I think generally it would just momentarily affect the wind direction as it's the vane they tend to land on and launch off of, unless they move enough air when they flap their wings to really get the cups spinning.
I did tape a couple of wire brads to the tail of the vane to act like bird spikes, I thought that might help keep droppings from blowing into the rain collector below the anemometer. I think it helped, but I have seen birds land on the nose of the vane now. :) On Monday, July 29, 2019 at 8:18:48 PM UTC-6, Andrew Milner wrote: > > Birds love them!!
