Male in nestbox this morning. Very windy. Heard the train go by with that long, long whistle. All of a sudden female appeared, and joined him in box, lots of conversation and bowing, then male took off, much to the female's surprise, it seemed. Anyway, she perched on nestbox ledge and watched him flying around, putting on a show for her, I presume. Dot looks to be a very attractive, full-grown falcon. I hope they have eggs.
