178 Mr. J. Cordeaux on the Heligoland 



tion. I also observed many examples in the bird-stuffers' 

 shops. It occurs every May, if warm and moist, in gi'eat num- 

 bers, twenty to thirty, and even forty a day ; but with cold and 

 dry weather, and northerly winds, it is very scarce. It again ar- 

 rives, when fine, at the end of August, and in greater numbers 

 than in the spring ; it is then found in the potato-plots on 

 the exposed and open part of the island. In the spring it 

 is to be met with in the gardens, in gooseberry-bushes, &c. 



RuTiciLLA PHCENicuRus (LinnsBus) . 



A common migrant. About ten days before my visit, 

 namely on the night of the 3rd of September, 1874, many 

 Redstarts and Stonechats were taken round the lighthouse. 

 Like almost every bird captured on the island, they were 

 plucked and eaten. From the number of wings and tail-fea- 

 thers of these species scattered about, their number must have 

 been very considerable. One in the collection, with large 

 white patch on the secondary wing-feathers is perhaps Sylvia 

 mesoleuca, Ehr. See Ibis, 1874, p. 343. 



RUTICILLA TITYS (Scopoli) . 



A not uncommon migrant. I saw either a female or young 

 bird of the year on the cliff on the morning of the 14th. 



Saxicola rubicola (Linnseus). 



A common migrant in the autumn, arriving early in Sep- 

 tember. 



Saxicola rubetra (Linnaeus). 



The same remark applies ; but this is always the most plen- 

 tiful of the two. 



Saxicola (ENANTHE (Linnseus). 



Very numerous both in the spring and autumn. I found 

 it plentiful on the Heligoland cliffs, as well as on Sandy 

 Island. In the afternoon of the 19th of September, when 

 beating out of the North Channel, several Wheatears, coming 

 from the N.E., passed the cutter, flying just high enough to 

 clear the waves, and making for the island.
