348 Jensen, Nesting Birds of Wahpeton, N. D. [j u l J y 



Zamelodia ludoviciana. Rose-breasted Grosbeak. — Fairly com- 

 mon. On June 111 found a nest with three eggs of this species and one 

 Cowbird's egg. June 27 another nest was located containing three heavily 

 incubated eggs, and June 2S one more nest, with three newly hatched young. 

 All were near the river. 



Spiza americana. Dickcissel. — I have only seen one pair of these 

 birds, and I did not locate a nest, but for about two weeks in June, the male 

 could always be seen on top of bushes or weeds near the edge of an alfalfa 

 field near the river. The alfalfa was then cut, and I did not see the birds 

 again. 



Progne subis subis. Purple Martin. — Very common. The Purple 

 Martin was nesting all over the city. At the Indian School I set up a 

 number of bird-boxes in which seven pairs were nesting. In June sets of 

 four or five eggs were laid, but very few young ones were raised, as the 

 English Sparrows were continually fighting the Martins and would go into 

 the boxes and destroy the eggs. 



Petrochelidon lunifrons lunifrons. Cliff Swallow. — Common. 

 I located a colony of twenty-five nests on a barn near the Indian School. 

 On June 26 most of them had young. 



Hirundo erythrogastra. Barn Swallow. — Very common. One pair 

 were incubating a set of five eggs in a garage at the Indian School, when the 

 building was lifted on rollers and carried about one hundred and fifty feet 

 and turned, so the door, which had been facing east now is toward the south. 

 In spite of all this disturbance the Swallows hatched their eggs and reared 

 their young ones. 



Riparia riparia. Bank Swallow. — Very common. I found them 

 nesting in large numbers in the river banks. In one colony near the Indian 

 School I counted more than five hundred nests. 



Stelgidopteryx serripennis. Rough-winged Swallow. — Some of 

 this species were nesting in the river banks, but not in such numbers as the 

 Bank Swallow. I only located two nests, on of which contained a set of 

 five heavily incubated eggs on June 26. 



Lanius ludovicianus excubitorides. White-rumped Shrike. — One 

 nest of this species was located in a cottonwood about twelve feet from the 

 ground, and on April 23 a set of six fresh eggs was collected. About two 

 weeks later the birds were again incubating a set of six eggs. 



Vireosylva olivacea. Red-eyed Vireo. — Fairly common in the 

 shrubbery and timber along the river. 



Dendroica sestiva sestiva. Yellow Warbler. — Very common. 

 Nesting wherever a few bushes were to be found. In about one half of the 

 nests located, were deposited eggs of the Cowbird. Quite often the 

 warblers would build a new nest on top of one in which a Cowbird's egg 

 had been laid. (See ' The Auk,' October, 1916). 



Dumetella carolinensis. Catbird. — Nests were common along the 

 river and a few were found in the groves around the farm buildings. Sets, 

 of five eggs are common in this locality.
