A garter snake
 |
|
| [Note Guidelines] Photographer's Note |
A garter snake is any species of North American snake within the genus Thamnophis.
Garter snakes are extremely common across North America, from Canada to Central America, an everyday find in gardens. They are the single most widely distributed species of reptile in North America, and in fact, the common garter snake, T. sirtalis, is the only species of snake to be found in Alaska. It is also one of the northernmost species of snake in the world, possibly second only to the Crossed Viper, Vipera berus. The genus is so far ranging due to its unparticular diet and adaptability to different biomes and landforms, from marshes to hillsides to drainage ditches and even vacant lots, in both dry and wet regions, with varying proximity to water and rivers. Though, as you approach the western portion of the continent these snakes are more water-loving than on the eastern portion. Northern populations hibernate in larger groups than southern ones. Despite the decline in their population from collection as pets (especially in the more northerly regions in which large groups are collected at hibernation), pollution of aquatic areas, and introduction of bullfrogs and bass as predators, this is still a very commonly found snake. The San Francisco garter snake, Thamnophis sirtalis tetrataenia, however, is an endangered subspecies and has been on the endangered list since 1967. Predation by crayfish has also been responsible for the decline of the narrowhead garter snake, T. rufipunctatus.
There is no real consensus exactly how many species of Thamnophis there are, and disagreement among taxonomists and sources, such as field guides, over whether two types of snakes are separate species or subspecies of the same species is common.

Check out that forked tongue! Nice shot, the eye is crisp and depth control great.

Hello Mircea,
Great shot! I like the colors and the tongue curled up. The image could have used some more depth-of-field though. Did you need 1/1000 sec here?
Best wishes,
Hakan

Great capture! Did good job to make sure the background was burred and the colors complemented the snake. I also like the way you got the glitter in the its eye. The DOF focuses on the snake's head and tongue. The only distracting part of this photo is the lower left hand corner. This could have been cropped out or cloned using a photo editing tool. ADubin

Hello Mircea,
Wow ! Impressive portrait. You caught the good moment for the tongue.
The "+++" : subject, composition, point of view, sharpness, blurred background, colors, exposure, useful note...
The "-" : BG a bit noisy, distracting spot in left corner, perhaps more DOF with f/8...
Congratulations and TFS.

Hi Mircea,
You caught a nice moment the flicking tongue make it look good.A bit noisy though, maybe a bit of noise removal would help.
