THE HUMMING-BIRDS OF THE FOREST. 195 



tanned leather, and has a kind of ridge or rim 

 round the top. 



This rim is to prevent the eggs from rolling out. 



The range of the Humming-Birds, like that of 

 the Parrots, is wider than was once imagined. 



The tropical region is their natural home ; and 

 every attempt to rear them in our colder climate 

 has been in vain. 



But they have been known to wander far 

 beyond the limits of the Torrid Zone. They pay 

 flying visits to Canada, and even travel as far as 

 the land of the Seal and the Penguin. In the 

 Southern Hemisphere, Humming- Birds have been 

 seen in Patagonia. But this seems to have been a 

 mere summer excursion, for they retreated before 

 the first breath of autumn.
