At their peak in September
Red deer rut in the Dinaric forestsStags roaring across dolines and beech slopes — the Dinaric forest gives long, clean reverberant tails; antler clashes, hinds barking, Ural owls and dormice in the same nights.
Wolf howling and Ural owls, Kočevski Rog nightsPack howls with high pup yips from rendezvous sites, carrying several km across karst dolines; Ural owl's deep barking 'wuh-wuh-wuho' and female's hoarse calls; Tengmalm's owl in late winter; red deer in the same windows from mid September.
Edible dormouse nights and the 'polharjenje' seasonSqueals, churring and 'kissing' contact calls from the canopy, loud scrabbling on bark, beechnut shells raining down; in mast years the forest sounds like it is full of monkeys.
Waders and terns on the Sečovlje salt pansLittle tern colonies screaming over the pans, stilts and avocets yelping, redshank and Kentish plover, reed warblers in the Dragonja channel; salt-worker rakes and the sea beyond the dyke.
Also going on in September
Bat emergence from karst cavesAudible squeaks and wing rustle at cave mouths from Miniopterus colonies of thousands; with a bat detector, horseshoe-bat constant-frequency calls at 80–110 kHz and bent-winged FM sweeps.
Brown bears from forest hides, KočevskoBears are mostly quiet: heavy footfalls in beech litter, sniffing, huffing and jaw-popping when nervous, cubs squalling, mating-season moans; the surrounding evening chorus (wood warbler, Ural owl at dusk, red deer) is the real soundscape.
Marmots, ibex and chamois in the Julian AlpsMarmot alarm whistles echoing off limestone walls, chough flocks, ptarmigan croaking above the treeline, chamois hissing alarm sneezes; in autumn the roar of red deer from the valleys below.
