Thanks, for the comments, guys. Finding out that my boards were producing has been the brightest moment in a long, dark winter.
Froot, believe it or not, I've never flipped an angry rattlesnake. In the wild, they're pretty dependent on crypsis to hide them. When you flip one under a board, you've usually got a pretty good chance to get some good
in situ shots, provided you're careful not to startle them further.
I'll keep my fingers crossed about summer. It's up to -2C today, so we're definitely headed in the right direction.
Wes, how about private property? That works well for me, but I really don't know the situation there. Here, we have plenty of fire wood and cheap building materials, so piles of boards are generally looked at more as unsightly litter than an opportunity for scrounging. (I usually only get permission after explaining the scientific merits of surveying their reptile populations and promising to keep my study areas from becoming an eyesore.)
Bushviper, I would be absolutely heartbroken if one of my board lines was raided by poachers. Luckily, all of my board lines are extremely well-hidden, either on private property or hidden in remote wilderness, and (most importantly) within states that don't hold round-ups. Arizona treasures it's rattlesnakes (even poaching a single 'winder or
atrox is punishable by six months in jail), and Michigan's only species is protected.
I did have one board line that started life as a pile of old signs that was located just outside some redneck's fence. After getting tired of finding dead rattlesnakes near these signs (I knew it was him because I've actually seen him stop in the middle of the road and shoot one, not more than a dozen meters from the signs), I "liberated" the old signs and started a heavily-camouflaged line not far away. Immediately afterwards, we managed to record at least one mated pair at the new site. As of this Spring, the big male has returned. Hopefully, the females won't be too far behind.
