Grebe Group 



A grebe swhns in stately fashion, while, 

 ing frorn the warm cradle of her back, eager 

 tented young birds take a sail with her 



even before the ice is melted. To 

 secure the young birds for this group 

 it was necessary to hatch the eggs of 

 the wild goose under a hen, so difficult 

 is it to find the young in nature.

 Crane Lake, Saskatchewan, Canada.) 

 The grebe is another of our aquatic 

 birds which builds its 

 nest near the water. 

 During the incubation period the par- 

 ent bird usually covers the eggs with 

 grass and reeds when leaving the nest. 

 Nesting at the same lake with the 

 grebe was the red-head duck, which 

 lays from fifteen to twenty eggs.

 The loon is justly famed for its 

 skill as a diver, and can 

 swim with great speed 

 under water. Its weird call is a

I he group represents a 



typical scene during the Group 



mating season. The 

 male birds go through most surprising 

 antics in their efforts to attract the 

 females. They inflate the orange- 

 colored sacs on the sides of their 

 necks, dancing and strutting about 

 and uttering a loud resonant booming 

 note. (Reproduced from studies near
