 their eastern limit in the first-named locality, (exami)les are. 

 Western (Jrebe, Franklin's (hill, (California Gull, White Pel- 

 ican, Wilson's i^lialarope. Long-billed Curlew) ; second, by 

 the presence of plains or alkaline lake species, not observed 

 about Shoal Lake, (examples are, Avocet, Western Willet, 

 Ferruginous Kough-leg, Chestnut-collared and McCown's 

 Longspurs, Lark Bunting, Sprague's Pipit) ; third, by the 

 absence of those arboreal species which inhabited the pop- 

 lars about Shoal Lake. Most of these, however, would doubt- 

 less have l)een found if we had searched the limited tree- 

 growth along Alaple (.'reek, or in the sand-hills, which dune- 

 like occasionally arise in the Plains, Nor did we visit the tim- 

 ber of the " Cypress Hills," some twenty miles south of the 

 town of Maple Creek, but examination of A. C. Bent's ex- 

 cellent list of the "Summer Birds of Southwestern Saskatch-

 pp. 25-35), shows that most of the Manitoban birds are pres-

The characteristic Plains birds in southern Saskatche- 

 wan are Chestnut-collared and McCown's Longspurs, 

 Lark Buntings, Horned Larks, {Otocoris alpestris leu- 

 colcema), Meadowlarks, {Sturnella neglecta) , Bay-winged 

 Buntings, {Pocecetes grammeus confinis), and Rough-leg- 

 ged Hawks, {ArcJiibuteo fcrrugineus). All but the last- 

 named are abundant, while the first four are flight singers, 

 and there is virtually not a moment of the day when one or 

 more of them cannot be seen or heard. The Meadowlark's

 earlier in the season, is less often heard in June, when the
