A group of about 100 species, mostly of the Old World. Terres- 

 trial birds, with the habit (shared by various others) of moving the

The MimincE, now associated with the wrens by the A. O. U., 

 are in many respects intermediate between wrens and thrushes. 

 Their reference to either group is chiefly a matter of convenience. 

 The wrens " are sprightly, fearless and impudent little creatures, 

 apt to show bad temper when they fancy themselves aggrieved by
