CETTI'S

 

 Old plastic chair and abandoned reserve implements at WWT Slimbridge.

Although more often heard than seen, the Cetti's warbler can be a challenging bird to record well: especially using static microphone placements. Its movements are secretive and rapid as it forages through dense patches of bramble and willow.

Behind a concrete wall in a sheltered section of the reserve, I found a loose collection of objects — broken bird feeders, plastic chairs, metal storage boxes, buckets — presumably set aside by the staff. They were forgotten and weather-worn, covered in leaves and detritus.

I placed the microphones one metre apart on nearby, low-hanging branches. There was ideal cover for a Cetti's amongst the plastic and metal.
