Spring Equinox — Dawn Chorus Field Recording

This is a field recording captured at dawn on the spring equinox, March 20th, 2026, in the foothills west of Boulder, Colorado, at an elevation of approximately six thousand feet. The recording begins in darkness, about forty minutes before sunrise. You can hear the first tentative calls of a mountain chickadee, followed by the distinctive whistle of a white-crowned sparrow. As light begins to filter through the ponderosa pines, more voices join — a Steller's jay, several robins, and the distant drumming of a hairy woodpecker. At the twelve-minute mark, the sun crests the eastern ridge. There's a noticeable shift in the soundscape as the dawn chorus reaches its peak. The creek below the recording site, swollen with snowmelt, provides a constant bass note beneath the birdsong. Around the twenty-minute mark, a gust of wind moves through the trees, creating that distinctive ponderosa pine sigh. If you listen carefully, you can hear the difference between wind in the needles and wind in the bare aspen branches nearby. The recording closes with the chorus winding down as the sun rises fully and the birds settle into their daytime patterns. The last sound you hear is the creek, constant and unchanging, as it has been for thousands of years. No narration. No music. Just the earth, waking up on the day the light returns. Recorded with a matched pair of omnidirectional microphones in ORTF configuration. Minimal processing — just a gentle high-pass filter to remove sub-bass wind rumble.
