Answer:
This is an example of interspecific competition. The reason is because both birds live in the same wooded area, but the blue jays are very aggressive and will take over the bluebirds nests. This shows the blue jays are being dominant and stronger, so this is an example of the strongest trying to dominate and be the ones to remain in the wooded areas. The bluebirds will either find new ways to nest, or maybe most will leave the wooded area. Hope this helps. :)
