Welfare Monitoring and Ontogeny in Grizzly Bears

In 2011, the Detroit Zoo rescued three orphaned grizzly bear cubs from Alaska, after a poacher killed their mother. The bears, who were orphaned at a young age, required intensive monitoring to ensure that all their needs were being met and they experienced great welfare. For that reason, we began behavioral data collection in 2011 and continued through 2013. This allowed us not only to monitor their welfare, but also to investigate their social dynamics and how their behavior changed as they grew from bear cubs into adult grizzly bears.
