The bird's song with the entering of night. Quality: 1-2. Level: 6 (+10).
Very prominent is the song of Nyctibius griseus.
[Note pertaining to cuts 59064, 59065, & 59066]: The definite identification of these cuts was made during the trip to Rio Grande (El Palmar) in June 1965. Cut #3, although a different type of song, was found to be made by this species and the same individual may give both types of song; when it does so, it starts with the song type of Cut #3, then changes to the other type.
