Sorry Bert you are mistaken because only the Western Slider has the red patch on the side of their head whereas the Painted Turtles do not. Therefore my three turtles do not have any red so they are Western Painted Turtles.
Trachemys scripta, the Pond Slider, has 3 subspecies, of which one is the Red-eared Slider. The other two do not have red ears, one being the Yellow-bellied Slider. Unfortunately Hank, your turtles are Yellow-bellied Sliders. They are very commonly sold as pets.
Western Painted Turtles (Chrysemys picta belli), the subspecies of Painted Turtle found in BC, have a red plastron (the bottom portion of the shell) whereas sliders have a yellow plastron, as clearly shown in the photos Bert posted.
Yellow-bellied Sliders don't have red ears. Besides, red ears is not the distinguishing characteristic between Pond Slider and Painted Turtle. The red belly is the key feature. The turtles in your photos have yellow underbellies which means they cannot be Western Painted Turtles. Ear colour only eliminated Red-eared Slider, it does not eliminate Yellow-bellied Slider.
