I think the main issue of this toot is I use the default 640x480 resolution, which makes the picture too small to distinguish the details. Running on 1080P natively does cost a lot of RAM and time, but it can tell it's a bird very quickly and confidently.
@skyblond It does look similar to a Blackbird check the Wiki picture below! :)
