BIRDS OF GLOUCESTERSHIRE.

hills, generally foreboding stormy weather. A Glaucous Gull was shot 

 on the Severn some years ago. It is a large and beautiful bird, and is also 

 very rare. The last bird I have to mention is, perhaps, the rarest of all. 

 The Fork-tailed or Leach's Petrel is the only one of Mother Carey's 

 Chickens that has ever favoured our county. 



Colonel Montagu, in his History of British Birds, gives the total 

 number of species as 380, Morris 360, Yarrell 355. Of these at least 

 eighty are either extinct or so rare as scarcely to be considered 

 regular British birds, leaving a total of 280. Towards this number 

 I have been able to record 146 species, or rather more than half. 

 At first sight this may seem rather a small proportion, but when we 

 remember that nearly all of them have been seen within the last four years, 

 it is by no means a poor proportion. Again, there are numbers of the 

 various species of Geese, Ducks, Shore Birds and Gulls which I have no 

 doubt are found on the Severn, but which I have had no opportunity of 

 verifying. I shall endeavour to look them up at some future time. Fifty 

 of them are comparatively rare and nineteen very rare. 



Such then is our list of the " Birds of Gloucestershire," and though 

 our British birds are not so gaudy as those of warmer climes, yet they 

 are none the less beloved nor any the less interesting for being dressed in 

 sombre hues, which are, however, more harmoniously distributed, while 

 their songs are unrivalled throughout the world.
