Interesting & Amazing Information On Blue Jay Bird 
  • It is difficult to differentiate between a male and female blue jay bird, as both of them are almost the same. The only distinguishing feature is that the male is slightly larger than the female.
  • The bird is known to mimic the sound of hawks, to scare and mislead the other birds that a hawk is close-by. This sound is usually heard when a blue jay is in search of food.
  • It is territorial in nature and would often chase off the enemy (cats, dogs and sometimes, even humans), if found near its nests or food sources.
  • Blue jay is aggressive and dominant in nature and would turn off many of the backyard birders.
  • The bird stands proudly as the mascot of various sports groups, like the Toronto Blue Jays, Canadian Professional Baseball Team, etc.
  • It sometimes eats the eggs and young ones of other birds and even steals their food. However, this is very rare, as a study of its feeding habits had shown only one percent birds with egg or bird in their stomach.
  • Blue jay makes monogamous and long lasting pairs that are for life and would break only when one of the partners dies.
  • The color of its plumage is actually the light of refraction, due to the internal structure of the feathers and is not derived from pigments.
