wind and weather, for the rest of the season. February was a most unusually mild month, many days being equal in temperature to what we expect at the end of May. This spring-like weather had the effect of inducing an earlier migration of the more hardy species. The same phenomena were observable, although to a less extent, on our own shores, and I noticed that the immense flocks of Golden and Green Plover frequenting our Lincolnshire marshes broke up and took their departure some time in advance of the average period.
Mr. Gätke's notes commence with the end of January, and are continued as follows:—
"January, night, from 27th to 28th. Turdus pilaris, countless flights.
