Description

A team of Christmas Bird Counters had just finished a 2-mile hike through a large grassland and along the edge of the San Gabriel River when we encountered a couple of rattlesnakes out sunning themselves on a rather cool day. Weather only warmed to about 65F (from a low of 40F) and there was a gusty S wind 20 to 25 knots.

I'm not sure if the very dark coloration of this individual is simply a function of the season or something else.
