 fifreen — may occasionally l)e seen. P^ven on the most frequented lakes 

 numerous broods of golden-eye ducks may be found, and on the 

 less frequented lakes the rare harlecjuin may Sometimes be seen al- 

 though it prefers rapid riA^ers and streams to the quieter waters. On 

 lakes where safe secluded nesting sites are to be had the Canada goose 

 may perhaps be discovered. Along the lake shores the spotted sand- 

 piper, Cirinnell water-thrush, and now and then the kingfisher and 

 water ouzel may be noted, although both kingfisher and ouzel are

 white-throated — or a hummingbird — generally the rufous but possi- 

 bly the calliope, black-chinned or broad-tailed — may be caught sight 

 of in passing. 



Inside the forest three species of grouse — the Richardson, Frank- 

 lin, and ruffed — may be flushed, while the close investigator or the 

 camper may be fortunate enough to discover some of the resident 

 owls, including the MacFarlane screech owl, the western and dusky 

 horned owls, the rare hawk owl, and the Rocky Mountain pygmy. 

 A number of woodpeckers are also to be closely watched for, among 

 them the Rocky Mountain hairy, Arctic three-toed, Alaska three-toed,
