 movement and roosting places 

 OF Scissors Tail Fly-catcher. 

 {Milvulus tyrannas.) 



Not all the birds come to these roosts each night and/n" ^^^^ 

 Naparimas at least, numbers may be seen settling to sleep about 

 6 p.m. on the black sage bushes. 



The females and young have much shorter tails than the males. 

 In a northward evening flight crossing the road between San Fernando 

 and Princes Town on September 19. 1920 I counted 78 with long 

 tails and 1 8 with short.
