XLIX. 

 THE AZURE CROWN HUMMING-BIRD. 



'N the tropical regions of Brazil, the birds 

 have no need to migrate, from one part 

 of the country to another, to escape the 

 winter. There is no cold season to drive 

 them from their haunts and homes. So that the 

 Cuckoo never flits, as she does in England, and 

 the Swallow is seen making his aerial curves and 

 sweeps the whole year round. 



But many reasons impel the birds at times to 

 wander. 



At one season of the year, great rains fall and 

 deluge the ground. Then, the forest becomes too 

 damp and cool to be pleasant to the birds.
