Blue Jays Of The Vermilon River. A Post to World Bird Wednesday
1) Their blue colour is due to the structure of their feathers that react with light to produce the vivid colour. Crush the feather and the blue is gone.
2) They mimic the calls of hawks and will band together to drive off predators.
3) They also can be taught to mimic human sounds as can their cousins the crow and the raven. Although, I understand they draw the line at minicing Stephen Harper the PM of Canada.
