150 THE BIRDS OF ESSEX. last I saw was a few weeks ago, when one flashed out like a streak of blue light- ning from a ditch close to the Forest Hotel at Chingford." In May, 1880, a nest of young ones was reared in a hole in the bank of the brook Slade in the park at Audley End, in a position exposed to the view of every one passing along the public footpath running through the park. The nest itself was perfectly clean, but the hole was full of filth, which even streamed down the bank from the entrance. They certainly breed here in the banks of the brook Cann, as I see them about every summer. On July 21st, 1876, a party of three flew very close to me as I was bathing. I believe it is not common to see more than one, or at most a pair, at once. Mr. Hope, who has reared young from the nest, has met with it breeding all over Essex, but says fresh arrivals take place on the coast about September. At Harwich " it is fairly common in the autumn" (Kerry). In the Orsett district it is a winter visitor only, frequenting the fens, and saltings (Sackett). It nests every year in the floodgate hole at Baythorne Mill, Birdbrook (Fitch). Roller: Coracias garrula. A rare straggler to Britain, of which only a single specimen, so far as I know, has occurred in Essex. In the Museum at Saffron Walden is a specimen shot at Great Chesterford Park in 1865, and presented by Geo. Sanders, Esq. Presumably the specimen mentioned by Yarrell (37. ii. 429) is identical with this. One, caught at " Rain- ham " in 1889 (40. xiii. 33), was taken at the village of that name in Kent, not in Essex. Bee-eater: Merops apiaster. This rare straggler to Britain during summer has been met with at least twice in Essex. Mr. Thomas Catchpool records one (23. 4478) "shot in the garden of a mill close by the river's side in the parish of Feering * * * [not " Festing" as stated by Yarrell (37. ii. 36)] about Midsummer Day [1854] " which came into his pos- session (31. 53). Mr. Buxton mentions one (47. 89) "observed at Wanstead by H. I." Family UPUPIDAE. Hoopoe : Upupa epops. An uncommon, though, it may almost be said, a regular, passing migrant in both spring and autumn. Its appearance in Essex in the spring seems usually to take place between April 15 th and May 7th: in autumn, during September, though instances are recorded of its appearance in autumn as early as August 7th, and as late as October 9th. The occurrence in Essex of at least one specimen is,
