The spider pictured is a female. The males are much smaller as is usual in the spider world.
She was pretty close to the ground with rocks on one side and shrubs and bushes on the others so I was challenged to get these picture which in my estimation are not that great. Sorry. Some day I'll have a camera that works better.
In their web there is a zig-zag pattern they weave. It runs through the center of the web and is called a "stabilimenta." The purpose of this unpronounceable thing is to reinforce the web so it doesn't require repair as often. Studies have shown the inclusion of the stabilimenta results in
fewer "catches" but it also results in less damage from birds as they can then see the web and avoid a collision.
One really cool thing that I thought was amazing was the spider will bounce on it's web if you lightly touch it. We observed this and at first thought that maybe the web was stuck to the camera strap or something similar. It turns out it was this spider bouncing away.
So that's the big gee-whiz at Red Tail Ridge on this 10th anniversary of the tragedy 10 years ago in New York.
Whoohoo Y'all...

I think your camera does a good job. I've always enjoyed the pictures. Never heard of bouncing spiders- now I'm educated a wee bit more.
