For me:
Basel and Zagreb as one excursion (end of July, to check off all the zoos which are the only zoo in their country to hold a sun bear in one swoop, except for Łódź as Mali remains off show until the completion of the Orientarium so there is nothing I can do there).
Revisit to Usti, Hodonin, Olomouc and Jihlava as another excursion (probably August now although I had really wanted to go next month, I want to see the Usti cub active and I want to take my chance to see Li and Bara again while I still can, plus Adam/Ernst and Aja are real characters anyway).
Basin D’Arcachon, Saint Martin La Plaine and Zooparc Tregomeur as another excursion (likely September or October but I can’t really think that far ahead yet, that then boxes off all of the current on show sun bears in Europe for me).
Phnom Tamao Zoo and Wildlife Rescue Centre (pencilled in for my birthday in November for a sun bear overdose).
Everything else I want to do, such as Japan, USA, Poland and Borneo trips will have to wait until next year!
