I've recently noticed a lot of posts being tagged with "Avian" when they just have low-detail "W"-style birds somewhere in the background. It's somewhat annoying when you search for a specific species and that's what you get. I don't think anyone who is looking for an Avian will be looking for those as background details, so I was wondering if those should be exempted from the Avian tag or if we maybe need a specific tag strictly for that. ("Background bird" or something like that)
