FAMILY FORMICARIIDAE 253 



The only record at present is that of Peters (Bull. Mus. Comp. 

 Zool., vol. 71, 1931. p. 323) of a male taken by H. von Wedel at 

 Cricamola near the western end of the Laguna de Chiriqui, Bocas del 

 Toro, August 19, 1928. 



The rufous sides and flanks make this the most brightly colored 

 race of the species. In Costa Rica, Slud (Amer. Mus. Nat. Hist., 

 vol. 128, 1964, p. 224) remarks of this shy bird that each individual 

 or pair appears to have a "restricted forest area in which it roams 

 about ... It flies only when frightened, and then not far, in a low 

 fluttering dash ; usually it strikes an immobile pose or simply walks 

 away quietly. . . . Ordinarily it progresses in rapid hops . . . but 

 it may also patter delicately and come to sudden stops like a little 

 plover."
