248 THE HISTORY OF ANIMALS. [B. IX. 



is similar to the black cottyphus, but is rather smaller. It 

 makes its house upon rocks and tiles. It has not a dark 

 beak, like the blackbird. 



2. Of thrushes there are three forms. The one is called 

 misselthrush, for it lives upon nothing but miseltoe and resin. 

 It is as large as the citta ; the other is called fieldfare. The 

 voice of this bird is shrill ; its size is that of the blackbird. 

 There is another kind, which some persons call illas, which 

 is smaller than the others and less variegated. 



3. There is a certain bird living on rocks, which is called 

 blue thrush. This bird generally inhabits Scyrus. It lives 

 upon the wing. It is less than the blackbird, but larger than 

 the finch. Its feet are black, and it climbs up upon rocks. 

 It is entirely blue. It has a smooth, long beak, but its legs 

 are short, and resemble those of the woodpecker. 



CHAPTER XIX. 



1. THE oriole is entirely of a yellowish green. This bird 

 is not visible in the winter. It is seen in the greatest num- 

 bers at the summer solstice, and takes its departure when 

 Arcturus rises. It is of the same size as the turtle. The 

 malacocraneus always perches upon the same place, and is 

 captured there. This is its appearance : its head is large, 

 and has the form of cartilage ; its size is smaller than the 

 thrush ; its beak is strong, small, and round ; its colour is 

 entirely cinereous ; its feet are strong, and its wings weak ; 

 it is generally captured by the owl. 



2. There is another bird, called the pardalus, which is 

 generally gregarious, and a single bird is never seen. Its 

 colour is entirely cinereous. In size it resembles those 

 already mentioned. Its feet are strong, and its wings are 

 not weak. Its voice is frequent and not deep. The colly- 

 rion lives on the same food as the blackbird, and in size 

 much resembles those just named. It is generally taken in 

 the winter. These birds are visible all the year round, and 

 so are those which live in the neighbourhood of towns, the 

 raven and crow ; for these are always visible, and neither 

 migrate nor conceal themselves. 



3. Of the jackdaw there are three kinds, one called cora- 

 cias, which is as large as the crow, and has a red beak ; 

 another is called lycius ; there is also a small one called
