The one I have seen out later is Aurora. I thought she stopped early like all the others but I have seen her on in to evening. Last week I saw her out when it was dusk and she had a light on her gazebo area. I'm not sure of the time other than the light made her stand out but it wasn't full on dark.
In August we saw her about 7:00. It was a total shock, I assumed she was done for the day and we were hanging out on her gazebo area and she walked up and joined us to watch a lizard.
No idea what they'll do on a holiday
