Black Tailed Horned Viper in Mexico

A cool little viper with horn-like scales above the eyes. That’s a common thing with arboreal vipers in Central and South America, but vipers with “horns” are relatively few in comparison. They’re closely related to other montane vipers in the area that have similar structures, but live more familiar lives in steep, heavily vegetated forests.

A few hours of careful scouring of perfect habitat turned up none of these. Then after having more or less given up, I decided to flip some rocks near the cars while we waited for the crew to reassemble … and poof: the target. It’s fun when that happens.

Banded Sandsnake

A Banded Sandsnake from my own backyard. These are tiny, even as adults. This one is a bit shorter than a pencil, and likely won’t get any bigger. They eat invertebrates, don’t bite, and are completely harmless to people and pets. They’re also very often mistaken for Western Groundsnakes, which look superficially similar.

Longnosed Snake in the Daytime

A Longnosed Snake cruising around in the low light at the end of the day. These snakes are most often nocturnal, but may be found in the early morning or late afternoon, especially in the Spring. Against the chaotic, rocky backdrop of desert pavement between sandy plains, its shape breaks up, and spotting it can be difficult.

These snakes are commonly found in backyards, even a decent distance into the city, where they are usually misidentified as kingsnakes.
