Awareness signs are posted along the main roads in northern Okinawa for their protection. I think they should also include speed bumps in the designated crossing areas for the rails.

The speed limit is only 40km/h so watch your speed for the protection of the wildlife. The rails are often seen feeding on the side of the road.

I have observed these birds crossing the road on many occasions. They have no problems crossing when people are driving the speed limit. Speeding decreases your reaction time, slow down and pay attention to all crossing wildlife.

What to do if you find an injured rail.
People often ask me what is the purpose of conservation photography? Having the ability to affect some form of positive change in the environment and make a global difference with the photographs. Hopefully, the images will inspire people to care more about nature and make a positive difference in the environment.
