Toucans have stop signals. If you cross against the light you've just disobeyed a traffic signal. Hawks have pedestrian do not walk signals. I imagine pedestrians cannot cross against the signal and I would venture a guess this would apply to a bicycle in the crosswalk. If you are at the hawk in the roadway and traffic clears and you cross you'd be the same as any vehicle and I hope you wouldn't be cited for failure to obey a traffic control device.
