As already mentioned in our General Remarks on 1882 Report (Fourth Report, 1882, p. 67) the effects of these gales and N.E. winds in spring of 1883 was almost to stop migration at Isle of May, which migration had "set in pretty briskly" on March 2nd, and almost ceased on the 5th. From the latter date only a few "stragglers of the strongest wings" up to the 19th; while a great concourse of Wagtails was observed inland in Edinburgh (see report as above quoted); few were seen at Isle of May till the 30th, when five came with S. gale (_op. cit._, p. 68). The general migration was much weaker in numbers this season in spring, and this is doubtless owing to the prevalence of strong S.E. gales and winds at the time of migration, moderate S.E. or easterly winds being preferred. Still there were considerable rushes at the more favourable localities for observation especially of Thrushes and other _Turdidæ_. The anomalous migration recorded by Mr. Cordeaux on to part of the English coast between Feb. 18th and May 18th,[29] with strong E. and S.E. winds, changing occasionally by N.E. to W. and N.W., is somewhat difficult of explanation, unless we could correlate data from the opposite coasts at the same dates in spring of 1883; but the fact stated by me that migration began briskly at Isle of May on March 2nd and almost ceased by the 5th may indicate that the migration thus retarded by adverse winds, or altered in direction thereby, passed N. by more inland routes, avoiding the Scottish coast-line, and hugging every sheltering hollow of land. Blown across the North Sea at the more southerly stations, they then crept northwards silently and more inland. Being all adult birds, and having crossed the North Sea not at the widest part if they came with a S.E. wind, less exhaustion would occur, and thus, passing inland, they would escape notice near the coast. [Footnote 29: See p. 60 of this Report.] Before we can speak with much certainty as to the progress of spring migrations into the further districts influenced by them, we require more full and continuous data from Faroe and Iceland. Still, the earliest appearance noted in Iceland of the Redwing, _Turdus iliacus_, on April 7th, 1882, should be noted as a possible means of comparison in that year with the returns from our own coasts. Data from our West Coast of Scotland help us little in 1883 in spring, and even less so in 1882, as regards _Turdidæ_. Wheatears again, in 1882, are noted not before April 24th, and on West Coast of Scotland the migration, though but scantily observed, began on March 9th and terminated as late as May 17th (see 1882 Report, p. 57).
