Hobby?

Hello, you may have seen my post earlier about the peregrine falcons I saw. I looked at the images again and I think it’s not of two peregrines but a peregrine and a hobby. I thought the smaller bird was a male peregrine since it was smaller, but now I think it’s too small to be a peregrine. It’s also a lot thinner winged and longer tailed. Can anyone help me with this? Thanks
