Nant Trefechan Brook Morning CHorus


Zoom Tre 2.1

This recording begins at Just after 4 o'clock in the morning. The continuous background noise is the river, which sets the mood following a couple of heavy nights of rainfall, on a dry morning. Given that the dynamic and velocity in sound of the river ebbs and flows with the amount of rainfall, we can also hear that the birds are having to exert their vocalisation a little further in order to break through the barrier of noise, which is louder than the previous recording. We can also hear the the vocalisations seem a little more urgent or pressing as though the speed of the river is controlling/influencing their internal tempo. It is an interesting example of how birds with their highly elaborate and advanced vocal ability should also be endowed with similar time keeping abilities as we humans, and like humans their internal circadian rhythm can be tempered by what they are exposed to externally.

This recording has been taken at the point where the Trefechan Brook turns back on itself in a 'U' shape. The Microphone was placed set back about 4m on top of a bank exactly at the bottom of the 'U' where it captured the sound scape at mid tree level. There is a a natural acoustic interest to this area as it creates a type of natural amphitheatre for the animals to make their vocalisations, which can then be heard reverberating up the valley.
There is great depth in sound, as well as fascinating interplay between species. Blackbirds, Bluetits, Chaffinch, Coaltits, Greatits, Green Finch, Ren, to name a few.
