What kind of snake is this?
Thank you for your question. Unfortunately, the photograph you sent came through out of focus and the coloration appears to be altered. As a result I can't make out the markings on the head, the sides and the true color of your snake.
Your snake is not one of the native venomous species found in Louisiana. I believe it may be a juvenile speckled kingsnake, scientific name Lampropeltis getula holbrooki. Typical adult length is a little over four feet, and maximum length can reach between six and seven feet.
They live in a variety of habitats including hardwood and pine forests, sandhills, meadows, as well as urban and agricultural areas. Even though they are primarily a terrestrial species, they are often found along the grassy shorelines of ponds, swamps, streams and occasionally coastal salt marshes.
Kingsnakes are strong constrictors and feed on a variety of prey. They are best known for eating venomous snakes. They are immune to their venom. However, they also eat non-venomous snakes, rodents, lizards, birds and bird and reptile eggs.
Here's a link to the web page for this species on the Amphibians and Reptiles of Louisiana website:
