again. Lack of time prevented a thorougli seai'eh for nests. 

 The following list of species was noted : 



1. PoflUijmbus ijodiceps. T'ieil-liilleil Grelte. AVmndaiit resilient. Xests 

 with eggs and young of all sizes were found during our stay. Often 

 while we were in the blind a family of ycfuug grelies, ai'i-onipanied by 

 one of the parents, swam almost up to the lioat. They st^cnied to be 

 feeding on aquatic insects and vegetable matter. 



2. Hydrochelidon nigra sHriitame)isis. Black Tern. Present in con- 

 siderable numbers. We found no nests, but thought from tlieir actions 

 they were breeding in the north end of the swami). 



3. Querquedula discors. Blue-winged Teal. One or two pairs nesting. 

 We did not find any nests but saw one pair with young while we were 

 in the blind. We could not count the number of the brood, as some 

 of them were concealed by the weeds. 



4. Botaurus Icntiginosiis. Bittern. One nest found and stmlied. 



.5. Ixobrychus exilis. Least Bittern. One pair nested and were 

 watched for one day. 



6. Butorides virescens viresceiis. Green Heron. One noted almost 

 daily feeding on the small frogs, Avhich abounded in great numliers. Did 

 not find anj- nest, but have note<l them in other years nesting in the 

 willows along the shore. 



7. Balliis elegans. King Eail. One individual noted several times. 



8. Porzana carulina. Sora. Common. Noted every day, but did not 

 find any nests. 



9. Fulica amcricanu. Coot. Almndaut. A large nunilier of nests 

 found, and young of all ages noted. It was seldom during the day that 

 the grating note of this species could not be heard or a number of them 

 seen from the blind. 



10. Oxyechus vocifenis. Killdeer. Not common. One or two could 

 usually be seen feeding along the east shore.

 feeding along the shore and found nesting in the timber on July 1. 



13. Circus hudsonius. Marsh Hawk. A nest found July 1 in a damp

 and ran off through the grass as we approached. 



14. Otus asio asio. Screech Owl. Heard calling from the tindier. 



15. Ceryle alcyon. Kingfisher. One occasionally flew across the swamp 

 to the open water and fished there. The species did not nest about the 

 swamp, but came to it from the Missouri Eiver some distance north. 



16. Dryobates pubescens niedianus. Downy Woodijeeker. Noted 

 July 1 in the edge of the timber, where it was probably breeding.
