8 REPORT ON THE MIGRATION OF BIRDS. 



late into April in Stirlingshire. A flock was seen among the foot- 

 hills of the Denny range by myself on April 16th. 



Saxicolin^. — In spring, Wheatears (** Stonechats must be 

 included here.* Another season Mr. Agnew will be able to 

 distinguish between true Stonechats and Wheatears, and I hope 

 other reporters also). Whinchats, Redstarts : First record 

 (Wheatear) at Isle of May, March 29th, strong W. wind, clear ; 

 latest (Eedstaiii) June 29th, light E., fog. But this may belong 

 to autumn ; next latest (Redstart) May 24th, at Isle of May. 

 Earliest Wheatear March 29th; latest, and a rush, on May 2nd 

 (along with other birds unknown), N.E., rain and fog, at Bell 

 Rock. A large bird struck heavily, and fell into the sea. Rush 

 of Wheatears, April 5th. Earliest Whinchat, March 29th ; 

 latest and rush, on April 15th, at Isle of May. Earliest Redstart, 

 April 2nd, at Isle of May ; latest June 29th, and next May 24th. 

 No great rush apparent. Of the above, Whinchats are also 

 named "Blue Janets," a name usually applied, however, to the 

 Hedgesparrow or Hedge Accentor. The record of June 29th, of 

 a Redstart in light E. wind, seems more of an accidental nature, 

 as it is separated from the one before by a month, and from the 

 true autumn migration by six weeks. Three sjoecies of Saxicolince 

 on East Coast in spring. In autumn, the same species. Records 

 from Whalsey, Sumburgh Head, Pentland Skerries, Bell Rock, 

 Isle of May, and Inch Keith. (Note. — These are the same stations 

 that reported last season.) Earliest Stonechat, and earliest record, 

 at Bell Rock on Aug. 9th, light S. breeze and fog ; latest Stonechat 

 Sept. 22nd, also at Bell Rock. Indications of a rush at Pentland 

 Skerries on Sept. 3rd. ''Blue Janets" participated in the 

 October rush already spoken of (see under Turdid.e). Earliest 

 Wheatear, Aug. 17th, at Pentland Skerries ; latest Sept. 17th. 

 Earliest Redstart Sept. 15th ; latest Oct. 22nd. No additional 

 species of Saxicolince appeared'in autumn. 



SiLViiN^. — In spring, Robins at Bell Rock only ; one seen on 

 April 10th, struck lantern, but not killed. But "unusual num- 

 bers" were seen at Isle of May in April, and in spring generally. 

 In autumn, Robins at Sumburgh Head (where they are very 

 rarely seen), N. Ronaldshay, Pentland Skerries, Dunnet Head, 

 Chanonry, Bell Rock, Isle of May, and Inch Keith. Earliest at 



* In so far as the records apply at Isle of May.
