74 THE BIRDS OF ESSEX. the back are white, with a few coloured feathers intermixed ; lower part of back much lighter than usual ; upper tail-coverts nearly white ; tail feathers as usual, except that two on each side and one near the middle, are white; under parts white, except for a few coloured feathers on the throat and the usual darkly- marked feathers on the sides of the breast ; wing-coverts and secondaries mostly white, also a few of the primaries ; legs and bill lighter than usual. There is no really-reliable evidence that the Fieldfare has ever yet bred in this country, though not a few more or less unsatisfactory instances have been from time to time recorded. For instance, Dr. Bree has recorded (29. June 12 and 18, 1869, & 34. 1864), what he regards as a " well-attested and proved case" of the Fieldfare nesting and rearing young in the grounds of the rectory at Alresford in 1869. The nest was built in the lower fork of the boughs of a medlar-tree on the lawn. The gardener was certain that the birds using the nest were not Mistle Thrushes, but further corroborative evidence is wanting. It was afterwards sent to Dr. Bree, and I have seen it in his collection, now in Mr. Harwood's possession. It is constructed exter- nally of birch and fir twigs, also of moss, coarse bents, and a few roots, lined with fine grass "and moss, which are the usual components of the nest of the Mistle Thrush." Blackbird : Turdus merula. An abundant resident. There are good reasons for believing that this species occasionally in- terbreeds with the Song Thrush in a state of nature. It varies greatly in number from time to time. Mr. Parsons records (35) an invasion of Blackbirds on New England Island, in October, 1836, almost every hedge being full of them for a week or two. White or pied varieties are rather fre- quent. The following curious circumstance blackbird, female, 1/4. is recorded in the Essex County Chron- icle for June 10th, 1887 :— " While two local constables [at Bradwell-on-Sea] were consulting for a few minutes the other morning, a blackbird settled on the helmet of one of them, where it remained some little time. It then flew on to a gate only a couple of yards off and sang splendidly for ten minutes without showing the slightest sign of fear." The following also appears in the same paper for May 1st, 1877 :— "There is a break-van at Mistley Station, which is used for the purpose of ' breaking down ' trucks to the quay, a distance of half-a-mile. This is used two or three times a day, and is frequently left on the quay two hours before being brought back to the siding in the yard. On the framework underneath the van, a Blackbird and his mate have built their nest, and the latter is now sitting upon four eggs, regardless of the frequent journeys to and fro." On April 24th, 1878, Mr. F. G. Marriage found a nest containing four fresh eggs at Springfield, built in the centre of a thousand-head cabbage.
