NOTES: Neotropical Institute Cut # 4. Bulk reel: 111
Weather: Cloudy, fair. Natural song from a group of birds. I couldn't see how many nor sex ratio, but from this group I collected: two males #4816, 4817. Quality: 2. Level: 0.
Also heard are "caw-type" call notes and some "churr" call (bother?) notes. Much cicada noises in background.
Note: Also heard are some calls of Formicivora grisea (as well as other birds). Don't confuse its F. grisea notes with those of T. punctatus.
