Dorothy and E2 keep up their pair bond in the "off" season by bowing at the nest. So far this month they've visited it every three or four days.
Here's a selection of the best snapshots. At this time of year their visits are very quick so there's usually only one snapshot per episode.
On October 4 E2 bows very low with his back to the camera.
They're a blur on October 7.
They pause in perfect bowing position on October 10.
"Come bow with me," says E2 last Friday, October 18.
Serious courtship is months away. Meanwhile they stay close to home.
