In the snow-covered fields around the lake there were lots of Skylarks Alauda arvensis, clearly on migration as we counted up to 70 birds in loose flocks. Only some of them were singing. Among other migrants were Hoopoe Upupa epops, Wheatear Oenanthe oenanthe, Yellow Wagtail Motacilla flava, Kestrel Falco tinnunculus, Marsh Harrier Circus aeruginosus, Swallow Hirundo rustica, Sand Martin Riparia riparia, Cuckoo Cuculus canorus, Ruff Calidris pugnax, Curlew Numenius arquata and Lapwing Vanellus vanellus. A late flock of 7 Cranes Grus grus was still lingering on the lake and frequently observed feeding in the wet meadows. In the afternoon we also spotted a pair of Ring Ouzels Turdus torquatus, which is always a nice find, especially on migration. Friends birding the lake also reported a male Pallid Harrier Circus macrourus (good passage across Slovenia in the first week of April) and a Red-rumped Swallow Cecropis daurica (rarity inland).

Among the birds breeding in the area of the lake were several White Storks Ciconia ciconia that have returned to their traditional nests in the villages, while Fieldfares Turdus pilaris were feeding in the orchards (localised breeder in Slovenia). An immature White-tailed Eagle Haliaeetus albicilla passed above our heads briefly, while much more exciting was the find of a breeding-plumaged Red-necked Grebe Podiceps grisegena, a very rare breeder in Slovenia, known to nest only at lake Cerknica. Commoner were pairs of Great Crested Grebes Podiceps cristatus and Greylag Geese Anser anser. From the nearby forest we also heard the distinctive call of a Short-toed Eagle Circaetus gallicus, another rare breeder at the lake.

In the past ten days or so we've been frequently out in the Karst's dry limestone grasslands, counting farmland birds. The landscape still looked quite wintry, however the birdlife was already abundant. The main dawn chorus in this type of habitat is composed of singing Skylark Alauda arvensis, Woodlark Lullula arborea, Hoopoe Upupa epops, Cuckoo Cuculus canorus, Corn Bunting Emberiza calandra and Mistle Thrush Turdus viscivorus. Here and there some occasional pairs of Stonechat Saxicola torquatus, Common Whitethroat Sylvia communis, Wryneck Jynx torquilla, Cirl Bunting Emberiza cirlus and the rare Tawny Pipit Anthus campestris can be also found. Migrants seen included mostly Wheatear Oenanthe oenanthe and Common Redstart Phoenicurus phoenicurus, while a nice adult Black Stork Ciconia nigra seen catching a thermal under the Karst edge was quite a surprise.

The true botanical spectacle is yet to grace the dry limestone grasslands (in May and June), however some of the first interesting flowers are already out. One of the earliest species to bloom in this habitat is the rare Narrow-leaved Fritillary Fritillaria orientalis, a plant that we are lucky enough to have blooming every year in the open woodland just behind our house. However the best specimen are those found in good numbers in the open grasslands, like the one in the photos below. In contrast with the wet-loving Snake's-head Fritillary Fritillaria meleagris, this really is a plant of dry, rocky grasslands.

Recently we also finished with the last transects of the Middle Spotted Woodpecker's census. The main highlight during the last count was a Ural Owl Strix uralensis gliding in front of the car when we were driving on a forest road. It's been a while since our last proper Ural Owl, so this encounter was very much enjoyed. Given the shortage of food in the forest (after last year's "rodent year"), our local pair/s will probably not breed in the Karst this year. Also nice was finding several woodpecker species building/checking their nests, including a smart Black Woodpecker Dryocopus martius, seen and photographed from the car. Needless to say, the song of returning Cuckoos Cuculus canorus has been pleasing us during our recent visits to forests across the Karst.
