A couple of weeks ago, I posted a soundscape called Amazon Dreams, featuring a recording made in 2002 at the Madre Selva Biological Station in Peru. Here is yet another amazing soundscape from that trip, this one recorded by my friend Ted Mack.
Ted’s recording features the songs of a variety of species, including two species of tinamous, two owls, and a dove. The high point of the recording is when a group of titi monkeys sound off in the distance (pronounced “tee-tee”). The spectogram is also beautiful in its own right, and conveys the rich diversity of sounds from low to high:
Rainforest chorus from the Peruvian Amazon. Madre Selva Biological Station, about a day downriver from Iquitos. Recorded in early January of 2002 by Ted Mack.
Let’s try to make sense of what we’re hearing. I’ll use the sound collection at MacCaulay Library to point you to reference recordings (just hit the species names, which are linked to specific xeno-canto recordings):
Undulated Tinamou – melodic 4-parted whistles
Cinereous Tinamou – simple loud whistles, all on one tone
Tropical Screech Owl – throaty gurgled songs heard in the background near the beginning
Tawny-bellied Screech-Owl- hollow tooting series heard after the Titi Monkeys end
Titi Monkeys – resonant outburst of calls starting halfway through
Gray-fronted Dove (?maybe not?) – low, soft moans heard throughout
