Peacocks...we used to have a neighbor who kept them. The would yell in March and that was pretty much it for noise. They would escape every now and then and come to visit. That could be pretty much any time of the year.
We had one dog who would get hysterical at them as long as they were on the ground. Once on the roof or in a tree, however, he was fine. We found out that peacocks/peahens fly better than you would think they could.
They also love dry cat food. At the time, we had some outdoor cats and we had a metal pan in the carport for them. The carport is beside the bedroom Early on Saturday mornings, we would hear this horrendous rattling outside the bedroom window which turned out to be a group of peacocks/peahens surrounding the cat pan and scarfing down kittykibble as fast as they could.
(We did find out from another peacock fancier that they use the kittykibble for peacock treats, so we weren't too worried about poisoning them)
