Intermediate Egret at Bandar Seri Begawan mangroves, Brunei.
Tried to capture one of these birds mid flight which turned out to be very hard as they like to stay away from people. This one turned out nice, although I would have loved to get more sharpness and better light on it's head... well, maybe next time.

Comment on Flick album Schoenus × intermedius: The Alpine valley in the far northwest of Slovenia and the far northeast of Italy (MTB1/4 - 9548/1), located between the Slovenian village of Rateče-Planica and the Italian hamlet of Fusine in Valromana, is of great botanical interest. The area is the watershed between two large rivers, the Drava to the west and the Sava to the east. It seems as if the precipitation cannot 'decide' which way to flow. Consequently, and with an average annual precipitation of about 2,000 mm, the wide, flat valley floor is well waterlogged. It contains rare calcareous wetland habitats. Numerous interesting and rare plant species grow there. The area is protected. On the Slovenian side, it is part of the Triglav National Park, and on the Italian side, it is a specially protected area, Torbiera Scichizza – Piana di Fusine.
Two of these interesting plants belong to the genus Schoenus, a large genus with more than 150 described species (POWO, 2024). However, most of them occur in the Southern Hemisphere. Only two are known from Europe: Schoenus ferrugineus and Schoenus nigricans, along with their hybrid Schoenus × intermedius, syn.: Schoenus × scheuchzeri. All three taxa are relatively rare, considered endangered, and protected by law. In the region where my pictures were taken, Schoenus nigricans is central within its natural range, whereas Schoenus ferrugineus is marginal (Tomasella et al., 2014). Schoenus ferrugineus is already documented in the literature for the Italian and Slovenian sides of the region (Jogan, 2001; Poldini, 2002; Bačič, 2006; Kocjan et al., 2014; Tomasella et al., 2014). Schoenus nigricans is not mentioned in the immediate vicinity of the region, although several tens of other locations are known in Slovenia (Kocjan et al., 2014; Dakskobler & Martinčič, 2018; Dakskobler, 2025). None of these sites are very close to Torbiera Scichizza. Note that hybridization occurs most often at sites where both species are growing.
As far as we can determine, with assistance from AI ChatGPT, 5.6 Sol, the hybrid has apparently not yet been reported from Slovenia in the accessible botanical literature, even though several locations are known where both species are present (Martinčič, 2001). Martinčič’s treatment of Schoenus ferrugineus in Slovenia describes several such, albeit rare, stands on the Bloška planota and at Cerkniško jezero; however, it does not mention hybridization. Given these facts, it seems quite unlikely that our determination that the plants shown here are the hybrid is correct.
Nevertheless, sources indicate that such hybridization occurs quite often and that the hybrid is, in some locations, even more frequent than either parent (Hegi & Suessenguth, 1939; Foerster & Neitzke, 2008). In the region of northeast Italy, specifically in the Friuli Venezia Giulia region, Udine province, several locations with this hybrid are known. The hybrid origin of these plants was also confirmed by molecular methods (Scotti et al., 2002; Mariani, 2003).
The plants shown here exhibit an unusual morphology that fits neither Schoenus ferrugineus nor Schoenus nigricans. Some of the observed traits fall between the two tentative parental species. These include: the ratio of the length of the lowest involucral bract to the length of the inflorescence (Lb/Lh), the shape of the inflorescence, and the color of the inflorescence, as well as a very large relative dispersion in the length of the inflorescence. Other traits correspond to Schoenus nigricans: basal leaf length and color of basal sheaths, or to Schoenus ferrugineus: the length-to-width ratio of the inflorescence (Lh/Wh) and number of spikelets in inflorescences. A mix of retained parental traits of both parental species and intermediate state traits supports the hypothesis that the photographed plants are hybrids. In our opinion, the most compelling evidence for hybridization is shown in Fig. 8. It shows the position of both parental species (green and blue rectangles showing the range; data from the literature) and of 20 measured inflorescences of the studied population (red circles) on a graph with the Lb/Lh trait on the abscissa and Lh/Wh on the ordinate. The studied plants clearly fall between both tentative parental species. Nevertheless, more detailed studies are required to confirm the hybrid nature of the plants studied with certainty.
