I imagine most people here are pretty used to having their bird observations reach “Research Grade” rather quickly after upload, with many users eager to be the first to ID them as they pop up on feeds. I will sometimes upload batches of birds, reptiles, mammals, insects, and plants, and they tend to reach “Research Grade” in that order, with birds and reptiles being community-identified rather fast, and insects and plants taking significantly longer.
However, the one exception to this is my hummingbird observations. After all my other birds have been quickly identified, my hummingbird observations will sit at “Needs ID” for much longer and I’m trying to figure out why that would be. There are two hummingbird species that are observed near me, the more common Ruby-throated (Archilochus colubris) and the less common Black-chinned (Archilochus alexandri.) The ones of I’ve uploaded are female so the distinction between the two is subtle compared to the males of each species. That’s the only thing I can think of that might be delaying the ID. Does anyone with more knowledge of hummingbirds have any insight on this? Are the females of those two species too difficult to ID through image alone?
