These were all captured by motion-triggered cameras and brought together by the Smithsonian into one database. The photographs are from various projects around the world featuring various exotic creatures going about their normal behaviour, from cats in Panama to pandas in China.
The Smithsonian is functionally part of the United States federal government and is therefore "official". It's the largest organisation of its kind in the world with 16 museums & galleries, 10 research centres and even a zoo. The Official Publications Unit has Smithsonian publications from the 1850s onwards. If you want to learn more about this wonderful institution, you can read The first hundred years of the Smithsonian Institution, 1846-1946 by the wonderfully named Webster P. True.
