Do non-migratory canada geese still exhibit migration behaviors?
The answer is yes, also sedentary geese do use migration patterns (V-formations). When they move from roosting place to feeding areas (or vice versa) geese always tend to fly in formations. I speak for personal experience of resident and wintering birds in Europe and America. 

They do so because they save energy as explained here: http://jeb.biologists.org/content/128/1/445.short and here: http://www.nature.com/nature/journal/v413/n6857/full/413697a0.html

The second study also show how not all the positions in the formation are the same regarding energy expenditure. The one closer to the front of the V shape need to flap the wing more often.

Have fun
