Dr. A. Ti. Thomson : Txesvlfs of a Stvdi/ of [Ibif 



distance from those at which the birds were marked, and 

 there are only a very few from more distant parts of Great 

 Britain. The birds would therefore appear to be either 

 definitely sedentary or definitely migratory, in ihe latter 

 case performing comparatively quick journeys rather than 

 gradual movements. 



The number of Irish records justifies a sup])]omentary 

 analysis of tliese in more detail, and this is provided in 

 Table V. 



TABLE Y. 



Seasonal Analysis op Reappearances in Ireland op 



Lapwings marked as chicks in Scotland or 



THE north op England. 



From this table it is evident that the records are evenly 

 distributed amouL!,' the tliree southern provinces, but are few 

 in number in Ulster. The only Ulster records, and the 

 majority of those from Leinster, refer to the first half of 

 the winter season, while most of the records from the other 

 two provinces occur in the second half : this might be 

 explained either by a local south-westerly movement during 

 the winter or by longer jouineys on the part of later arrivals 

 from Great Britain, but the numbers, when thus subdivided, 

 are rather small to be accepted as significant. 



The following table analyses the same records as were 

 dealt with in Table IV., but does so in accordance with the 

 ages of the birds at the time of reappearance : —
