We visited the Hortobágy National Park in late autumn and found a diverse invertebrate life in puddles. I took photos of these using an improvised aquarium. The local Hortobágy Wild Animal Park also offered an opportunity to see some members of the once-abundant megafauna of the Great Hungarian Plain. Along with other mammals, Przewalski's horses and Heck-cattle are kept here under semi-wild conditions. The Heck-cattle are part of an ongoing program to "breed back" domestic cattle to resemble their extinct ancestral form, the auroch. Location: Hortobágy. Date: 22.10.2017.
