Migration, 

 summary of movements. 



January, 



With the exception of Swans there is no record of move- 

 ment up to 2 1 St January, this period being characterised by 

 unsettled weather and varying winds. At 2 A.M. on the 

 22nd a rush of Skylarks is reported from Little Ross lantern, 

 and that night Lapwings, Thrushes, and Skylarks from the 

 same place ; and these species, with the addition of Golden 

 Plover and Curlew, at the Pladda lantern. From this date to 

 the end of the month nothing worthy of note occurred, with 

 the exception of thousands of Little Auks in Yell Sound 

 (Shetland) on the 29th. 



February. 



A weather movement caused by frost was evident in 

 the first week of February ; records of this come almost 

 exclusively from north of the Tay. In the second week, 

 though cold weather continued, we have notes of some of 

 our partial migrants returning to their inland nesting places. 

 The second half of the month showed a strengthening of this 

 movement, and in addition we find winter visitors making 

 their way northwards and a good deal of movement among 

 Duck and Geese. It would appear that both weather and 

 migration were perfectly normal throughout the month. 



March. 

 With unsettled weather throughout the month but little 

 migration is recorded in March ; the movements showed a 

 continuation of those noted in the second half of February. 

 One or two Lesser Black-backed Gulls arrived, and the first 

 Wheatear was seen on the 30th. 



April. 

 More migration was evident in April ; in the first half 

 this was chiefly of the same nature as that of the preceding 

 month, with the addition of a larger arrival of summer 

 visitors and a little passage migration. In the second half 

 there was a very big arrival of summer visitors, which seems 

 to have been little, if at all, interrupted by a heavy fall of 

 snow on the 27th, In addition to this, passage migration
