OBSERVATIONS. 



Specimens are quite uniform in coloration. Readily known, in the adult stage, from the preceding species by the green- 

 ish-brown color: in all stages, by the five bars of spots on the tail, and from all others, by the small size, absenceof any prom- 

 inent ear tufts, together with the color as described. Distributed, as a constant resident, throughout North America to 

 the Arctic Circle. Rare in New England during winter.

HABITS. 



Richardson's Owl, although very common in the woods of Canada and northward, is, 

 beyond doubt, one of the rarest of the order in the United States, only visiting the extreme 

 northern portions during winter. They are not very uncommon in Maine and Northern 

 New Hampshire at this season but are very rare in Massachusetts, where only a few spec- 

 imens have ever been taken. A male was, however, obtained in Newton on the twenty- 

 sixth of February of the present year, 1879, by the Bangs Brothers who saw it hanging, 

 dead, to a bush by the road side, near a house, as they were passing. Upon inquiry, they 

 found that it had been shot some time previous by the owner of the place,- who supposed 

 it to be a Hawk and said that it had been killing his hens. South of us, this bird may be 

 regarded as a rare straggler but has been taken once in Connecticut. 



I have never been so fortunate as to meet with this species living, but writers describe 

 its habits as being similar to those of the Acadian Owl and say that it has a peculiar note,
