54 PONDS, PADDOCKS, AND AVIARIES 



worthy of notice as exceedingly rare in living collections, 

 though common enough in Andalucia and North-west 

 Africa. Perhaps the most beautiful of the web-footed 

 birds in this portion of our aviaries are the Japanese 

 teals ; but with these little ducks, as indeed with almost 

 all others of the duck, family, we have been grievously 

 disappointed in our hopes of nests and eggs ; in fact, 

 in the case of the two last-mentioned species, I am not

 North America, and of the white snow-goose from the
