(spoilers) Blue bird in the construction of john's house

[IsmaA7X]

Hello. I'd like to know if anyone else has noticed that little blue and white bird that's in a lot of the building scenes of john's house. I also remembered that in guarma in a transition You can see two small birds. On the bridge we defended in one of the missions. Others in this transition, birds "walk" with arthur. And the image clearly focuses in that direction. Let's remember arthur had a wife and son who died. We might think they're "they" and the blue and white bird is arthur? 

Thanks a lot!
