Order Longipennes. 



4. Lams argentatus smithsonianus. Summer resident, most plentiful during 



the spring and fall migrations about the larger bodies of water ; proba- 

 bly breeding in the country. 



5. Lams delaivarensis. \ These three species are pretty common, and breed 



6. Lams franklinii. r on nearly every large body of water in the 



7. Larus Philadelphia, j country. They arrive about the middle of May 



and remain together in large flocks till the end of September, except 

 during the breeding season when they disappear suddenly. 



8. Sterna hijundo. Summer resident, but not \ ery common. Only on large 



bodies o( water, and undoubtedly breeding, as I mot with a few speci- 

 mens once on Crooked Lake, the Jiead waters of the Carrot River, gn 

 July 7th, 1897. 



9. Hydrochelidon nigra siirinamensis. A very common summer resident from 



about the end of May to the middle of September, and breeding in 

 great numbers in all the marshes and on ponds of any size. Seems to 

 prefer however the wettest and most inaccessible marshes, where it 

 breeds in large colonies. 

 Order Steganopodes. 



10. Phalacrocorax dilophus. A tolerably common summer resident about the 



large lakes and bodies of water; breeding in all suitable but retired 

 places. 



11. Pelecanus erythrorhynchos. Not very common, seen chiefly during its 



migrations; probably breeding on the larger and retired lakes. First 

 observed in the country in large numbers on the 27th of July, 1896, but 

 subsequently more commonly in large flocks, transient. 

 Order Lamellirostres. 



12. Lophodytes cucullatus. A common summer resident found in all the smaller 



ponds and lakes. 



13. Anas hoschas. An abundant summer resident breeding in nearly all the 



small marshes, chiefly those in the woods. Sparingly and early during 

 the migratory season, and in flocks or associated with flocks of other 

 Anatinse in the fall. 



14. Anas strepera. This species seems to be rare here. I have shot a few in 



the autumn, 1896, and since then one or two occasionally during the 

 same season. 



15. Anas Americana. Not very common, but frequently met with and breed- 



ing in the region. 



16. Anas carolinensis . \ Both tolerably common ai.d breeding abundantly 



17. Anas discors. J throughout the prairie. 



18. Spatula clypeata. Quite common and breeding abundantly throughout 



the country. 



19. Dafila acuta. Common, but less common than the Mallard, with which 



it arrives early. Breeding in nearly all the ponds and marshes of the 

 country.
