 Helminthophila pin us (Linn.). Blue-winged Warbler. Common 

 migrant, and in part, summer resident. Arrives the first week of May, 

 and remains until September. At Prospect Park, near Des Moines, a 

 nest of this species was discovered on the nth of June, 1884. The 

 attention of the observer was first attracted by a male of this species 

 moving restlessly about through the trees at the edge of an open field, 

 overgrown with long grass and weeds. After watching the movements 

 of the bird a few minutes, the observer started to cross the field, but 

 when about thirty feet from the woods, a bird flew from almost beneath 

 his feet. A nest containing three eggs was soon disclosed, but, as the 

 identification of the bird was not beyond doubt, the place was visited the 

 next day, and a female of this species captured on the nest. The nest, 

 a beautiful example of avian architecture, was built in the grass at the 

 foot of a weed about three feet high; a broad leaf of the plant spread 

 directly above the little structure, effectually concealing it from view. 

 It was composed of dry oak leaves as a foundation; upon this 

 were numerous rootlets and stems of plants interwoven with the sur- 

 rounding grass, and lined with finer materials. It contained four fresh 

 eggs — rosy white, before the contents were removed, dotted with spots 

 of reddish-brown, and a few of lavender.
