Western Yellow-bellied Racer

July 25, 1998
Pescadero Marsh Natural Preserve, San Mateo County, California
Western Yellow-bellied Racer (Coluber constrictor mormon)
Amongst the numerous gartersnakes at Pescadero Marsh are many of these racers, none of whom want to sit still to have their picture taken. There really is a snake in this picture. Really.

Western Yellow-bellied Racer (Coluber constrictor mormon)
In contrast to the extremely secretive Pescadero Marsh racers, this one may have been the most cooperative photography model in the history of the species. It was splayed out in a nice sinuous S-curve in the late afternoon, fully exposed. I walked past it without even noticing it. Our dog Max actually walked unaware through its coils, which apparently disturbed it enough that my wife saw it move slightly. Then it just lay there looking all snakey for us.

Western Yellow-bellied Racer (Coluber constrictor mormon)
Though adult racers are generally solid-colored, the young ones display a prominent pattern. This snake is a on the verge of adulthood; its markings are visible but have mostly faded.
Subspecies:

Coluber constrictor paludicola

Everglades Racer

December 31, 1998
Coral Gables, Miami-Dade County, Florida
Everglades Racer (Coluber constrictor paludicola)
This elegant dark gray snake was sunning itself on a rock wall when I first noticed it. It then noticed me, and climbed up into some vegetation to hide. Unlike its yellow-bellied cousins, it didn't race off; once it was concealed in the bushes, it stayed motionless.

Fairchild Tropical Garden, Coral Gables, Miami-Dade County, Florida
Everglades Racer (Coluber constrictor paludicola)
Everglades Racer (Coluber constrictor paludicola)
I discovered three of these small stealthy snakes in the cactus garden section of Fairchild Tropical Gardens. They have distinctive large, orange eyes.

Cape Canaveral National Seashore, Merritt Island, Brevard County, Florida
Everglades Racer (Coluber constrictor paludicola)
The range of the Everglades Racer is the southern end of Florida including the Florida Keys, but also a small area around Merritt Island and Cape Canaveral on the east coast of central Florida. The racers in the rest of Florida are considered to be a different subspecies, the Southern Black Racer. The differences between the two subspecies are very subtle (Everglades Racers aren't usually as dark, their chins are usually less white, and their eyes are usually yellowish rather than orangish or reddish), so it seems likely that this division might be artificial.

This snake was prowling around in the sand scrub in mid-afternoon on a chilly day.

Everglades Racer (Coluber constrictor paludicola)
Racers aren't averse to a little suburban living. This one was inspecting the grass in my mother-in-law's backyard, probably looking for Brown Anoles to devour.
Subspecies:

Coluber constrictor priapus

Southern Black Racer

February 29, 2004
Smyrna Dunes, Volusia County, Florida
Southern Black Racer (Coluber constrictor priapus)
The good thing about finding racers on coolish days in late summer or early spring is that they might just bask, rather than speeding off in an instant as they tend to do on warmer days. This one was right up at eye level a few feet off of the boardwalk at Smyrna Dunes.
March 1, 2004
Alexander Springs, Ocala National Forest, Lake County, Florida
Southern Black Racer (Coluber constrictor priapus)
Speaking of racers basking on coolish days, this very cooperative snake held its position despite the tremendous amount of crashing about in the thick palmetto bushes that I found necessary in order to get my tripod into a decent position. Dr. Terry Farrell found this snake while he, Dr. Peter May, and I spent a fine day herping in Ocala National Forest.
