While we were travelling in Newfoundland we came across an attraction called Salmonier Nature Park.
Most of the animals were rehabs that couldn't be released back into the wild.
Due to the habitat local animals and birds were using the space.
We spotted several young gray jays chasing through the trees.
The Gray Jay stores large quantities of food for later use. It uses sticky saliva to glue small food items to tree branches above the height of the eventual snow line. It may be this food storage behavior that allows the jay to live so far north throughout the winter.
