Habits. Mr. J. J. Quelch (Timehri (2) v. pp. 90, 91), who 

 observed this species in Georgetown, remarks : — "Among some 

 of the commonest of the birds seen about the sti-eets and gardens 

 of the town are various species of greyish Tyrant-birds, with 

 rather small flattened bills, commonly known as Muft'-birds. 

 These are species of the genus Blainea, the two commonest are 

 U. pagana and B. albiceps. 



"These birds feed on seeds and insects, but particularly the 

 latter; and when they have secured some tit-bit are often to be 

 seen chased by the Kiskadees and compelled to drop the treasure. 

 At such times they erect their crests to great advantage as though 

 witli a desire to fight, but they have neither strength nor courage 

 to face their tyrants."
