THE BLACK-XECKED .-SWAK.* 



A very beautiful species of the swau is found in Chili, the Falkland Islands, the River 

 Plate, and other parts of South America. It is distinguislied by a black neck, which 

 finely contrasts with the snowy whiteness of the rest of its plumage. The bill is red, and 

 the legs flesh-colour. The engraving exhibits two of them lately bequeathed by the 

 Earl of Derby, from his celebrated collection at Knowsley, to the Zoological Society of 

 London, of which his lordship was the president. The society now possesses four 

 examples of the black-necked swan. One other pair only exist in Europe, and are in her 

 Majesty's collection at Buckingham Palace. 



The comparison, " like to a black swan," arose from its being supposed there was no 

 such bird ; but the Anas Phdonia of Shaw has now become common in our menageries, 

 where it breeds freely. It is black, with the exception of the primary and a few of the 

 secondary quills, which are white. The bill is bright-red above, and sometimes has a 

 slight tubercle at the base, which the female wants. The anterior part of the upper 

 mandible is crossed by a whitish band. 



THE HOOPER, f 



The Hooper, or '\^Tiistliug Swan, is a winter visitor to the British islands, even to the 

 southern parts, arriving in flocks, sometimes as late as Christmas, and they are generally 

 more numerous as the weather becomes more severe. The Rev. Mr. Low says : — " The 

 wild swan is found in all seasons in Orkney ; a few pairs build in the holms of the loch 

 of Stenness. These, however, are nothing to the flocks that visit us in October from the 



Cygims NigricoUis.
