I'm working on a model for educational graphics of an emu in conjunction with other information, but there aren't a lot of great reference images. The thing that's most unclear is how the upper leg around the femur is connected to the rest of the body because it's always obscured by feathers.
Mainly, is the leg connected to the rest of the area around the hip only half way through the femur, at the distal joint of the femur, or past the distal joint of the femur to the tibia? Elephants seem to have the third option, while horses seem to have the second option, and wolves seem to have the first option, so there are many possibilities without a clear generalization. Below are the three options with the red indicating how far up the body the leg is connected to the skin of the hip area.
