SLATY ANTSHRIKE 



shrubbery and open brush. Usually seen in 

 pairs or a group. Three surprisingly different 

 calls were identified: one beginning in an em- 

 phasized staccato note followed by a long se- 

 quence of whistles, retarding and ending ab- 

 ruptly in a less musical, somewhat emphasized 

 note; the second a series of a few complaining 

 and beseeching squawks; and the third call an 

 indescribable harsh and rasping croak. The calls 

 of both sexes are alike.
