Thanks for those notes, Bonnie! It is educational to include information from websites, but the links to them can be put in the reference section. Then you could put information like where you saw the wildlife in the habitat section of the spotting and the other information in the description and/or notes. Those personal details make the spotting more interesting for the viewers and you may attract more attention with your spottings that way. The information you gave below made your spotting all the more interesting!!

We were camping at Lake Winfield Scott Rec Area when this lovely creature made it's way across our site as we sat around a campfire. It was not happy with us at all, and made it's feelings known with a very loud rattle when I got too close with my camera. It was on the smaller side, about 3' long, but it made a very big sound! We just stood back, gave it some room, and it went on it's way. It was a real beauty. Seeing it up close and personal was the highlight of my day.

Nice spotting, Bonnie! Could you please mention in which specific habitat you saw this rattler? (e.g., during a walk in a nature reserve, near your home). It looks like it was rattling when you photographed it!
