The mourning doves at my house make a big noise and a nice outline on my living room window... The feeder is not located in a good place for them... Have had many dazed and confused mourning doves. Worst window kill was a crow. I thought a there was a bomb blast the house shook when it hit the window. The flock (or what ever a family of crows is called) had a funeral cawing in the trees over the house mourning the loss.Oh just an FYI, when Mourning doves fly REALLY fast, the do not make any noise at all.......
