Walk round and tell them what you are doing first!
I suppose I could ask but it would still be hard to justify, kites are a pretty common sight, these days.
Here's a couple more mildly amusing bird photos for which I did use a tripod aimed directly at a neighbour's window, left in place for hours with hundreds of shots taken. I didn't think they'd mind. A bit grainy as I used a high ASA to allow the fast exposure, and shame the focus is not quite 100% but you can't have everything!
Who needs wings, when you have mastered levitation?
