ARDEIDAE—HERONS. 185 Purple Heron : Ardea purpurea. A rare and accidental straggler to Britain, of which only one specimen is recorded as having been certainly met with in Essex. Mr. C. Walford records (19. 126) a fine specimen shot during the second week in April, 1839, in a wood near Maldon. He adds : " It was very low in flesh when killed, not weighing more than two pounds six ounces." A specimen which Selby says (British Ornithology, ii. 15, note) was killed "near London," is very likely to have been obtained in Essex, but no locality is given. Great White Heron : Ardea alba. A rare and accidental straggler to Great Britain. The only record of its appearance in Essex is the following : Messrs. Sheppard and Whitear write (9.40) :— "On the 3rd of October last [? 1823], in a walk on the bank? of the River Stour, we observed a large White Heron cross over from the Suffolk to the Essex side of the river. It appeared to be pure white, and to stand up rather taller than some common Herons which were feeding not far off. A similar bird was ob- served in the spring on the Oakley shores ; and, subsequently to our observation, one was seen on the banks of the River Orwell." Little Bittern : Ardetta minuta. A somewhat rare visitant to Britain, which has occurred at least half-a-dozen times in Essex, chiefly during the autumn or early winter. C. E. Smith, of Cogges- hall, in 1860, mentions one (31. 52) "shot by Mr. Sach of the Abbey Farm." Dr. Bree re- cords (29 ; 32a ; and 34. 517), "a male, in good plumage," shot on Aug. 13th, 1866, just above North Bridge, Colchester. He adds : " I never heard of one being captured here be- fore," and says further that it was added to his Collection. Mrs. Bree still has it. Henry Doubleday has recorded (34. 4199) that a young specimen, probably a male, having just com- pleted its first autumnal moult, was shot at Pass- ingford Bridge on Sept. 15th, 1874, after having been seen about for sev-
