I particularly like that this sign is multilingual. I've seen this at Detroit Zoo whose signs are in Spanish and Arabic (the nearby town of Dearborn has the largest Muslim population per capita and the largest proportion of Arab Americans in the U.S.), but I don't think I've seen it anywhere else in my travels. It's a great way to make the important lessons more accessible to the local zoogoers, particularly in such an ethnically diverse place as New York where some number of visitors may predominantly speak (in this case) Spanish. I'd like to see this sort of thing rolled out in more zoos, particularly in New York, perhaps even the addition of Chinese or Japanese language signs as the Bronx Zoo often gets tourists of Asian descent.
@iluvwhales I visited the Denver Zoo several months ago, and many of their signs were translated into Spanish because the US southwest has a large population of immigrants from Central America. I agree that it can be very useful and important for zoo education and visitor accessibility.
