Blue Jay

The Blue Jay is native to eastern North America. It lives in most of the eastern and central United States, Newfoundland, Canada and breeding populations are common across most of southern Canada. Its coloration is predominantly various shades of blue with a white chest and lower abomen. Both males and females are of similar size and have similar plummage. Blue Jays feed mainly on seeds and nuts with acorns being a particular favourite. They breed in both decidous and coniferous forests and are commonly found in residential areas. They are an extremely territorial bird with a noisy and aggresive nature. If they are agitated or angry the blue crest on the head will rise only lowering when they become calm and relaxed. Blue Jays are monogamous and they generally bond for life. Both males and females take an active part in building the nest and raising the young. The female broods the eggs whilst the male will ensure she has a constant supply of food during the incubation period.

  2. Their Blue color is not from pigment in the feathers, microstructures in the feathers scatter light to produce the vibrant blue coloration.
  3. Blue Jays are highly intelligent and show problem solving behaviour, the use of simple tools is a common occurance
