SOME RARE AND INTERESTING MIGRATORY BIRDS 7 



previous records for passage movements at the Orkneys are few 

 in number. 



White Wagtail {Motacilla alba). Seen at intervals on passage 

 from the day of our arrival, 3rd September, down to the 2nd 

 October. On one occasion only did it appear in numbers, namely, 

 on 6th September, when a lot arrived overnight, and about forty 

 were seen, on the wing simultaneously. Hitherto, from want of 

 systematic investigation, this common migrant at our northern 

 stations has only been rarely recorded from Orkney. 



Red-throated Pipit {Anthus cervinus). A young male was 

 obtained on 1st October a welcome addition to the few authentic 

 British records of the occurrence of this native of the high northern 

 regions of the Old World. It is an addition to the fauna of the 

 Orcades. 



Tree-pipit {Anthus trivialis). On several days from the 

 15th to 22 nd of September this bird was quite abundant on 

 passage. Hitherto there have been very few records of the 

 occurrence of the Tree-pipit at the islands of the Orkney group. 



Red-breasted Flycatcher {Muscicapa parva). A young male 

 frequented the face of the cliffs on 21st and 22nd September. This 

 is the second record of the visit of this species to the Orkneys ; 

 the first occurrence was at the Pentland Skerries on 30th September 

 1912. 



Barred Warbler {Sylvia nisoria). On the 6th of September 

 an adult was found amid some nettles. There is only one 

 previously known visit to the Orkneys of this now not uncommon 

 autumn visitor to our isles, namely, at this same island on 15th 

 August 1912. 



Lesser Whitethroat {Sylvia curruca). Three single birds 

 appeared in the garden, or on the face of the cliffs, on 4th, 24th, 

 and 28th September. Hitherto this species has only been known 

 to visit Sule Skerry and the Pentland Skerries ; once at the former 

 and in fair numbers at the latter in 19 12. 



Dusky Willow- warbler {Phylloscopus fuscatus). In the 

 December number of this magazine, p. 271, the date for the 

 occurrence of this new British bird was unfortunately given as 

 3rd October, it should have been the 1st of that month. 



Yellow-browed Warbler {Phylloscopus superciliosus). The 

 first known visit of this native of Siberia to the Orkney Islands 

 occurred on 29th September, when one was found in a patch of 

 nettles one of the very few spots affording shelter in the island. 



Wood-warhler {Phylloscopus sibilatrix). One was observed 

 in the cover afforded by the nettles on the 30th of September. If
