Innovations for zoo animals
Found this awesome ted talk which highlights new ways of feeding zoo animals in 2010 as just giving the animals were making them bored and their behaviour was different, this was due to the animals spend many hours of the day hunting/searching for food in the wild. This ted talk covers three different methods for the animals to find food presenting them challenges. the first being scatter feeding, where the animal have to search the grounds, the other is through puzzles and the third is battling a pinata, and these are just a few innovations in feeding animals.
However it is not just new feeding methods, other innovations for improving the welfare of animals has been focusing on making sure they exercise properly just take a look at this short vid.
