The winter of 1881-82 has been remarkable for its high temperature, no such uniformly mild season having occurred for many years in England. The same has been the case over the whole of Northern Europe north of latitude 50° N. As might be expected, so exceptional a season has not been without its effect upon our immigrants. Fieldfares have crossed in very limited numbers, and have everywhere been remarkably scarce in localities along our east coast. Large numbers of birds which regularly arrive in the autumn, as the Greenfinch, Chaffinch, Tree Sparrow, Snow Bunting, and others, and which remain for a few days only and then pass on, have this winter continued for many weeks, and even months, resorting in immense flocks to the stubble-fields near the coast, where, with no severe weather to drive them away, they found an inexhaustible supply of food in the large quantity of grain dashed out in harvest-time by the great gale from S.W. to W. on August 26th. Snow Buntings have been considerably in excess of anything known for many years, the proportion of old birds not more than one in a hundred. Another consequence of the mildness of the winter is the desultory fashion in which birds have migrated; there have been less of those great "rushes," when for days together one species after another rush helter-skelter on to our coast. Migration has also been greatly prolonged, and the latest returns received show Rooks, Starlings, and Larks still crossing the North Sea in February. The last week in August and first in September Wheatears and Redstarts passed as usual up the coast from N. to S., the line of migration being confined to the chain of sandhills. Also during the first week of September, and again about the 20th, there was an immense migration of the _Sylviinæ_ in the same direction. Migration appears to have reached its climax on or about Sept. 22nd, an enormous number of various immigrants coming in from this time to the end of the month. Not the least remarkable was the influx of the larger raptorial birds crossing Heligoland on Sept. 22nd and two following days, and were about the same period seen along the entire range of our eastern coast. From this date to the end of October ten Ospreys were procured from localities contiguous to the east coast of England, between the Tyne and the Thames. Again, the third week of October there was another large immigration of birds of various species. On the night of Oct. 24th great numbers of Mealy Redpoles came in on the Holderness coast; the same flight was also traceable as far north as the Farne Islands; the Mealy Redpoles appear to have been accompanied or closely followed by a flight of Siskins. Hooded Crows came with their usual regularity, almost to a day; this autumn the great flight crossed Heligoland on the afternoon of Oct. 17th, and on the 18th. There was a corresponding arrival along the whole of our east coast on the night of 17th or early morning of 18th, and on the 19th.
