in Georgetown, and remarks : — " In swampy places on the out- 

 skirts of the town, but chiefij along the coast, the common small 

 Yellow-headed Reed-bird {Xa7ithosomus icterocephalus) will gene- 

 rally be found in considerable numbers among the low bush and 

 tall reeds and grasses." 



The following note has been copied from Beebe (Our Search 

 for a Wilderness, p. 351): — "Little Yellow-headed Blackbirds. 

 Few more beautiful sijj^hts can be imagined than a cloud of these 

 birds risino" ahoad of the train or launch, and scatterino- far and 

 wide over and through the reeds. The general colour is a rich 

 black, which itself contrasts strongly with the green of the 

 savanna. But when we add to this tiie brilliant yeliow^ head and 

 neck .... the colour scheme is one which is never forgotten.'^
