308 Mr. J. F. Hamilton on Brazilian Birds. 



37. Ramphastos dicolorus, L. 



Common. Flocks were frequently met with both at the out- 

 skirts and in the depths of the forests. I noticed that a flock 

 generally roosted in the same place, invariably proceeding to its 

 feeding-ground early in the morning by one route, and returning 

 in the evening by another, not making any long flights, but 

 resting frequently on the trees in their way : at such times they 

 were far less wary than when feeding. When flying they keep 

 the head and neck well stretched out ; and I sometimes fancied 

 that, if they flapped their wings rather faster, they would look 

 at some distance like Wild Ducks. 



38. Pteroglossus wiedi, Sturm. 



Not so common as the last, and, I think, keeping more to the 

 thick forests. 



39. Campephilus robustus (Licht.). 



This bird at once attracts attention both by its loud tapping 

 and harsh note, which very much resembles the scream of a 

 child. I only met with it in the thickest parts of the forest ; 

 and it does not seem, like most birds, to rest in the heat of the 

 day. 



40. COLAPTES CAMPESTRIS (Licht.). 



This is essentially a bird of the open campos : I never saw 

 them where the country was at all well wooded. They may 

 frequently be seen perched on the numerous ant-hills which 

 cover the Campos, flying ofi" on the approach of a traveller with 

 a loud scream and gliding flight, and perching upon another 

 ant-hill or on some tree*. 



41. CoNU^us viTTATUs, Shaw. 



Very common. I met them frequently in the neighbourhood 

 of maize-plantations, on which they commit great havoc. Along 

 the Sao-Paulo railroad flocks were frequently seen flying over- 

 head. 



42. Brotogerys tiriacula (Bodd.). 



I only saw one small flock of these birds.
