For those wondering what the state of the art is, I did this in 10 min between meetings.

The most challenging thing was getting the right indexing on the lists since it could be an empty list, a list with a single value, or any number of values.

    from ultralytics import YOLO
    
    model = YOLO("yolov10x.pt")
    results = model("birds/*", classes=[14])
    
    for result in results:
        if 14 in list(result.boxes.cls):
            print("Bird!")
        else:
            print("Not Bird")

I will now take my 5 billion dollar please.

Ironically enough the meeting I'm going in to is to explain why I need to use $100,000 worth of hardware for three months before I can answer the business side if what they want to do is possible or not.
