THE BIRDS OF FAIR ISI.E 125 



Durino- these movements the bird is not uncommon, 

 and both sexes were particularly abundant from the 12th 

 to the 23rd of May 19 10, arrivino- concurrently. 



In autumn young birds only have hitherto been 

 detected, and the bird has always been somewhat scarce 

 at this season. The passages have been confined to
