Great Britain; amongst them the Bass Rock, Ailsa Craig, and 
Lundy Island may be mentioned *. 
The Gannet, like the Cormorant, has a slightly distensible 
naked portion of skin at the top of the throat in front, extending 
to the underside of the bill. This is greatly exaggerated in a 
Bird which is entirely strange to our own climes, though a 
common inhabitant of our Zoological Gardens. We refer to 

The Common Gannet (Sula bassana). 
the Pelican (Pelecanus onocrotalus), the unwieldy form and 
awkward gait of which, as well as its long bill with the great 
bag of skin beneath it and in front of the throat, must have 
strongly impressed every one who has seen it. Unwieldy 
as it is, and very web-footed, it is fond of perching on trees. 
It inhabits Africa and the Western and Central parts of Asia 
* Thousands breed at St. Kilda.
