During inclement weather, it spends the day 

 and night in hollows of decayed trees or deserted 

 holes of Woodpeckers, and in such localities de- 

 lights to place its nest, and has often been 

 known to excavate a place in hard wood for this 

 purpose. The nest is but a rude lining of soft, 

 warm materials. A single brood is reared in a 

 season. As soon as fledged, the young hunt in 

 common with their parents and remain associated 

 with them until spring. 



The eggs are round-oval, densely sprinkled with 

 minute brownish dots, interspersed with larger 

 spots of lilac upon a white back-ground. From 

 6 to 8 constitute a sitting, which average .74 

 inches in length and .56 in breadth. 



Its flight is lofty, moderately firm and well 

 sustained. 



The food consists of the eggs, larvae, and ima- 

 gos of Cratonychus cinereus, and perfect insects, 

 of C. pertinax, Harpalus pensylvanicus, Platynus 

 cupripennis, Bostrichus pini, 3&& Formica sanguinea. 

 The seeds of various grasses constitute its vege- 

 table diet.

 ventures in the heart of winter into our yards,
