NOTES: Neotropical Institute Cut # 15. Bulk reel: 250
Weather: Fair. Natural calls. Note: These are two-syllable, like the birds from "Guayana." Quality: 2. Level: +12. 139 tape.
Note: Field note made 24/VIII/70, 6:40 AM, near La Mesa, above La Fria, Tachira, indicates that although most of the calls by this species in this area are of the single-hoot type, as true in general west of the Merida Andes, I heard at least one double-hoot call.
