ARVO

birdmap description: (2025)
Young Black Stork from Karula National Park. In 2025, there were two chicks in the nest, one of which (the bigger one, named Arvo) we put a tracking device on. According to the measurements, he is a male. There are no tags on the parent birds here. This brood was fed additionally throughout the chicks' stay in the nest (May-August). We only kept a gap during the summer high water, when it was not possible to avoid flooding the fish basket. Arvo went further south from the nest for the first time on August 14, about 15 km away to the Mustjõe floodplain. But he returned to the nest and also to the fish basket twice more. On August 17, he finally left the nesting site, but remained in the Mustjõe and later Koiva river floodplains until August 24. We continued to feed them on the banks of the Mustjõgi River. Other Black Storks and herons also experienced pre-migration fattening. Arvo's migration took him to Belarus and Poland. But from there, he headed west-southwest through the Czech Republic and Austria. A rather unusual migration route.
Arvo stays in Switzerland for a longer period, three weeks. He will then travel to the Rhone River Delta in southern France. This is one of the few wintering areas for Black Storks in France.
