near the entrance to the cafions, and also the sedge and tulc marshes, in 

 the neighborhood of the lakes and rivers. The birds most charactenstic of 

 the meadows are all mostly peculiar to them, being seldom if ever found in 

 other localities. Besides the land-birds here enumerated, a multitude of the 

 water-fowl resort to the meadows during the breeding-season, but these are 

 best given in a separate list. The most characteristic birds of the meadows 

 are the following: — 



1. Telmatodytes paludicola Marslies. 



li. Coturniculus pcrpallulus Dry meadoics. 



3. Passereuhis alaudiuus Wet meadoics. 



4. Agehi'us phceuiceus Marshes. 



5. Xantliocepbalus icteroccphalus.. 3/ar«/ics. 



6. Sturuella neglecta Evcryichere except in marshes. 



7. Pedioecetes columbianus Dry meadows. 



8. Grus canadensis Wet meadoics. 



9-11. Mural Avifauna. — This group is a rather heterogeneous one, 

 part of the species being saxicoline, while others nest in vertical banks of 

 earth; and of the former only two species keep altogether among the rocks, 

 the others merely breeding there, the greater part of their time being spent 

 in obtaining their food in other localities. 



They may be gi'ouped as follows: — 



a. Species strictly saxicoline.
