Orcas in Captivity Versus The Wild

Grade 3/4 students at Dundas Street Public School recently learned more about orcas and their habitats. They compared the life of an orca in the wild with the life of an orca in a marine park. 

Their postcards on behalf of Corky show us some of the struggles that orcas face in captivity:

Orcas in marine parks are socially isolated from their family pod:

They live in barren environments:

They are confined to small pools and can't engage in natural behaviours like hunting:

They suffer high mortality rates:

They have to perform circus tricks to earn food:

In the wild, their lives are vastly different:

Orcas live their whole life with their family pod:

They hunt in a vast and stimulating ocean environment using echolocation:

They can swim for many kilometres each day:

They have freedom: 


Thanks to all the students for their great artwork and comments. Their postcards will be sent to Seaworld, where Corky, who has been in captivity for more than 40 years, lives. Hopefully Corky gets a chance to reunite with her family pod, and swim in the ocean once again. She deserves her freedom after all these years.

Urban Wildlife

These are some of the cool plaster casts of tracks that students at Dundas Street Public School made recently during their Keep It Wild! workshop. Studying animal tracks is a great way to connect with wild animals and learn more about the wildlife that lives in the city. Tracks are easiest to spot along creek and river beds, and in muddy trails after a recent rainfall. There are lots of resources on the web that explain how to make plaster casts of tracks. Check some of them out this summer and see if you can capture some tracks!
