Where to go
- Petanjci – Mura riverside forest — Softwood floodplain forest, oxbows; access on flood-dyke tracks. Map
- Veržej – Bunčani floating mill area — Sand banks with bee-eaters; the mill itself is a nice mechanical sound. Map
- Velika Polana stork village — One of Europe's stork villages — dozens of nests; bill-clattering from mid March. Map
How to go on your own, and what it costs
Flood-dyke tracks along the Mura are public: park at Petanjci or the Veržej floating mill (Babičev mlin) and walk the dyke at dawn. Velika Polana: the village streets under the stork nests. Record from the dyke, never enter the colony trees.
Cost: Free.
Field-recording notes
Flat, agricultural, and the Mura is the Austrian/Croatian border in places — border-police boats occasionally. Little traffic at night; the main noise is gravel extraction on the Croatian bank and farm machinery from May. Heronries are sensitive (DOPPS monitors them): record from the dyke, don't enter the colony trees. Corncrakes in the Mura meadows are a LIFE-project population — same rules as the Ljubljana marsh.
