 Carriker says of this species in Costa Rica, 

 "They are usually found in the forest, although 

 at times frequenting scattered trees in pastures, 

 the edges of the forest and banana plantations. 

 They have a weak, rather musical note, which 

 is often uttered as the birds in small bands are 

 feeding or flying about among the trees."
