group, and especially since the breeding history of the four eastern 

 species has been disentangled, we doubt the tenability of our former 

 supposition, as we do also that trailli ever nests with us. The yellow- 

 bellied Flycatcher arrives the first week in May, and we have seen it in 

 the fall till the third week in September. It is found in the same situ- 

 ations as those frequented by E. minimus. [388]

 129. (31.) Antrostomus vociferus (Wils.) Bp. Whippoorwill. 



A rare summer resident. The proximity of a large city seems to keep 

 these solitary birds away ; they are common enough in more primitive 

 country on any hand. They arrive the first week in May, and depart 

 the third week in September. When startled from their retreat in 

 the day time they rise rapidly and fly a short distance with a zigzag 

 coarse, as if confused by the light. In former years we saw them in 

 places, now built up, between Le Droit Park and the city limits. [397] 



ISO. (32.) Chordediles popetue (JleiU.) Bel. Night-hawk; "Bull-hat." 



Chiefly a spring and autumn migrant; but a few breed with us. They 

 arrive about May 1, and remain until the first week in October. Iu the 

 fall they are often very abundant, especially on cloudy afternoons, and 

 are still to be seen coursing their airy evolutions over the city. In 

 former times the commons north of K street, about where Iowa Circle 

 now stands, was a great place of resort for the shooting of these birds, 

 scores of gunners stationing themselves there to destroy any unlucky 

 " bull-bat " which might fly low enough to be reached by shot. [399]
