upwards, unless disturbed, provided it can find any easier 

 way to get out of the house ; for it appears that it cannot 

 readily begin its flight, but in an oblique direction ; conse- 

 quently it walks deliberately out at the opening left for it, 

 and the skeiny being fitly contrived, and placed for the pur- 

 pose, catches hold of and fairly strangles it." This bird is 

 of powerful form, but not so compact as the Golden Eagle. 

 Its aspect is also heavier, and it has not the same alertness 

 and activity. When reposing, it sits with drooping wings, 

 and the feathers of the body ruffled in the manner of the 

 Vultures^ with which birds, indeed, it was at first classed by 

 LiNN^us ; a proof of the striking affinity it bears to that 

 family. It is of wide distribution, species being found in all 

 quarters of the globe.
