The observations made upon the Tree Pipit, twenty-one in number, call for no particular comment, save that the direction of the wind at several dates of supposed arrival was from a S.W. or S.E. quarter, corresponding with what has been observed of other migratory birds, and tending to show that they prefer to travel with a side wind rather than with a head wind or the reverse. In the eastern counties, for example, it was observed that the Tree Pipit arrived in Norfolk with a S.S.E. wind, the temperature being 52°; in Lincolnshire with a wind veering from S. to S.E. and E., the weather dry, cold, and cloudy; in Yorkshire with a S.W. wind, weather fine, and temperature 47·5°. It was first observed at Bushey, in Hertfordshire, as if arriving directly from the eastward, on the 8th of April; and was last heard at Ratham, near the coast of Sussex, on Sept. 15. The furthest point north at which it was noted was near Stirling on May 1. In Ireland it is unknown. In the case of the Sedge Warbler, we again remark observations on the wind at the presumed dates of arrival in all respects confirmatory of what has been already stated. Four good observers in the counties of Norfolk, Lincoln, Derby, and York noted the direction of the wind when first meeting with this bird as S.S.E., S.W., S.E., and S.S.W., respectively. No record of its occurrence in 1872 either in Scotland or Ireland was received. The general period of its arrival in England seems to be during the last fortnight of April. About the same period arrives the Yellow Wagtail, or Ray’s Wagtail, as it is called by many, respecting which bird sixteen observations were received from different parts of the country. It does not appear to have been met with further north than Wakefield, and no notice was taken of it by correspondents in Scotland and Ireland. The Wryneck, or Cuckoo’s-mate, long preceded the Cuckoo in the date of its arrival, having been heard at Reigate as early as March 31, and at Ratham, in Sussex, on April 2. On the 6th and 7th of the latter month it was observed at several localities in Norfolk, and its appearance generally throughout England in 1872 seems to have been noted during the first fortnight of April. Mr. Lister states that, although found in the neighbourhood of Barnsley in previous years, it was not observed there in 1872. The Nightjar seems to have been generally met with throughout the country as far west as Llandderfel, in Merionethshire, and as far north as Garvoch, in Perthshire. Mr. Gatcombe observed it in the neighbourhood of Plymouth on April 10, but this must be regarded as an exceptionally early date, for the majority of my correspondents did not meet with it until quite the end of April and beginning of May. On the 15th of June Mr. P. Henderson found two young Nightjars on Tents Muir, Fife, _amidst a colony of terns_ (!), and kept them alive for some time on moths, worms, and pieces of raw meat.
