The Red Leg is never easy to approach when in open ground.
They will run away at a rate of knots or take flight and glide away if they have no other option.
I was able to sneak up on this one from the car window. Even then it was pure luck and he would never face towards me.
The Red Leg is the more common species of our Partridge.
The rare species is the Grey Partridge, which is more difficult to find let alone photograph, something I have not managed for quite some time.
