Description
 
Size
2.5 - 10 inches in shell length (6.3 - 25.4 cm). (Stebbins 2003)

Appearance Color and Pattern
A small turtle with red markings on the marginals and a smooth, oval, somewhat flattened keelless carapace which is black, brown, or olive in color with a network of faint light lines and olive, yellowish, or red borders along front edge of the shields. The posterior rim of the carapace has a smooth (not serrated) border.
The limbs and head are black to olive and marked with yellow lines.
Yellow stripes extend rearward from underneath the eyes and often from below the jaw.
The upper jaw is notched in front.
The unhinged plastron is reddish with a large dark mark in the center which branches out between the scutes.
Male / Female Differences
Males are smaller than females and have very long nails on the front feet.
A male's plastron is more concave toward the rear than it is on a female.
Young
The plastron coloring on juveniles is more strongly contrasted than on adults.

Similar Species
Turtles of another alien species - Red-eared Slider, Tracemys scripta elegans, are more common in California waters than painted turtles. You can use a couple of details to tell them apart in the field if you can get close enough, the color behind the eye and the rear of the shell. See above.
If you get the turtle in hand, you can also look at the plastron, which will be marked with a lot of red on the painted turtle but not marked with red on the slider.

Life History and Behavior

Activity
Aquatic and diurnal. Sleeps at night on the bottom or on a partially submerged object. Probably active all year long in the south but inactive during cold periods. In the north, probably hibernates beginning in late fall, emerging in March or April.
Often seen basking on rocks, logs, or dirt banks, sometimes in large groups.
Relatively cold-tolerant. In some areas, they can be observed swimming under ice just before it melts in March.
Turtles Walking on Land Do Not Always Need to be Picked Up and Rescued
Turtles sometimes leave the water to search for food, a better place to live, a mate, or to lay their eggs in the spring - typically from March to June. If you see a turtle walking on the land, it is probably not sick or lost, so the best thing you can do for the turtle is to leave it alone. Some people want to help a turtle they think is in danger by picking it up and bringing it home or to a wildlife rehabilitation center, but most of the time this harms the turtle by removing it from the wild without reason. Sometimes turtles do get lost or stranded in yards or on busy roads or somewhere where they may be in danger. If you find one in such a situation, it's ok to move it out of danger, but it's best to leave it in a safe place as close to where you found it as possible.
Diet and Feeding
An omnivorous generalist - eating almost anything found in its habitat, including insects, worms, snails, crayfish, fish, amphibians and tadpoles, carrion, and aquatic vegetation. Young are carnivorous, but become more herbivorous as they grow older.
Reproduction
Becomes sexually mature when it reaches the appropriate size, typically in 3 - 6 years.
Breeds from March to June.
When the environmental conditions are just right, the female digs a nest at a sunny site near water in loose soil, anytime between May and August. Hot weather and drought can cause her to delay her nesting for a few weeks.
She lays from one to 23 eggs.
Egg incubated naturally in a Painted Turtle nest observed in Pennsylvania took 72 - 80 days to hatch.
(Ernst 1994)

Habitat
Ponds, marshes, lakes, ditches, quiet streams with sandy or muddy bottoms and aquatic vegetation.

Geographical Range

Chrysemys picta - Painted Turtle - is the most widespread species of freshwater turtle inhabiting North America, ranging across the entire continent from southeastern Canada to Louisiana to Washington, with isolated populations in Utah, Arizona, Colorado, New Mexico and Texas.


Distribution in California

The species is reported to be introduced and established in waters throughout populated areas of coastal southern California, however I can find very few sight records or museum specimens for this species from anywhere in California. It is possible that most of the sightings of this species did not result in specimens being collected and deposited in a museum or they were only written up as a sight record in a herpetological journal that I have not seen. It's also possible that some turtles identified at a distance as painted turtles might be Red-eared Sliders since they are similar in appearance at a distance.

My range map shows the species inhabiting the same general range in the heavily-populated region of coastal southern California that is shown in most field guides, (including Stebbins and McGinnis, 2012, and the 2018 Peterson Guide) even though I cannot find very many records from this area. I suspect that the species has been found in that area and in other locations throughout the state where pet owners have dumped them, but they have not been successfully established in most of those locations, so they are not observed consistently in the area.

Observations of painted turtles in California reported on iNaturalist (viewed 6/7/21) include a few locations where this species has been identified in Sonoma County, one location outside of Sacramento, a few locations in the San Francisco Bay Area, mostly in the East Bay, a location in Carmel Valley, and a few locations in Orange and San Diego Counties.

I've also seen pictures of an Eastern Painted Turtle - C. p. picta, that was found on the Stanislaus River below Knights Ferry, obviously another pet release.


I would appreciate getting email from anyone who has seen a painted turtle in the wild in California, including pictures that I can use here, if possible.


Kaiser Meadow Population

In the late 1970s, some painted turtles were released at Kaiser Meadow in Siskiyou County. A local science teacher notified Robert Stebbins resulting in the inclusion of the location in his subsequent field guides (including his final 2013 guide). Searches there since the 1980s have uncovered no painted turtles, only native pond turtles. It appears that there is no established population at Kaiser Meadow, so I have left that location off my range map. (James Buskirk, personal communication.)

Notes on Taxonomy
Three subspecies of Chrysemys picta are recognized, but some researchers want to return the full species Chrysemys dorsalis - Southern Painted Turtle, to subspecies status.

In 2003, Starkey, David E., H. Bradley Shaffer, Russell L. Burke, Michael R. J. Forstner, John B. Iverson, Fredric J. Janzen, Anders G. J. Rhodin, and Gordon R. Ultsch [Molecular systematics, phylogeography, and the effects of Pleistocene glaciation in the Painted Turtle (Chrysemys picta) complex. Evolution 57(1): 119-128] determined that Chrysemys picta consists of two species. If this is accepted, C. p. bellii will become Chrysemys picta with no subspecies recognized.


Alternate and Previous Names (Synonyms)

Chrysemys picta - Western Painted Turtle (Stebbins & McGinnis 2012)

Conservation Issues  (Conservation Status)
As an introduced species, it is possible that this turtle competes with and therefore poses a threat to native Pacific Pond Turtles.
