A customer's parrot learned to mimic our alarm siren

I was doing a final walkthrough when the parrot squawked the exact tone of our entry delay beep. The homeowner freaked out, thinking the system was arming itself (which would be weird, right). We spent ten minutes figuring out it was just the bird practicing. I had to show them how to adjust the siren volume, just in case. Now I joke about adding 'pet training' to my service list.
