MrsVRWC has a bag hanging on a hook on our back porch containing plastic grocery store bags that she uses for picking up the dog poop in the back yard. The other day she noticed that there was a bunch of debris including twigs and grass and pieces of cloth in the bag as she was reaching to get a plastic bag out, and then a bird flew out of the bag at her and then flew off. The crazy bird had started building a nest in her bag of bags. Fortunately, she had not started laying any eggs, so she will be able to find another place to nest.
they are such vagabonds, they will build anywhere. they have started nests in baseball caps and opened cartons of capri sun juice boxes in our garage!
