AOTITURUS BARTRAMIUS, ( Wils.) Bp. 



Babtramtan Tattler. 



This interesting bird is extremely abundant over ail the prairie of the 

 Bed River region. I found it upon my arrival at Pembina, June 1, and it 

 bre-eds during this month. I took eggs from the second to fourth week 

 of June, and found newly hatched birds early in July. The first week 

 in June, a female was killed, with an egg in her ready for extrusion. 

 During the breeding-season, they seem to scatter indiscriminately over 

 the prairie; yet there are particular spots, generally depressed, there- 

 fore slightly more fertile, which they particularly affect. They appear 

 to leave the country sooner than most of the waders ; I saw none after 

 the fore part of September, though the majority of the waders continued 

 plentiful through most of this month. They make up in flocks before 

 their departure. 



In the Missouri and Milk Eiver regions, they are not nearly so nume- 

 rous — in fact, none were observed after leaving the former river ; the 

 prairie waders which breed further westward being chiefly the Long- 

 billed Curlew. 



A tolerably full and, I think, perfectly reliable biography of this 

 species will be found in my "Birds of the Northwest".
