COLYMBUS HOLBCELLI (Reinhardt). 
HOLBGLL’S GREBE, 
HABITS. 
The extensive, deep-water marshes about the southern end of 
Lake Winnipegosis, intersected by numerous sluggish streams or 
dotted with many 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 many miles of tall golden canes swarm- 
ing with 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 named on account of the abundance there of 
this species, although the name “ waterhen,” or “poule d’eau,” is 
applied to any of the grebes or coots.
