Black-faced spoonbill, one of the most rare species in the world, fly south to Taiwan for winter ( to hibernate ) every year. Ironically, thanks to global warming, it's likely that they will be forced to put up with sunglasses and some other sun protective devices "in winter time." This is what you're about to find out when you're trying to do birdwatching, taking a peek at one of them. Hilarious but pathetic. Given the fact that black-faced spoonbill is considered as the one of the national treasures of Taiwan, this poster aims at motivating Taiwanese people to take action against global warming (#13 of SDGs, "Climate Action," ) which then prevents the extinction of black-faced spoonbill.
