It's been a rather slow and typically summerish couple of weeks. Bird monitorings proceed as usual at Škocjanski zatok, while other field activities are quite reduced (except during the weekends). The most interesting observation so far was a Black Stork Ciconia nigra near its nesting site in the Brkini region, where we've been regularly observing the species for the last 10 years or so. This spring an active nest was found, thus confirming the species' breeding in the area. Black Stork is a very rare breeding bird in SW Slovenia, where perhaps only 2 or 3 pairs nest, while it is somewhat commoner in the lowland and hilly eastern part of the country.
Otherwise we've been focusing more on butterflies and other invertebrates, especially the bumblebees & moths in our garden. The garden highlight, like every year in this season, was watching Stag Beetles Lucanus cervus flying around at dusk, while on one occasion even a Great Capricorn Beetle Cerambyx cerdo came to say hello. We also had several moth trapping sessions, but the nights have been quite cold lately. We are still waiting for some more usual summer weather to make the most out of butterflies & moths. Last week we also went snorkeling and were excited by a close encounter with a nice Cuttlefish Sepia officinalis. The above photo was taken in the moment when it turned dark, right before releasing the ink and propelling itself away at light speed. Hopefully more to report from the underwater world in the coming posts.
