LARIDA, 637 
THE WHISKERED TERN. 
HyYDROCHELIDON HYBRIDA (Pallas). 
The Whiskered Tern has even a less northward range than the 
preceding species, and only wanders to our islands at long intervals. 
It was first recognized by Heysham, who selected the subject of the 
above illustration from some sea-birds which had been shot at Lyme 
in Dorsetshire towards the end of August 1836; in September 1839 
one (in the Warren collection at the Dublin Museum) was obtained 
at the mouth of the Liffey; a third was killed, according to Mr. 
Southwell, near Hornby Castle, Yorkshire, in 1842 ; an adult female 
containing advanced ova was shot on Hickling Broad, Norfolk, on June 
17th 1847, and one was obtained at Dersingham in October 1890 ; 
an immature example was procured at the end of August 1851, near 
Tresco, in the Scilly Islands; an exhausted adult picked up on the 
water near Plymouth in May 1865 and presented to me by the late 
Mr. Gatcombe, is now in the British Museum; and Mr. Hart, of 
Christchurch, Hants, has an adult killed in June 1875. An old male, 
shot in Nithsdale, on May 28th 1894, is in the Edinburgh Museum. 
This Tern is a very rare straggler to Northern Germany, and 
seldom wanders up the valley of the Rhone, though it used to nest 
Sparingly in the delta of that river. Large numbers arrive by the 
middle of April to breed in the marshes of the south-west of Spain ;
