More interesting wildlife was nearby after dark. We heard an owl's trilling hoot -- familiar, now, as I've been hearing it before dawn quite frequently this spring. We also got a look at its silhouette on a branch, showing up against the cloudy sky. When the owl moved from tree to tree, I could just make out the shadowy form as it flew. The moon is almost dark, so it was a very shady perception -- definitely too dark to take photos with any equipment we own.
From the cry we identified it as a screech owl. In the early morning I sometimes thought it was a distant alarm clock, as it makes a repetitive trilling sound, repeated regularly.
