There are only two birds that roost together overnight - Vaux's Swifts and the tiny Pygmy Nuthatches. Here is a photo take by the late Ron LeValley showing one of these birds headed face down a tree.

Last year a group roosted in a birdhouse on the north end of our house. This year they are in a Bishop Pine tree in our parking area. I've noticed on previous days that the nuthatches don't come out until they hear the Wrentit's call. But when I set up to photograph them this week, there were no Wrentit calls. They were VERY wary coming out, as you can see in this video.  I have it posted on the Mendonoma Sightings Facebook page: https://www.facebook.com/profile.php?id=100063067277149&sk=videos

Hope you enjoy seeing this!

We had 0.35 inches of rain overnight. More to come.
