223 Birdsong in deep forest ambience

Full Episode description

Whilst walking up towards the observatory in the Kielder forest, we passed large areas of cleared woodland. “Fallen in the great storm of 2021” a passing forester explained in the afternoon sunshine. In some sections, the trees had been cut and stacked. Rows of tree trunks that smelled deliciously rich with the resin-y smell of Christmas trees. We found the smell instantly relaxing, as if it reduced blood pressure just by inhaling it. 

We stopped on a steep rough path by a rushing burn, to take in the pristine quiet ambience. Banks of wind were brushing across the high tree tops. Grand firs, whose countless fine needles instantly convert wind energy into rich brown sound. The rushing water permeated the surrounding space with what we feel is the cleanest white noise mist we’ve come across this year. Capturing this sound scene was something we just had to do. 

Finding a suitable tree for the Lento box by the path wasn’t too difficult. Bathed in the white noise mist and the brown sound of the tall fir trees, we left the microphones alone to capture this passage of time.

Slightly to the left of scene is the rushing burn. Fresh water speeding shallowly over steep flinty stones. High above and undulating from right to left of scene, wind brushes the upper tree tops, filling the air with waves of softly hushing sound. Various songbirds are singing, wrens and blackbirds but willow warblers seem to be very common in the Kielder Forest. Their song while quite fleeting is a lovely droopy descent down a simple scale of notes. It’s very similar to the chaffinch song, only purer, and without the musical somersault that the chaffinsh seems to finish on.
