Field-recording notes
Ponds are private fish farms: observatories and roads only, no walking the banks. The Brenne is sparsely populated and dark at night — one of the quietest lowland areas in France. Hunting on the ponds from August; spring is clean apart from occasional light aircraft from Châteauroux.
