RuTiciLLA PiicKNicuRUS, Rcdstart. — The Redstart is 

 a regular and common visitor in both spring and 

 autumn. 



The earliest dates for its advent in spring are 22nd 

 March 1909, and the 4th and 9th April, when single

 1 8th, 2ist, and 23rd; but it is not until 12th May that 

 it has appeared in numbers, and the passage usually 

 lasts until the end of the third week of the month. In 

 some seasons a few have been observed as late as 

 the end of the first week of June, and a single bird was 

 seen on 13th June in 19 10. 



According to the records, the males arrive first in 

 spring, being from six to seventeen days in advance 

 of the females. Later both sexes appear simultaneously 

 on passage. 



The return movements usually commence in Sep-

 the first migrant was seen on 29th August. The main 

 flights occur towards the end of September, but small 

 numbers appear during October, and there is one record
