98 BIRDS OF SOUTH AFRICA. 



ing a stridulous cry of cm>cur-crak-crak. I sought in vain for its nest 

 in the months of November, December, and January. 



I identify this bird with " L'Isabelle " of La Vaillant. Its habits 

 accord well with those described by him as belonging to that bird.

My son procured several specimens of this shy and retiring bird in 

 rushes on the banks of the " Diep Rivier," near the Observatory, 

 Cape Town. He informs me he was attracted to them by their 

 babbling, which he at once detected as new to him. Their stomachs 

 contained the remains of minute coleoptera and other insects. Mr. 

 Ayres has observed it in JSTatal.
