My Strange Little Visitor

For the past two days, I have a strange visitor at my home. A bird has decided that they have found a playmate in the reflection of the brass kickplate on my front door--themself! All day, I hear this pecking noise on the front door as well as this loud, incessant chirping sound. I open the door and it flies away. I finally snuck around front and caught the bird in the act...how does one rid such a pesky little visitor? Maybe I'll tape a picture of a cat out there and see what they do...heehee
