Crandall on the Blue Bird of Paradise. 



[The Blue Bird of Paradise. By Lee S. Crandall. Zool. Soc. Bull. 

 New York, xxiv. 1921, pp. 111-118; col. pi.] 



The Zoological Park at Bronx. New York, has heea so 

 fortunate as to acquire recently a live pair of Prince Rudolf's 

 Blue Bird of Paradise (Paradisornis rudolfi), and Mr. Crandall 

 describes in a short note the extraordinary display antics of 

 the male with the aid of a beautiful illustration in colour by 

 Mr. Herbert Kunth. During this performance the bird 

 firmly grasps his perch Avith his ])ower£al feet, and with legs 

 extended to the utmost hangs head downwards. Viewed 

 from the front, the plumes and the bird itself form an 

 inverted triangle, the inverted apex of which is the black 

 breast of the bird bordered above by a narrow band of dull 

 red formed by the featiiers which ordinarily clothe tlie 

 abdomen; beyond, the blue and yellow of the plumes com- 

 plete the triangle in the middle and sides ; while the long 

 pendent "wires" rise above to half their length and then 

 droop gracefully downwards on either side. During the 

 display, Avhich lasts for several minutes, the body is moved 

 backwards and forwards with the hips as a fulcrum, and this 

 rapid movement causes waves of colour to run over the 

 entire triangle. Truly a most marvellous display, probably 

 the most brilliant to be found in all the range of bird-life. 

 We trust it may not be long before the Zoological Society 

 in Loudon may be able to obtain a pair.
