Trigger target - neither bird nor insect
The introduction to this project should make clear that many of the images include a black bird or moth shape on a tree with a small circle in the middle. I have deduced that this is a reflector target used with the infrared triggering sensor. In future I will not categorize it as living.

It's a scent bag lure. If this project ever gets an update, I would definitely include a mention somewhere that many of these photos have that black scent-bag lure.
As is, folks (like you) generally figure it out fairly quickly.
Thanks for the feedback!!
