intervals in September and clurinc^ the first half of 



October. 



The Swallows which arrived in numbers on 19th 



May 1 9 10 seemed to be tired out, for they frequently 



settled on the erass close to the observers, and also on

the rocks at the foot of the cliffs. 



HiRUNDO RUFULA, Red-rumped Swallow. — On the 

 2nd of June 1906, the isle was the scene of the arrival of 

 a great number of migrants rushing northwards. These 

 included Bramblings, Tree-Pipits, Spotted Flycatchers, 

 Red-backed Shrikes, Swallows, Cuckoos, Dunlins, and

A single bird of this species was obtained at Heligo- 

 land on 30th May 1885, and one has since occurred on the 

 south coast of Kont, namely, on the i6th May 1909.

The earliest date for its spring appearance is 7th 

 May, and the average date 15th May. It often occurs 

 in considerable numbers late in May and during the first 

 week of June, and a few are observed down to near the 

 close of the latter month. During their short sojourn
