Scaly-breasted Wren, Microcerculus marginatus, née Southern Nightingale-wren, more likely heard than seen, this tiny bird spends its time on the floors of humid rainforests, hopping quietly, but singing brightly. Its loud, cheerful song consists of bright, clear, pure tones with seemingly random pitch, volume, rhythm, and length variation. Alternately slow-and-steady and fast-paced-and-frenetic, it never ceases to surprise.
Early in the morning of August 20, 2025, this particular fellow decided my microphones would be the chosen audience for this out-of-the-blue yet clear and beautiful song.
As usual, an isolated version is included for detail, but this time AFTER the source recording itself.
For the technique curious, this was hour 23 of a 48 hour recording in the mid-elevation transition zone Amazon Rainforest at Manu BioStation in the Andes Mountain Foothills.
For the technically curious, this was recorded with a Zoom F3 with Oaka Verdi (copper version) microphones.
