Wild Bee Nest Blenheim Ancient Oak Forest SSSI , Oxford UK

This recording captures the transition from the calm, docile state of early morning to the rising activity of a hive preparing to swarm.

At Blenheim, I had the rare chance to record a living swarm of wild bees high in the canopy of a centuries-old oak, in Europe’s most ancient oak forest, many of the arboreal elders are over a thousand-year-old. Working with Blenheim’s bee expert, climbing into the branches high up in the canopy to place microphones among the colony: tiny contact microphones pressed against the wood to capture hidden vibrations, and omnidirectional microphones to record the surrounding air and wingbeats.

In the cool of the morning the bees were calm and docile. As the air begins to warm and sunlight touches the swarm, the hive gradually comes alive. Thousands of wings begin to beat together, building a dense, layered hum that thickens in the air. Beneath the familiar buzzing, the microphones reveal subtle details: the clicks and rasps of mandibles, and the tremors of their bodies resonating through the oak.

This sound is more than simple noise. Bees communicate constantly through vibration and sound, through wingbeats, piping, and subtle body movements that ripple through the colony. Beekeepers and researchers often note that the collective hum of a hive can reveal its health: a steady, coherent tone suggesting stability, while shifts in pitch and intensity can signal disturbance, preparation to swarm, or changes within the colony.

These wild bees have built their nest over decades, high in the canopy, weaving it into the life of the tree itself. They collect plant resins, chew them until soft and malleable, and use this substance; often called “bee glue” or propolis,to build and seal cells within the nest, or to create free-standing structures mixed with pebbles and plant fibres. In fact, the bees glued part of my microphone into the tree as if it were just another piece of their architecture,a reminder that this recording wasn’t simply an act of observation, but an encounter with an ancient community at work.
