb—39). Round Pagles- ham it is common (Wiseman). Round Harwich it is also " common," and may be heard every spring in the Wrabness woods (Kerry). It is common in both the Colchester and Paglesham districts (Laver). In the extensive woods about Danbury and in the Writtle and Blackmore Highwoods, it is fairly abundant, but I have never once heard its note round my own home, at Chignal St. James, for several years past. Mr. Sackett has taken undoubted eggs at Orsett. Willow-Warbler: Phylloscopus trochilus. A very common summer visitor, arriving usually about the first week in April, and remaining until the middle of September. It breeds, I believe, abundantly throughout the county. It is very
