THE RED-BACKED SHRIKE. 



Lanius collurio (L.). 



The records o£ this species were ahnost all of first arrivals 

 and thus afford very little information as to its move- 

 ments. It seems probable^ however, that it arrived on the 

 south-eastern area of our coast-line, the earliest Shrike being 

 reported from Sussex on the 18th of April. Arrivals 

 apparently took place at intervals throughout May, and the 

 birds had spread as far west as Merioneth and as far north 

 as Leicestershire and Shropshire by the fourth week of the 

 month. 



Nests with eggs were found in Norfolk on the 26th of 

 May, in Somerset on the 27th and in Essex on the 30th.
