Wild Slovenia in Spring - Naturetrek tour

We are just back from a busy two weeks in the field, mainly based around the Notranjska region. We've been co-leading a general wildlife tour for Naturetrek as well as doing short custom trips, both to Notranjska and Primorska, including two interesting days in the company of Peter Alfrey (his posts here & here). The places we visited include: lake Cerknica, mount Slivnica, Javorniki & Snežnik mountains, Loška dolina, Planinsko polje, Rakov Škocjan, mount Nanos & Vremščica and some Karst around Divača and Sežana. Due to the high temperatures and summer weather we were mostly enjoying in butterflies (saw around 50 species) and plants, whilst birds were thinner on the ground. Among birds we observed both Ural Owl Strix uralensis & Three-toed Woodpecker Picoides tridactylus as well as Black Stork Ciconia nigra (on a daily basis) and commoner open-areas birds like Corncrake Crex crex, Barred Warbler Sylvia nisoria, Common Rosefinch Carpodacus erythrinus, Quail Coturnix coturnix, Whinchat Saxicola rubetra, Hoopoe Upupa epops & Curlew Numernius arquata (probably breeding at lake Cerknica). Among mammals the most interesting was a chorus of 2-3 howling Golden Jackals Canis aureus in the middle of the day, in the Karst near Divača. Below is a long selection of photos, arranged more or less in a "habitat order", starting with forest, then wet meadows, grasslands and finally mountain pastures. Enjoy!

Three-toed Woodpecker Picoides tridactylus, Javorniki mountains.
The activity at the nest continues; juveniles have fledged and the adults are more active at the nest-hole at the moment.

We've seen two different birds; one at the nestbox site and the other flushed from the road.
