I used Audacity's effect 'Noise Reduction' to lessen the impact of the river noise.
觀察細節
Unexpected. I heard this bird immediately on approaching Hawk Creek in a steep riparian corridor with waterfalls, a lot of downfall, and massive boulders which create small caves, ledges, and nooks. Did not identify the species for the first hour or so but then it came to me. The song was a rapid, high-pitched series of tinkling, buzzing notes lasting ~4-5 seconds that was audible over substantial river noise. As in the recording, the quality of the song was dry, not musical or bell-like (Winter wren). The bird was singing regularly on the evening of the 28th and the morning of the 29th of July. Overall, I heard the song probably 40-50 times - thus seems like an active territory. I made several recordings with my smartphone on the morning of the 29th. I never saw the bird, and only attempted to get visual confirmation for ~5 minutes due to difficult terrain. According to Britten et al. 2017 in "Colorado Birds", there is a 1987 Troglodytes record from Snowmass, Pitkin, CO, and that this species is a suspected breeder in Rocky Mountain National Park.
