 Hab. Europe. 



The Garganey is always to be found represented in the Collection, 

 being recorded in the earliest list (1831), the Catalogue of 1849, and 

 the various Lists of Animals (1852-79). It is, however, I consider 

 rather a shy breeder, having only bred twice with us, so far as I can 

 ascertain by our records.
