fifth is the thnla (ardea thula) a name derived from 

 the Chilian ; it is entirely white, and its head is 

 adorned with a beautiful crest of the same colour. 



Of the two kinds of ea,^lcs in Chili, one is the yel- 

 low eagle of Europe, called by the Indians gnanca, 

 and another species called calquin, which appears to

The turtle-doves are of two species ; the one is

There are four species of the woodpecker ; the 

 green, the Virginian, the carpenter, and the pitiu. 

 The carpenter (picus lignarius) is less than a star- 

 ling, and has a rèd crest, and the body is variegated 

 with white and blue. The bill is so strong that it 

 perforates with it not only dry but green trees, and 

 proves very injurious to the fruit trees, by making 

 deep holes in them, wherein it deposits its eggs.

 Its plumage is brown, spotted with white, and its 

 flesh is held in much estimation. This bird lays four 

 eggs, but it does not, like others of its species, nest 

 in the holes of trees, but in excavations which it
