364 THE BIRDS OF THE BRITISH ISLES. 



Siberian Thrush, Turdus sibirlcns Pallas. Two recorded, but 

 rejected by Saunders on account of insufficient evidence. This 

 bird has been met with elsewhere in Europe and is as likely to 

 wander as many other birds on the British list. 



American Robin, Turdiis migratorms Linn. Four or five 

 records, two of them for Ireland. Mr. Harting thinks that it 

 should be included, as it has been recorded from Heligo- 

 land and elsewhere in Europe. It has been released in 

 England. 



Blue Rock-Thrush, Moniicola cyajius (Linn.). , Recorded in 

 error. 



Siberian Ruby-throat, Calliope calliope (Pallas). Recorded 

 as seen at Westgatc-on-Sea, 1900. 



?iIocking-Bird, Mimiis polyglottus (Linn.). Almost certainly 

 all the occurrences have been of escaped cage-birds. 



Dusky Bulbul, Pycnonotus barbatus (Desfont.). Hastings, 

 i860. Record discredited. 



Cape Bulbul, PycnonotHS capensis (Linn.). Waterford, 1838. 

 An even more doubtful record. 



Chestnut-bellied Swallow, Hinnido savigiiii Stephens. An 

 error. 



Tree-Swallow, Iridoprocne bicolor (Vieil.). Derby, 1850. 

 Wolley believed this record to be genuine ; it was shot from 

 amongst Sand-Martins and is preserved at Norwich. It is an 

 unlikely cage-bird. 



Purple Martin, Progiie snbis (Linn.). Dublin, 1840 ; Hudders- 

 field, 1854. Others have been reported and proved incorrect, 

 and Nelson was doubtful about the Yorkshire record. 



FHcker, Colaptes aiiratus (Linn.). Wiltshire, 1836. 



Downy Woodpecker, Dryobales pubescens (Linn.). Dorset, 

 1836. 



Hairy Woodpecker, Dryobates villosus (Linn.). Four records. 

 The occurrence of these three American Woodpeckers is 

 most unlikely ; about this date there was a goad deal of trading
