hunting at night. During the time just preceding nesting it was 

 noticeable that they were inclined to roost two and two instead of 

 in a long line. In some cases the pair was sitting in close contact, 

 even though there might be plenty of room to perch comfortably." 

 Voice. — Dr. Richmond's impression of the note of the groove- 

 billed ani is mentioned above. Sefior Alfaro says, in his notes given 

 Mr. Cherrie (1892), that, in Costa Rica, it is "known as 'Tijo, tijo' 

 (tee-ho) in imitation of its peculiar notes which seem to repeat the 

 word tijo over and over again." Dr. Chapman (1896) says: "Its 

 note is a prolonged chee-wyyah, easily distinguishable from the single 

 whining whistle of C. ani^ Mr. van Rossem (1938) says: "The 

 ordinary or 'conversational' notes are a series of very liquid and what 

 can best be described as 'contented' bubblings and duckings. The 

 louder, often repeated 'chee-miiy-o-chee-muy-o' is the alarm note."
