This is another exceptionally rare visitor to Heligoland. Rey- 

 mers possessed a fine old male fifty years ago ; another was shot 

 on the 8th of November 1847 ; to this was added a companion 

 female, which was shot by Oelrich Aeuckens on the 5th of April 

 1849 the day of the memorable fight of Eckernforde. Besides 

 this, the bird has up to the present time been seen on about three 

 or four other occasions, without, however, having been shot. 



In the case of this beautful little bird, its rare occurrence in 

 Heligoland need not create surprise ; for its breeding range does not 

 advance to such high latitudes as that of any of the preceding species, 

 but terminates in northern Germany. So that, according to Pro- 

 fessor Newton ( Yarrell's British Birds), the individuals which have 

 been observed in Heligoland must be regarded as having advanced 

 to the most northern limit of their range. The nesting stations of 

 this species extend through the whole of central and southern 

 Europe as far as Asia.
