THE TREE-PIPIT. 



Antlms trivialis (L.). 



The records of this species indicate that it arrived at first 

 in a straggling manner, a few birds at a time, during the 

 first three weeks of April, at different points along the south 

 coast from Kent to Cornwall. The birds spread fairly rapidly 

 in a northerly direction and distributed themselves all over 

 the country. 



An immigration of rather larger numbers occurred along 

 the whole of the south coast on April the 21st and 22nd> 

 and supplied the places in the southern counties o£ those 

 birds that had passed on. 



During the last four days of April and on the 1st of May 

 a larger number of immigrants arrived along the whole 

 south coast, but mainly to the east of Hampshire, and this 

 immigration may perhaps be regarded as the main body of 

 our resident Tree-Pipits. After their arrival the numbers 

 recorded all over the country show a marked increase, and, 

 with the exception of the changes caused by the earlier 

 arrivals passing on north and the later ones taking their 

 places, little further change was noted. 



There seems to have been some slight evidence of further 

 arrivals of this species in Dorset on May 12th and 17th and 

 in Sussex on the 15th, but it was not strong enough to be noted 

 as a fact. At this time our resident birds were already 

 nesting and eggs had been recorded from Cambridge on 

 the 21st and from Derby on the 28th.
