I watched a Northern Harrier hunt near the banks of Silver Creek a few days ago. This particular Harrier came back to the same spot over and over again. It was on the serious hunt. I hid near a small willow and waited for it to pass over. While I am sure it noticed me I don't know that it was bothered by my presence. It was getting attacked in the air by 4 or 5 territorial Red-Winged Blackbirds. I am sure this Harrier was flying right over a few nests but it could not locate any of them under my watch. The Red-Winged Blackbirds, despite their diminutive size, fearlessly and/or dutifully, did everything they could to disturb the hunting raptor. The smaller Blackbirds definitely bothered the Harrier.
