Seldom, if ever, did we enter a willow-copse of any e.xtent, during our 

 explorations in the AVest, Nvitliout starting one or more specimens of this Owl 

 iVoin the depths of the thicket. This was the case both near Sacramento 

 and in the Interior, and in .summer as well as in winter. In these thickets 

 they find many deserted nests of the Magpie, and selecting the most dilap- 

 idated of these, deposit their eggs on a scant .additional lining. This 

 practice is so general, so far as the bird.>5 of the Interior are concerned, that 

 we never found the eggs or young of this species except as described above. 

 On the 27th of May we found a nest containing four downy young among 

 the willows along the bank of the Truckee River.
