COLYMBUS HOLB(ELLI (Reinhardt). 

 HOLBCELL'S GREBE. 



iiABrrs. 



The extensive, deep-water marshes about the southern end of 

 Lake Winnipegosis, intersected by numerous sluggish streams ox- 

 dotted with man}^ small, shallow ponds, all of which are full of 

 fish or other forms of aquatic life, furnish ideal breeding grounds 

 for this and other water fowl. The banks of the Waterhen River, 

 which flows northward from Lake Winnipegosis into Waterhen 

 Lake, are broadly lined with man}^ miles of tall golden canes swarm- 

 ing Avith bird life of various kinds; countless yellow-beaded black- 

 birds are busy with their nesting in the densest canes or clinging to 

 the tops of the swaying stalks and pouring out their ceaseless chatter; 

 Franklin's gulls or black terns are flying overhead with gentle notes 

 of protest ; various species of ducks are swimming in the creeks and 

 pond holes; and the graceful western grebes glide in and out among 

 the canes where their nests are hidden. Here the shy Holboell's 

 grebe breeds in abundance, probably more abundantly than anywhere 

 else throughout its extensive range; though it is so seldom seen 

 that one does not realize how common it is until a systematic search 

 is made for nests. Waterhen River and the lake into which it flows 

 are said to have been so naiped on accolmt of the abundance there of 

 this species, although the name " waterhen," or " poule d'eau," is 

 applied to any of the grebes or coots.
