Wintering. 



Winter in Denver seems to have no terrors for this species. 

 It appears to tho writer that the cold season does not trouble the 

 Honso Pinch much so long as the bird is well fed, though many, 

 doubtless, suffer frosting of foot during extremely cold spoils. 

 resulting in mutilations referred to later on. Tho birds roost at 

 night, whenever possible, close to buildings, in vinos next to a wall, 

 in a nook or on a moulding under an overhanging eave, and in the 

 folds of awnings, for which places the birds have many fights until 

 all are located for the winter, each going to its accustomed place 

 a considerable time before sunset. The young birds sloop in trees 

 after leaving the nest. They have never been observed to sloop 

 two or more together, but appear, on the contrary, to desire sepa- 

 rate plaoos, each by itself. It has seemed odd to find that the 

 birds never use the nesting boxes to sloop in, after the nesting 

 season is over. In December they go to roost early, 4.15 p. if. 

 and sloop with the head under the wing, puffed up like littlo feather 

 halls. 



Cl NST78. 



Can one form any definite idea as to how many House Pinches 

 there are in Denver? This question imposed itself on the writer 

 early in this study, because of the relation of this species to the 

 English Sparrow, and while it is self-evident that any estimate 

 alone these linos must be approximate only, it is however, not 

 without interest to try to answer it. 



There are in the city oi Denver 3500 blocks whereon are to he 

 found buildings oi one kind or another. If two Finches are allowed 

 for each block there would appear to be 7000 Finches in the city, 

 a number seemingly reasonable as a minimum estimate. At one
