After the introduction we headed toward the river. We took the middle trail and looked around logs and other debris for reptiles. It seemed we were going to come up empty when the sun began to come out and Mike spotted a fence lizard on a log. The lizard obliged by remaining in place for many minutes while people gathered around and took photos.
Then we got a summons from people up the trail: a rattlesnake!! A young rattler was curled in the grass under a log, minding its own business until all the eager naturalists came along. Mike had the right equipment, a blunt hook, and calmly picked up the snake for display. The young snake didn't seem at all concerned; it relaxed on the hook and posed for photos while Mike gave a snake lecture and answered all our questions (no, young snakes don't have more potent venom, they have smaller venom sacs so their bites are usually less dangerous). After the talk Mike released the snake with the reminder that it has a whole family, including parents there in the grass.
We walked back along the beach, enjoying the birds along the way. Another magical FORB event.
