Habits. Schomburgk remarks (Reis. Guian. ii. p. 503) : — This 

 species is fairly common and found mostly in pairs, and is not of a 

 very shy nature. It seeks its food, which consists of water-insects 

 etc., on the edges of rivers. Towards dusk they fly away to 

 roost in the woods. {Cfr. vol. iii. p. 75G.) This species lives as 

 the preceding species {Ibis rubra), singly or in pairs, on the 

 Savanna swamps and on the borders of the rivers. I have 

 found it at an altitude of 1500 ft., but I was unable to discover its 

 nest. The " Warraus " call it Korro-korro. 



Mr. Barrington Brown (Canoe and Camp Life, p. 21) gives the 

 following note: — "The Curi-Curi or River Ibis (Ibis infuscata) 

 gets its name of Curi-curi from its cry, which resembles that word 

 repeated a few times ; they are of a dull olive-green colour, with 

 light green bills and legs. They drill holes in the mud-banks with 

 their long bills for worms, feeding after the manner of Snipe.'' 



Mr. J. J. Quelch met with this species on the Abary River, and 

 remarks that it rose at intervals from the bushes. He also observed 

 it on tho Berbice River and at Gooriictown.
