40 THE AUDUBON BULLETIN 



Schroder of Bettendorf, Iowa, writes that he took a picture of 

 a Hummingbird in his yard on September 11, and saw them 

 there several days later. Davenport and Bettendorf are about 

 twenty miles southwest of Port Byron. 



Mr. Schroder also took a picture of a Nighthawk nesting on 

 a factory roof last summer. He reports that the Prothonotary 

 Warbler has been breeding on Credit Island, near the lower end 

 of Davenport, for the last two years. 



This year a pair of Baltimore Orioles built their nest in a 

 maple tree beside the kitchen, but something happened to the fe- 

 male Oriole about June 21. On June 22, the male Oriole stopped 

 singing, and the female was never seen again at her nest. A pair 

 of Sparrowhawks raised a brood in a Flicker box on a walnut 

 tree beside the public highway, and we blamed the Hawks for 

 killing the female Oriole. My brother saw where the Hawks had 

 killed two birds near their nest, and one day a Killdeer was 

 seen flying after one of the Hawks. We thought that probably 

 one of the Hawks had taken a young Killdeer and was flying 

 away with it. This is the first time that the Sparrowhawk has 

 bred on our place; we hope it is the last time. 



No Shrikes nested here this year. Only one was seen in the 

 spring, and one during the summer. Mourning Doves were com- 

 mon ; two pairs had nests at the same time on a large old burr 

 oak, and several pairs nested in our orchard. The Cliff Swallows 

 built ninety-one nests under the eaves of our barn, and we again 

 had much trouble to keep the English Sparrows out of them. 

 About July 15, all of the young Cliff Swallows were out of their 

 nests, and on July 20 all the young Martins were out of their 

 house. On July 21 the Martins began to gather in flocks and 

 sit on the windmill. Those that bred here left for the south 

 much earlier than in other years.
