Adult Female. Plate CXCIX. Fig. 2.
The female does not differ materially from the male in colouring, but is somewhat larger.
The Young, like those of other Owls, are at first covered with down, and are many weeks before they are able to fly. I have not been able to ascertain whether they raise more than one brood in tlie season, but am inclined to think that they do not.
