Really nice build!
Pretty birds and I like having them around though I have not seen them that much - but they are one of the few birds that foul their nests - hence you don't really want them to nest in the eaves of the house!
I like birds and would never disturb them if they did, but they never have at our house anyway!
Here are some pics I posted of the real thing.......
