Owl bird scarers

We have fed birds for years. When we moved to our current address a couple of years ago we set up our bird feeders and have a variety of birds visit including great tit, blue tit, chaffinch, starlings, black birds and last week were lucky enough to have a brief visit from a bull finch for the first time ever.

We also get wood pigeons which is to our neighbours dismay and since we moved in they have accumulated 4 life size owl deterrents as well as other scarers including reflecting tape and owls.

My question is, they have recently erected a new owl on the fence between ours and their property, however the owl faces directly into our garden, not theirs. My personal opinion is that this really unneighbourly, where do I stand with this please ?
