some part of the head of a bird, such as the feather " horns " 

 of owls, motmots, and larks. In Screech Owls these 

 prominent "ears" certainly play a useful part in breaking 

 up the outline of the bird, rendering it very difficult of 

 detection when it is perched upon some jagged limb or

 tufts of chin-feathers which, like wide-spreading whiskers, 

 spread to each side, and the Bearded Vulture has a simi-

 The eye alone can record their marvels, in the collection

 little creatures hover over, their favourite flowers, or 

 vibrate before us, fanning the air in our very faces with 

 their invisible wings. 



Brief mention should be made of two Birds of Para-

The Six-shafted Bird of Paradise is found only in 

 New Guinea. "The plumage appears at first sight black, 

 but it glows in certain lights with bronze and deep pur- 

 ple. The throat and breast are scaled with broad, flat 

 feathers of an intense golden hue, changing to green and 

 blue tints and certain lights. On the back of the head 

 is a broad recurved band of feathers, whose brilliancv
