Before arriving at Cerkniško jezero (Cerknica lake - Slovenia), a stop to look in the stream near Planina produced some Graylings and few Brown Trouts; the birds included two Common Sandpipers, some Yellow Wagtails in the grassland and a handful of Sand Martins on migration.

In the Cerknica lake's area nice numbers of migrant passerines including: Whinchats a bit everywhere, many Spotted Flycatchers, 1-2 female Common Redstarts, flocks of Yellow Wagtails (mostly flava), 5 Northern Wheatears, 1 Lesser Whitethroat. Other local birds included: Grey Heron, Great Egret, tons of Buzzards, Hobby (1), Short-toed Eagle (1 hovering above the lake), Greenshank (1 heard), 2 Marsh Harriers, Kestrel, Song Thrush, 1 Sparrowhawk, Marsh Tit, Linnet, Yellowhammer, Skylark, Red-backed Shrike, Black Redstart.
Fish in the local streams/water bodies: PIKE (both youngs and one adult with a large prey in the mouth), 3 Perches and some large shoals of Rudds.
