Colombo, Michael and Scarf, Damian (2019) Sheeple? The need for more research on sheep cognition. Animal Sentience 25(12)
Lori Marino and Debra Merskin, Intelligence, complexity, and individuality in sheep
Marino & Merskin (2019) provide a comprehensive review of the cognitive abilities of sheep. If research with other animals is any guide, there may be justification for the view that the abilities of sheep have been underestimated, and their review will likely stimulate more research into sheep cognition.
