There is no doubt that the black-faced spoonbill is one of the most representative species in Taiwan’s ecological conservation history. Every year, more than half of the BFS global population choose to winter in Taiwan. This gives Taiwan a leading role in international conservation. This book captures the BFS during the rotation of the four seasons and their life struggle all over the world, from the break of dawn to late at night, braving the snow and inclement weather. The authors follow them as they migrate from north to south and back again despite the long and hard journeys from BFS wintering sites to their breeding grounds, just so they can faithfully present the many faces of BFS in different time and space. We have no way of knowing how long a great piece of literature would take to finish. We only know that this book has taken us more than 20 years to prepare and 3 years to plan and produce. As if racing with light, we must rise before sunrise and only call it a day after sunset in order to put each and every piece of the BFS global distribution puzzle in place before the environment changes drastically.
