breeds near water, generally in old grass in a marsh or by a pool. 
Nest composed altogether of dried grass with a lining of finer grass 
and a little horse or other hair. (Macoun.) 
542. Labrador Savanna Sparrow. 
Passerculus sandwichensts labradoricus R. H. HOWE, JR., 1901. 
Fairly common at Port Manvers, lat. 57° northeastern Labrador, 
during the last half of August and the first week of September, 1900. 
(Witmer Stone.) Probably not separable from the Savanna sparrow. 
CCXXII. CHENTRONYX Bairp. 1858. 
545. Baird Sparrow. 
Centronyx bairdu (AUD.) BartRD. 1874. 
It is difficult to understand how this bird eluded observation 
for thirty years from the time of its original discovery by Audu- 
bon on the upper Missouri nearly to the present day. I did not 
meet with the species along the Red river itself, but found it as 
soon as I passed from the Pembina mountains to the boundless 
prairies beyond. In some particular spots it outnumbered all the 
other birds together, and on an average through the country from 
the Pembina mountain to the Mouse (Souris) river it was one of the 
trio of commonest birds. The skylarks and chestnut-collared long- 
spur being the other two. (Cowes.) An abundant summer resident 
throughout the Assiniboine valley, wherever there are alkaline flats. 
In many parts of the prairies west of Birtle there are low flat alkaline 
stretches sparsely covered with long, wiry grass. Wherever the 
land is of this character the Baird bunting is sure to be a prominent 
if not a prevailing species. (E. T. Seton.) One specimen secured 
the first time we went collecting at Grand rapids of the Saskatchewan; 
shot on a high grassy plain between the fort and the lake. (Nutting.) 
Not observed in many numbers in the vicinity of Portage la Prairie, 
Man., but was more numerous in grass marshes in 1906 west to 
Edmonton, Alta. (Atkinson.) Uncommon in parts of Saskatchewan 
visited by us but quite a number of pairs were located in grassy 
hollows in the prairies. (A.C. Bent.) Common in proper localities 
as far west as Calgary, Alta. (W. E. Saunders.)
