In April "Crested Larks" are entered, and a previous entry of the same is given on March 11th, both from XXVII. (Isle of May. [We would like to have examined these, and added the _real_ Crested Lark to the Isle of May Museum.] Not many records in April.
_In Autumn._--A few flying round the light on 24th August at N. Unst. Desultory movements at N. Unst in September.
In October about the 15th, 16th, 18th, an appearance of a "rush," or an actual "rush" on 18th at VIII. (N. Ronaldshay), and on 14th at XXVII. (Isle of May). At former 40 struck. E.S.E. wind. At latter "large numbers," with a S.W. gale, sleet. These no doubt are blown _off the land_. Latest date 18th. But reports in newspapers of immense gatherings of Larks near Dundee, St Andrews, and Midlothian and elsewhere, in January and again in March, being only, no doubt, local congregations caused by frost and snow in Scotland.
Sturninæ.--All returns for spring light. Earliest, February 9th at XXVII., and 11th at XIV. From 16th to 20th light returns, flock on 18th. By the 11th March breeding birds had arrived and taken up their haunts on XXVII., and about the same time an odd bird or two were seen resting on rocks of XXVI. (Bell Rock). Wind light westerly. As no records occur at Bell Rock at any other time in spring this year, even these odd birds occurring just at the time of arrivals elsewhere are significant perhaps of the general movement, these birds no doubt having overshot the land. Odd records in April at Fidra; a pair breeding there in May.
_In Autumn._--Earliest movement noticed at XXVII. "Large flocks of young birds, strangers." No records anywhere in September. In October movements noted at IV, (N. Unst) between 11th and 25th. On 11th flocks flying east, with light S.E. wind and haze. Only one record at XXVI. (Bell Rock) on 8th October. Rush decided at XXVII. on 17th, with strong E., rain and haze; two killed. Small movements at IV, VII, (Sumburgh Head), and XXVII. in November, and a few up to end of January 1886.
Corvidæ.--Earliest spring record of Rooks at XIV. (Pentland Skerries). Strong N.W. wind on 28th February. Rooks are recorded from the following stations:--VIII. (N. Ronaldshay), XIV, XXVII. (Isle of May); but all returns are very light indeed. In the first week in March a slight rush apparent at Sumburgh Head of Black and Hooded Crows--on 1st 50, on 6th 18, light N. to N.E.; and a few almost every day at XXVII. at same time. Records of Carrion and Hooded Crows are from VII. (Sumburgh Head), VIII., XIV., and XXVII. Earliest 1st March; latest 29th April. From three or four to eight or ten daily; long straggling migration.
