We were out for a morning walk with our dogs when I spotted this snake, after my wife and a couple of dogs had not noticed it as they passed by. 1969. They were much more lively than I thought they would be after making such a trip….some even ate a few crickets immediately. Choruses can be heard from November thru February as the species breeds all winter. • Gopher Snakes are non-venomous. This was probably the smallest ensatina I’ve ever seen, certainly shorter than an inch in total length. Amphibians and reptiles of western North America.

After everyone got all the pics they wanted, we moved on to the next spot, where more newts, ensatinas and slenders were found, along with a beat up, rather sorry-looking little Santa Cruz Garter was seen out basking in one of the few sunny spots around. Thanks again to all those who helped! Museums of the day held opportunistically collected specimens from scattered sources, but rarely did these include ocean-bound birds that spent little time near the coast. First snake before dusk was wicked fast, and loved human flesh. We have an area here where they get especially black in color and have the most incredible iridescent blue bellies. If you love your device and love nature, grab your gadget and get outdoors with us on our first SDRVC “Tech Trek” coming in November. A., paid assistants and student volunteers aboard the Colorado.

– COSEWIC 2006. The California Department of Fish & Game reintroduced tule elk to Tomales Point, Point Reyes National Seashore in 1978. Many of the fragmented populations no longer have corridors of access to other populations, and one wonders about the eventual genetic effect of in-breeding. I did not take the lengthy photo-shoot that I wanted as I had an alert message of an approaching sandstorm In that brief moment it seemed that I would have to settle for one “ok” picture but a thought occurred to me that the branches of the creosote branches could be lifted to let in the sunlight for a photo, which was what I did. Many factors are believed to have caused Oregon spotted frogs to decline and continue to threaten this species, including loss of habitat, non-native plant invasions, and the introduction of exotic predators such as bullfrogs. Here’s an adult female Side-Blotched Lizard looking warily at me from its boulder perch. Though not nearly as bleak a scenario as this, it is true that some of the animals found in urban areas like Lake Merced will be familiar to city dwellers – raccoons, opossums, rats, and mice.

Check the range map – there is little range overlap. Greatest activity occurs from April to July (Stebbins 1954).

Retrieved 20 August 2015. ^ a b Shannon Hiatt. Herpetol. My friend David Sloo and I watched this whiptail nervously excavate some sort of crunchy wiggling morsel.

There certainly seems to be the opportunity during this annual pond congregation to mix genes in many different combinations, but I am not sure if newt biology and female patience works that way. At first glance I thought it was a discarded bracelet. Snakes do not have eyelids. The study of biology is increasingly moving into a diversity of animal models, taking a comparative/evolutionary, or integrative, point of view, hence a greater interest in herpetology. The precise times of migration for both species, to and from the breeding ponds, occur during periods of sustained nighttime rainfall. This large glossy snake was the first live snake I found on a second night of road-cruising in Anza-Borrego. However, much of that information now needs to be updated.

Two dark-bordered light stripes mark each side of the head, extending from the back of the eye and from the back of the angle of the jaw. Purple: Area representing recently-discovered boas of unexamined species, most likely C. Able to tolerate very high temperatures, higher than any other North American reptile. – Detaching the tail, which wriggles on the ground to distract a predator from the salamander long enough for it to escape.

Red: Eleutherodactylus coqui – Common Coquí (Red indicates the counties where this frog has been found and may or may not be established.
