Some great suggestions. Thanks. Hope to take more under different lighting conditions. Just want to assure you that we do not interfere with the foxes and that is why you see the sticks, etc by the hole. We do not touch or alter anything around the den area. They do not seem to be very mobile yet and spend a lot of their time sleeping in the hole, and wander just a little away from the hole and then back. Whenever I have encontered the parent, he/she just took off. No attempt to guard the den. We keep the photo shoot short so as not to interfere with feeding by mom and dad. When you see examples such as these you do gain a much greater appreciaiton of nature. Jeff and I went there yesterday and he got a few shots but had to wait for them to appear (they were in for a nap). Hopefully he will post some of his photos.
