My neighbor has two large ficus trees in pots on either side of her front door. The entry way gets a lot of traffic. What was in one of the ficus trees right at perfect eye level - but a nest. It was the dearest thing you ever want to see. She had her babies there and the traffic never bothered her one bit.

I thought it was interesting that they make this chirping noise with their tails. They can make the sound vocally - but it isn't loud enough so they use their tails.
