THE TREE-PIPIT. 



Antlms trivialis (L.)* 



The first immigration of this species took place on the Kent 

 :ind Sussex coasts between the 11th and 13th of April. This 

 ^vas followed by further arrivals on the 15th and 16th, and 

 by the 17th some individuals had reached Worcestershire, 

 Staffordshire, Lincoln and Northamptonshire. Between the 

 18th and 21st Tree-Pipits were steadily arriving in the south- 

 east and slowly extending their range throughout the country ; 

 the first records from Wales and Derbyshire being on the 20th 

 and 21st, from Cumberland on the 25th, from Westmoreland 

 on the 28th, and from the Clyde area on the let of May. 

 A fresh arrival was noted in Sussex on the 27th, and on the 

 same day an increase in numbers was noted in Leicester- 

 shire, Shropshire and Cheshire. Further arrivals reached 

 Kent and Hampshire on the 4th and 5th of May, and these 

 evidently contributed to the marked increase recorded in 

 the west and north during the following five or six days. 

 On the lOth/llth some were taken at the Kentish Knock 

 light-vessel, and an increase was noted in Lincolnshire, York- 

 shire and Northumberland during the three following days. 

 Between the 15th and 1.9th a further increase was noted in 

 several of the western counties, which possibly points to an 

 unrecorded immigration having reached our shores about the 

 first-named day. The earliest nesting record was of a pair 

 building in Radnor on the 15th, and after the 20th nesting 

 became general.
