Which zoo celebrated the 1st birthday of panda twins Leni and Lotti?

The Berlin Zoo celebrated the 1st birthday of panda twins Leni and Lotti. This event is significant because it highlights the zoo's efforts in breeding and conservation programs for giant pandas, which are classified as vulnerable due to habitat loss and other factors. The birth of the twins was particularly celebrated as it contributed to the global conservation of this species and engaged the public's interest in wildlife preservation. Celebrating milestones like the first birthday of such rare animals fosters awareness and appreciation for wildlife conservation efforts. Other zoos mentioned may have their own initiatives and animals but did not specifically celebrate the birthday of these twin pandas.
