THE BIRDS OF DEVONSHIRE. 157 



Montagu obtained an immature bird as late as 

 the beginning of November. Dr. Elliot writes 

 that, a Black Tern was killed near Kingsbridge, in 

 May of the present year, (1890), adding that 

 vernal occurrences in his neighbourhood are rather 

 unusual. 



WHITE-WINGED BLACK TERN.— 



Hydrochelidon leucoptera (Schinz). 



A RARE visitant. "A specimen," writes Mr. 

 Howard Saunders, "in a very interesting state of 

 change from summer to winter plumage is in the 

 possession of Mr. Westlake of Ilfracombe, North 

 Devon, shot there early in November, 1870" 

 (Yarrell. B.B. III. p. 523). The late Mr. Ross 

 appears to have recorded this species as once 

 captured at Plymouth, but as Mr. Rowe excludes 

 this species from his list of 1863, it seems undesirable 

 to repeat a record which may possibly have already 

 been proved to be erroneous. 



WHISKERED 'YY:KS.—HijdrorheUdon hybrida (Pall). 



A RARE visitant. In May, 1865, a single example of 

 the "Whiskered Tern was captured by some fisher- 

 men near Plymouth, a bird in full breeding 

 plumage. It was purchased by Mr. Gatcombe, 

 from whom it passed into the possession of Mr. 

 Howard Saunders (Yarrell. B.B. III. p. 528).
