Angie Snowie is one of two primary Greater one horned rhino keepers at the Toronto zoo in Toronto, Canada. Angie started working with marine mammals in 1993 and in 2004 shifted to zoo animals. She started working with greater one horned rhinos in 2012 and they have captivated her heart. Rhinos have ignited a passion within her to work hard to fundraise for all five species of rhinos in the wild. Angie, along with her partner, started a fundraising campaign called "iheartrhinos" to create awareness of the crisis all five species are facing and to sell iheart rhinos merchandise online and at events to raise funds for conservation. As a winner of the AAZK Bowling for Rhinos campaign in 2015 and 2016, she has been fortunate enough to travel to Kenya, Sumatra, and Java to see rhinos in their native habitat. Angie has successfully raised over 85,000 dollars for rhino conservation. Angie has been a member of IRKA since 2013 and feels that belonging to this organization has not only changed the life of the rhinos in her care, but helps give direction and inspiration for a long future in her fight too save rhino species and to be their voice in our zoo settings.
