591. BotaurUS StellariS. (Linn.) pi. En]., 789 ; 

 Ardea Stellaris, Linn. ; The Common Bittern, Bewick's 

 Brit. Birds, PI. 47 ; Ardea Stellaris Capensis, Sch., 

 Mus, de Pays-bas ; " Roerdomp " of Colonists. 



General colour, ochreous, profusely variegated with wavy 

 lines of dark-brown ; top of head deep-brown ; chin white, 

 or pale-ochreous ; the markings on the back assume a bolder 

 character than those on the other parts of the body ; the 

 neck is furnished with a ruff, which can be expanded at 

 pleasure. Length, 2' 4" ; wing, 12" ; tail, 4". 



The Bittern is occasionally found in a, few favoured localities, even in 

 tlie neighbourhood of Cape Town ; and I am told it breeds in Verloren 

 Vley. At Zoetendals Vley I found it in great abundance ; and early in 

 the morning, or during the evening twilight, their booming call 

 resounded from every part of the lake. Mr. Hugo, of Fransch Hoek, 

 brought me a pair of eggs, unfortunately both broken, which he states 

 are of this bird. The colour is a dark olive-green, smooth, and 

 shining as a duck's. Having seen bitterns' eggs in various collections 

 in England, I am satisfied that Mr. Hugo is right in his identification.
