Sandy, I have thought it so amusing that they have chosen only the prettiest of the bird houses to nest in. These are from last year.
I took down the one the Bluebird used and won't put it up until it looks like the nesting is done. I've had it in the garden in the front of my house and last year was the second year the Bluebirds nested there . Since it was right in front of the house the cat started hanging out in front of the birdhouse and even though I put things in front of it so I thought he wouldn't be able to get them, I came home one day and he had gotten the female. The eggs were already laid and the male sat out there and cried for 3 days. It was heartbreaking.
Finally he came back one day with another female and they started building a nest on top of the old one. Then one day all the activity stopped. After a couple weeks, when I was sure they weren't coming back, I looked in the birdhouse and the male was laying inside dead. I don't know what happened, but I don't want another pair of birds nesting there. It is too big of temptation for my cat.
